TITANS 1v1 Ranked Ladder Season 2

Posted by Planetary Annihilation Inc (Creator)

Hello Commanders,

Season one of 1v1 ranked has ended, so let us give our congratulations to [TNC] [Nik] NikolaMX, a player so humble he put his own name in a clan tag.

Fighting off many worthy opponents he has dominated the Uber league, holding the #1 position for most of the season. An Invictus statue will be on its way to our deserving season 1 winner.

Season 2 – 2019-01-25 to 2019-04-25

It’s season 2!

All ranks have been reset; everything is up for grabs again.

A new season needs new maps. As you know we introduced four new maps mid-way through the previous season, and they’ll be carrying over to season two. But the rest of the maps have been taken out back and… retired. Sleep well old maps, you’ve served your time. Replacing them are eleven brand new maps.

Season 2 Map Pool (15)

  • Aquilaris (WPMarshall)
  • Bulkhead (WPMarshall)
  • Canyon (WPMarshall)
  • Centax-3 (Grand Homie)
  • Disparity (WPMarshall)
  • Enfer (Grand Homie)
  • Geonosis (Grand Homie)
  • Lost Temple (WPMarshall)
  • Lugaan (WPMarshall)
  • Niflhel (Grand Homie)
  • Riddler (WPMarshall)
  • Singe (WPMarshall)
  • Tartarus (Grand Homie)
  • The Ardennes (Grand Homie)
  • The Marne (Grand Homie)

New maps mean new strategies, and everyone is on an even footing because no one has had a chance to practice these before. We look forward to seeing what you make of them and hearing your thoughts on how they play. These maps will also be made available to play in custom lobbies in the near future.


Of course, what season is complete without prizes? And what could possibly top an Invictus Commander statue? Like that relative that doesn’t know what to get you as a present, we opted for cold, hard cash. Nice.

The player who holds Uber #1 at the mid-season point (2019-03-08 00:00 UTC) will be awarded US$500. The player who is Uber #1 at the end of the season (2019-04-26 00:00 UTC) will receive US$1,000.

But what about those of you playing in Bronze reading this and thinking, I’m never going to hit Uber so what do I care? Well we’ve got you covered too. We’ll be awarding US$100 to the most active player in each of the five leagues, both mid-season and at the end of the season. Doesn’t matter where you rank in the league, only how much you play.

Summary of Prizes

Mid-season at 2019-03-08:00:00 UTC

  • Uber #1 - US$500
  • Most active Bronze player - US$100
  • Most active Silver player - US$100
  • Most active Gold player - US$100
  • Most active Platinum player - US$100
  • Most active Uber player - US$100

End of season 2 at 2019-04-26:00:00 UTC

  • Uber #1 - US$1,000
  • Most active Bronze player - US$100
  • Most active Silver player - US$100
  • Most active Gold player - US$100
  • Most active Platinum player - US$100
  • Most active Uber player - US$100

Maximum annual winnings for Uber #1 is US$6,800 if you hold the position all year and play the most!

All prizes are awarded at the discretion of Planetary Annihilation Inc. Players in breach of the Planetary Annihilation Community Rules and Guidelines may be disqualified. The decision of Planetary Annihilation Inc is final.


Seriously? We spent a lot of time writing all that. Millennials are ruining the patch note industry.

  • Ranked season 2 has begun
  • New ranked map pool
  • US$2,500 to be won this season

Let the soothing voice of WPMarshall take you on a guided tour of this season’s maps.

Happy New Year Update 112589

Posted by Planetary Annihilation Inc (Creator)

Happy New Year Commanders,

Our faster modern toolchain server build with multi-threading is now live on official servers! This should mean the servers perform better than ever before, especially on multi-planet systems.

The modern client with local server remain opt-in via the modern BETA in Steam and the PA launcher. If you are playing single player with a local server or hosting LAN games we encourage you try the the modern client.

To help new players pick up the game faster, the Planetary Annihilation guides section is now a one-stop shop for everything you wanted to know about Planetary Annihilation but didn’t know to ask.

