About Astronium
Astronium is a metroidvania with souls-like aspects, focused on combat and finding weapons. You explore a hostile planet, fight strong enemies, survive ambushes and meet its inhabitants as you seek to leave.
Explore the planet
The world has four biomes, each ruled by a boss who governs through fear and terror. You encounter goblin ambushes, snow monsters, marine creatures and other threats along the way. Quests, encounters and NPCs are scattered throughout the world.
Fight and find weapons
Enemies can react intelligently rather than simply letting you attack. Each one has a chance to drop a unique weapon, and rare drops have special abilities. The game includes over 40 weapons with distinct movesets and powers.
Meet its inhabitants
You can encounter NPCs and sellers who may improve your life or bring it to an end.
