What it is
Perimeter is a science-fiction real-time strategy game from K-D Lab, set in a future where the Exodus civilization has left a dying Earth. Players compete against other players or AI to claim territory and maintain protective perimeters. Its central terraforming mechanic lets players alter the battlefield itself: move, build, construct, or destroy parts of the environment. The game combines territorial conflict with traditional strategy, with three-dimensional map changes shaping how players approach each match. Perimeter includes single-player and multiplayer, as well as Steam Cloud, Steam Trading Cards, and Family Sharing. It is available for Windows. The original GameSpy service shut down, but the listed ways to keep playing are LAN, DirectIP, and GameRanger. The game’s release information includes a 2004 release year and an April 3, 2014 Steam release date.