We have expanded the TITANS 1v1 ranked map pool with four community maps from WPMarshall and GrandHomie (for a total of 15 maps):

  • Enfer (GrandHomie)
  • The Marne (GrandHomie)
  • Lugaan (WPMarshall)
  • Singe (WPMarshall)

Your complaints about dodging in ranked have also been heard. Not only have we removed ranked queue status information from Community Chat, we’ve also anonymised names in the ranked lobby and removed the ability to leave the lobby. You really are trapped in there with your opponent now, so don’t queue if you don’t intend to play.

We’ve also got AI upgrades for the single-player and comp stomp crowd. The neural network’s fitness function (it sounds technical which means it’s impressive) has been reworked so that the AI is smarter about the way it evaluates battles.

Another long-standing AI request was the ability to select which Commander the AI uses. We promised to add this and so we have. Please feel free to admire the new Commander selection UI, making better use of your screen real estate.

We’ve continued to keep an eye on crash reports and have put a lot of effort into eliminating everything we can. You should find Planetary Annihilation an even more stable experience than before. We’ll continue to keep an eye on things to see what else might crawl out of the woodwork. Some of these things can be pretty edgecase, but we won’t stop in trying to track them all down, we hate crashes even more than you do.

Audio modding has arrived, so modders can now add whatever sounds they like to the game, either overwriting existing sounds or even adding completely new ones. Give your new unit its own style as it threatens doom to its enemies. Break subwoofers everywhere with extra bass in every shot sound effect. Replace the in-game VO with your own voice so you can literally congratulate yourself on your wins, you egotistical monster. We look forward to seeing what you come up with.

As a final thanks for continuing to play Planetary Annihilation TITANS we have added two NEW dedicated servers running the latest modern linux builds that can handle epic games of up to 32 players. A number of trusted community members have been given the keys, so keep an eye out in Community Chat and the official Planetary Annihilation Discord for announcements of big games. You haven’t truly won a game of Planetary Annihilation until you stand victorious on the wreckage of 31 other Commanders.


  • Official servers using modern toolchain builds with multi-threading
  • Two clients available (stable legacy and cutting-edge modern for testing)
  • 1v1 ranked maps expanded with four community maps from WPMarshall and GrandHomie for a total of 15 maps
  • 1v1 ranked lobby is now anonymous showing Player 1 and Player 2
  • 1v1 ranked lobby leave option has been removed
  • AI improvements with reworked and retrained neural networks
  • AI commander selection (as promised)
  • Server crash fixes
  • NEW official guides:
  • NEW audio modding
  • NEW official dedicated servers with up to 32 players for big games


TITANS Balance Changes

  • Pelican cost increased to 160 and health decreased to 150
  • Locust cost increased to 260
  • Spinner range increased to 120


Technical Notes

Next year we will be moving to PAnet, which will replace the legacy UberNet infrastructure with modern server environments. Eventually all the legacy Windows servers will be replaced with faster modern Linux servers.


Software development toolchain:

Legacy toolchain

  • Visual Studio 2012 / Windows 8 SDK
  • Xcode 5.0.1 / macOS Mountain Lion for macOS Lion 10.7+
  • Legacy Steam Linux runtime / GCC 4.8.4

Modern toolchain

  • Visual Studio 2017 latest / Windows 10 SDK latest
  • Xcode 10.1 / macOS 10.14.1 latest for macOS Mavericks 10.9+
  • Modern Steam Linux runtime / GCC 5.4.1 (currently limited by Steam Linux runtime)
  • Native Linux / Clang / LLVM 7.x for dedicated Linux servers

TITANS Community Maps

Server Improvements

  • Faster modern toolchain build

AI Improvements

  • Completely reworked the AI’s neural network fitness function to improve how the AI evaluates the outcome of a battle
    • Instead of being based on the difference between each and every input before and after the encounter, the fitness function now primarily looks at which side lost more metal value. Not every encounter results in a metal loss, so the fitness function also compares unit count losses as well as health losses, but they don’t count nearly as much as metal losses
  • AI commander selection in new game lobby

