Screeps: World

“Screeps” is a wordplay for “scripts” and “creeps.” It is an MMO RTS game for programmers in an open persistent shared world. Each player uses JavaScript (or compilers of other languages into JavaScript) to write AI of his or her colony of units (“creeps”) which live and operate in real time even while the player is offline. The game world is generated procedurally and consists of rooms. Players compete for controlling these rooms by mining resources, developing infrastructure, and commanding armies.
