A survey of an alien world

You are a Surveyor sent to map a hostile planet—one run, one route, one push to the end.

The deeper you go, the rougher it gets. Clear rooms, recover, choose your next step, and see how far this expedition can reach.

Choose the path

• After each clear, colored portals offer different routes: combat, rest, events, or challenges

• Sometimes there is only one door; sometimes you weigh two paths—play safe or take a risk

• Decisions happen between rooms

Black Boxes · one run, one build

• Clears, events, challenges, and bosses put Black Boxes in your path—inspect the item inside, then keep it or destroy it

• Some rewards hit the lottery machine: three choices on screen, take only one

• Once items stack up, the same room shifts from a grind to a chain-reaction clear—the deeper you go, the harder the snowball rolls

Room-by-room combat

• One room at a time: clear it, then choose where to go

• Combo and kill-rhythm feedback on the HUD rewards aggressive, clean play

• Breakable crates, chain-reacting barrels, treasure bugs—rooms hold surprises, not just enemies

Bosses and the final push

• Stage bosses test your current build and reflexes along the survey

• Push to the deepest point of the planet for the final confrontation

• Each run starts fresh; records and achievements carry over
