Iceberg Interactive announces April 26th is the release date for StarDrive, Zero Sum Games' upcoming 4X space strategy game. The game went on sale last month on Steam in a preorder program that grants access to the game's beta, and word is the preorder 17% bonus will continue until launch week, when it will drop to 10%. Here's a refresher: "StarDrive is a space-themed 4X strategy game with deep ship design, colonization, diplomacy, research, and beautiful 3D graphics designed by new developer Zero Sum Games, which ran a successful Kickstarter campaign in 2011."
