You are a survivor, abducted by aliens and thrown into a relentless battle against waves of extraterrestrial horrors and their twisted experiments. Your mission: fight through increasingly deadly enemy forces, infiltrate their warships, and put an end to their invasion before it's too late.

As you progress, you'll step through portals into worlds already ravaged by the aliens, aiding their inhabitants in reclaiming their home before taking the fight directly to the enemy’s homeworld. In this roguelike dungeon crawler, you'll gather powerful weapons, abilities, and relics to enhance your strength with each run. However, death is not the end—you'll respawn with only your base weapon, retaining only your character stats, forcing you to adapt and grow stronger every time you enter the fight. The fate of multiple worlds rests in your hands. Will you be the one to end the invasion once and for all?