Server Fixes

  • Fix for crash if the AI was trying to teleport a fabber or commander to a planet as the planet was destroyed
  • Fix for multiple cases where a unit could be removed from a platoon (dropping the reference) before being added to a new platoon, causing a crash later on in the game
  • Fix for crash if the commander did not have an Uber cannon spec
  • Fix for build arms not ticking in multi-threading enabled servers causing fabbers/commanders to not face their build targets
  • Fix for crash if a fabber/commander was assisting in the construction of a projectile that died
  • Fix for a crash if a projectile target died and was cleaned up by the sim
  • Improved fix for players disconnecting from new game lobby not being removed from game

Client Improvements

  • Reorganised start menu is now scrollable with more space for menu items
  • Improved commander and colour selection in new game lobby

Client Fixes

  • Fix for ESC key locking up the start menu if no video was playing
  • Fix for community videos not showing if community mods not enabled


  • NEW audio modding:
    • api.sound.playSoundFromFile(path)
    • api.sound.playSoundFromFileAtLocation(path, x, y, z)
    • api.sound.registerCueMod(cue, path)
    • api.sound.unregisterCueMod(cue)
  • NEW build.txt with original build number (will differ from version.txt for legacy clients)
  • NEW gBuild global with original build number from build.txt accessible in all scenes
  • NEW --version command line option to override version.txt for targeting a different server build

Multi-threading, Performance and AI Improvements Updates 112176 / 112209 / 112214

Posted by Planetary Annihilation Inc (Creator)

Greetings Commanders,

It took us a little longer than we expected to prepare this build in light of some server issues last weekend, which are now resolved.

This is our first new build on the legacy toolchain and will be the first of many once we stablise our modern toolchain builds.

Our focus is on speed and stability as we work to ensure we’re in the best place possible ahead of upgrading the technologies which underpin the game. We’ve implemented numerous server sim performance improvements, while also resolving a number of the most common causes of server-side crashes.

You should still make sure your graphics drivers are up-to-date as out of date drivers are still the most common cause of client issues. Seriously. Go do it now!

Over time we’ve seen the competitive meta settle, revealing some very visible imbalances. No one likes those. We’ve introduced some small changes to fix things. Balance is as much an art as it is a science, so we’ll continue to monitor and adjust as necessary.

The AI has also seen some love, upgraded to be more ruthless than ever. It’s in it to win it, with an upgraded neural net, along with additional behavioural improvements.

Finally, rumour has it some kind of ladder reset is fast approaching...


  • Advanced Air, Bot, Vehicle and Naval Factory cost increased by 25% to 4,500 (minor delay to T2 rush)
  • Slammer cost increased to 500 (minor adjustment against Leveler)
  • Solar Array cost decreased to 1,600 (minor adjustment against land-based advanced power)
  • Gil-E vision increased to 220 (vision now matches weapon range)
  • Bluehawk range increase to 220 (buff as a counter e.g. Kaiju)
  • Pelican health increased to 200 with group (formation) preference set to back (increased survivability)
  • Stingray vision increased to 250 with new radar and sonar of 350 (new cruiser role as naval radar)
  • Typhoon vision increased to 250 with drone guard radius of 250 and passive health regen reduced to -2 (20 seconds)
  • Kaiju rate of fire decreased to 0.5 shots per second (minor nerf)

Technical Notes


  • Adjusted the neural network fitness function
  • Neural networks have all been re-trained for Titans and Classic
  • Threat response platoons now see amphibious units as anti-sub threat
  • Added a couple of new target filtering options, a new neural net input, and a few new outputs
  • AI does a better job of gathering and using intel as well as caching it for later use to improve performance
  • When looking for a place to attack, the AI will now take into account neighbouring areas when determining what size of a force to use
  • The AI will now look for more fights that it can win rather than fights it can at least tie
  • Fix for AI platoons that would get stuck trying to disband
  • Adjusted how much the AI raids Improved AI neural data merging
  • Adjusted AI aggressiveness

Server / Simulation Performance

  • Adjusted how search spaces are updated in an effort to get through as many of them as possible per tick
  • During the nav update, more of an effort is made to allow as many search spaces as possible generate their high level path so units can start moving faster
  • Added a fail safe to allow nav to steal more voxel budget if it is having a tough time getting through search spaces
  • This will give nav an opportunity to fulfill a larger number of move requests over a shorter time
  • We now query a search space to ensure we have enough voxel budget remaining for the space to prevent doing a bunch of useless work
  • Added the count of updating search spaces in nav to the perf output window
  • More aggressive filtering of collision pairs to reduce the number of pairs we have to check
  • Nav now attempts to pre-allocate the cost cells it will need for the updating search spaces it has
  • Search spaces now return their cost cells to nav when they are finished so they can be reused later
  • Moved the spatial DB update for dynamic objects so that it only happens once, at most, per update

Server / Simulation Multi-Threading

Please note multi-threading must be enabled for your server.

