More about Planet Killer
Planet Killer is a physics-driven sci-fi destruction roguelite. Players orbit hostile worlds, unleash devastating weapons, carve real craters into fully simulated planets, and trigger chain reactions while escalating planetary defenses fight back. Core gameplay involves permanent battlefield reshaping through real-time crater carving and shockwaves. Each run features procedurally generated planets with unique cities, terrain, and space environments. Players build modular weapon stacks to counter evolving defenses, with up to 6-player co-op. The game includes over 128 starting ships, permanent run-based death, and a progression system where players unlock titles and ranks through destruction. Every shot leaves permanent terrain fractures, causing planetary collapse.
