As well as the full game, you'll get weekly beta test pre-release snapshots of the game in progress, and access to a special beta testers only forum for the duration of the development process. Your input will be vital to shaping the game!
You'll receive a USB thumb drive with a DRM-free copy of the game, plus the official soundtrack in FLAC (lossless) format, mailed to you on release, as well as two download keys for the game and the soundtrack that you can give away to your friends. Plus everything above.
We will work with you to design a new megacorporation that actively participates in the game, which the player can take over, and which will have a unique special ability that will affect gameplay. Of course you also get all the previous rewards.
