THE ALPHA - Everything above, plus guaranteed access to early alpha versions of the game starting in November, and your name in the special testers credits. You'll provide feedback on early builds and help shape the design of Rebuild: Gangs of Deadsville.
NAME A SURVIVOR - Everything above, plus random survivors in the game may use your real name, or a name of your choosing. If you're having trouble deciding on a name, I think "Sarah McSarason" has a nice ring to it.
PHYSICAL GOODIES - Everything above, plus a luxurious American Apparel Rebuild t-shirt in a rainbow of color options, and a sweet vinyl sticker to stick on stuff. These are Kickstarter exclusives. You'll get to vote for your favorite t-shirt design!
NAME A CITY AND ITEM - Everything above, plus you get to name a randomly generated city (eg Sarahville or Sarastapopolous), AND a rare scavenged item with slight stat increases (eg Sarah's Boom Stick).
YOUR FACE ON A SURVIVOR - Everything above, plus artist Adam will sculpt your likeness in vector form. Survivors in the game may randomly look like you. You'll be immortalized forever, even though your character will probably die many horrible deaths.
BE A ZOMBIE - Everything above, plus artist Sara will draw you in zombie form. You'll appear in an illustration during random events in the game, happily shambling and/or moaning and/or devouring brains.
NAMED CHARACTER - Everything above, plus your name and face will appear on a special character in the game's random events. Eg: you might be trader Gustav's little sister, The Government faction's military commander, or maybe a member of the Church of the Chosen Ones.
CORPORATE SPONSOR - Everything above, plus your company (or fictional company's) logo and name will subtly adorn a ruined building. Accompanying flavor text will poke fun at how obsolete your business is in a post-apocalyptic world.
