Planet Killer

Planet Killer is a roguelite in which the player pilots a ship against hostile planets and destroys them. Each planet is simulated at pixel level, so weapon fire carves craters, produces shockwaves, triggers chain explosions and leaves permanent damage on the terrain. Planets are procedurally generated and include cities, continents, islands, oceans and cloud or storm systems, set against varied backgrounds of star fields, nebulae and galaxies. Up to six players can take part together in online co-op.

Players choose a starting ship, each with its own strengths and weaknesses, and unlock further ships by destroying planets. Loadouts are built from hundreds of modular weapons and modules, including missiles, cannons, lasers, rapid-fire weapons, experimental weapons and defensive or utility modules. Planets respond with surface cannons, missile batteries and defensive countermeasures, and players can change their builds to deal with these defences.

Progression follows a roguelite structure with procedurally generated encounters, rising difficulty and tougher planetary variants such as elite planets, storm worlds and bosses. A galactic shop sells weapons, modules and ship upgrades. Death is permanent for each run. Players can rank up an emblem and title, pursue high scores and unlock more than 128 starting ships.
