The Introversion Website is now accepting preorders for Multiwinia: Survival of the Flattest, the multiplayer Darwinia spin-off that promises "the ultimate retro-arcade multiplayer experience." The game is due for retail release on September 19, and those who preorder will be able to play on that day, as they will receive a game key through the mail. Word is the game has three different preorder schemes: "There will be a three-tiered pre-order menu; digital download, digital download plus boxed unit, or customers will be able to treat themselves and purchase our limited edition special pack presented in a beautiful custom-made Darwinian tin. These Darwinia logo-embossed tins will be exclusive to the Introversion Store and will contain DVDs of both Multiwinia and Darwinia, a fantastic coffee-table book featuring award-winning artwork from both games, the complete postcard set of Multiwinia cartoons and our very own Darwinian foam toys, loved by journalists and fans alike!"
