Screeps: Arena is an online asynchronous PvP strategy game for programming enthusiasts. You write real JavaScript to control your units, and they fight autonomously against other players in a 1v1 match-based arena environment.
Predators lurk, food is scarce, you must adapt - or go extinct. Evolve your species to survive and dominate as you explore the campaign or go head-to-head with the skill-based matchmaker.