  • The task scheduler now supports running the plan step of parallel tasks (such as weapon auto targeting and auto manoeuvring) at the same time, per unit
  • Entity record step now runs in parallel
  • The nav and physics updates now run alongside the economy update
  • Added multi-thread support for the heavy parts of the recon update
  • Units can now update their weapon aims in parallel
  • The physics update now supports multi-threading
  • The small island build is now multi-threaded per sector
  • This helps in-game perf as well as system loading
  • Added --max-threads command line to set the max number of background threads

Crash Reporting

  • Improved crash reporting for all platforms
  • Crash dumps are now stored in the log folder (varies by OS) instead of a temp folder
  • On Windows, a DxDiag report (stripped of all personally identifiable info) is now automatically attached to crash reports

Crash Fixes

  • Fix for crash if, during the same tick, a search space was marked for removal and then another search space was created for the same destination
  • Fix for rebuilding the collision geometry BVH when it wasn't needed Fix for crash in swizzle tree from trying to evaluate log(0), in a rare case
  • Fix for big game crashes caused when the flood runner gets a request from a search space with an invalid goal location
  • Fix for virtual texture binding crash on the client


  • icon atlases now use grids which increases the maximum strategic icons (52x52px) on an 8K texture (older GPUs) to 157 x 157 (24,649) and on a 16K texture (modern GPUs) to 315 x 315 (99,225) resulting in a breaking change to the following shaders:
  • particle_direct_ring_selection.vs
  • particle_direct.vs
  • particle_icon.vs
  • particle_status_icon.fs
  • particle_status_icon.vs
  • strategic icon mods should use the new utility function calculateAtlasUV (added to particle_common.vs) replacing: v_TexCoord = vec2(a_TexCoord.x, vUVAndExtra.x + vUVAndExtra.y * (1.0 - a_TexCoord.y)); with v_TexCoord = calculateAtlasUV(vUVAndExtra.xy);

Server Issues Resolved

Our legacy infrastructure hit a 10GB limit for archived game summaries. That's a lot of games!

64 bit - The Future of PA and Titans

Posted by Planetary Annihilation Inc (Creator)

Hello Commanders,

Today marks the six year anniversary of the Planetary Annihilation Kickstarter, where 44,162 backers helped breathe life into the concept of a next-generation RTS, where thousands of units would clash across multiple worlds, unleashing interplanetary destruction.

It's been a long road and we’d like to say a big thank you to everyone who backed, supported or just played Planetary Annihilation over the past six years; we couldn’t have done it without you!

The incredibly sexy technical work continues behind the scenes. After the next major update we will be focusing on 64-bit operating systems as we continue to modernise Planetary Annihilation. If you're part of the 2% still on 32-bit Windows now would be a good time to upgrade so you can fully reap the benefits of the changes we’re making.

Similar to Valve, Blizzard, Nvidia and many other game developers, this modernisation necessitates saying goodbye to some unsupported, end-of-life operating systems like Windows Vista, and older macOS / Linux releases. We'll confirm the details prior to our modern build going live and plan to make unsupported older builds which will continue to work in offline mode available to anyone who cannot upgrade.

We have also performed a much needed refresh of the community rules and guidelines, after all we don’t want our little pocket of humanity to fall into discord and be overthrown by the Machine Liberation Army. There’s even a tl;dr version, because we know you want to be playing PA not reading rules. These apply to all aspects of PA: lobby names, in-game chat, official forums and the official Planetary Annihilation Discord server, which is now live.

Please feel free to use the official Planetary Annihilation Discord server to coordinate games, discuss strategies, seek out help with modding, and anything else PA related. We also hear there’s more to life than PA, and while we’re not sure we believe that, we have created an off-topic channel just in case.

See you in Discord -

The PA Team
