The Infinium Strike website now offers a playable Windows demo for Infinium Strike, the game developer Codex Worlds calls a "unique take on tower defense." The game has been approved by Steam Greenlight, and they say they are planning a Kickstarter before releasing the game this fall for Windows, OS X, and Linux. Word on the game is: "Infinium Strike puts you in charge of weapon systems aboard Freedom Strike—the largest, most heavily armed ship in human history—as you defend against hordes of sentient alien ships, called The Wrog."
