Planet Killer description

Planet Killer

Planet Killer is a physics-driven destruction roguelite that casts you on a mission to locate hostile worlds and reduce them to molten ash. Every shot permanently reshapes the battlefield, forcing you to improvise as gravity, momentum, and material properties bend to your will. You begin with a single ship, each with its own strengths and weaknesses that steer your opening gambits. As you smash planets into dust, you unlock new vessels that widen your tactical options. The core loop mixes precise aim with dynamic terrain: the remains of each world become your next weapon’s playground and every victory opens new possibilities for conquest.

Planets are fully simulated, pixel-based canvases where real-time crater carving matters. As you fire, you carve craters, generate shockwaves, and trigger chain explosions that ripple across the surface. The terrain permanently remembers every impact: fractures spread, shelves collapse, and the world buckles under sustained bombardment. Defenses retaliate in kind, and escalating planetary defense systems begin to push back harder with surface cannons, missile batteries, and active countermeasures designed to thwart predictable patterns. Each world offers a new palette of fortifications and tricks, demanding adaptive tactics and careful resource management if you hope to reach the deeper, more hostile realms.

Your loadout is a core pillar of the experience. Build from hundreds of modular weapons and systems to craft devastating combinations: missiles that chain into bombs, rapid-fire cannons that carve through armor, lasers that slice through thin atmospheres, and experimental devices that feel like pure chaos. Defensive modules and utility tools stock your ship with survivability and strategic options. The right mix depends on the target’s layout and defenses, so experimentation is rewarded. As you destroy planets, you unlock further gear and configurations, ensuring that every run can introduce a wildly different setup and a fresh route to planetary domination.

Roguelite progression drives every ascent into the void. Each run features procedurally generated encounters and a steadily increasing difficulty curve, testing your adaptability and reflexes. Permanent death makes each decision meaningful, turning the cosmos into a leaderboard of your prowess. High-score chasing and unlocks give you long-term goals: new starting ships, more weaponry, and increasingly powerful tools to erase worlds. The combination of perpetual customization, harsh risk, and limitless experimentation creates a loop where no two voyages are alike and the appetite for destruction only grows with every planet you scar.

How many worlds can you erase before you fall? Step into the void, arm your ship, and carve a path of annihilation through the galaxy—one pixel, one crater, one dead world at a time.
