How fast does your damage actually grow?
The game publishes its core rule: every hit = +1 DMG. Our free damage calculator turns that rule into real numbers — how much damage a grinding session yields, how long a DMG target takes, and what a better gun (official art shows a +67 per-shot rifle vs the +1 starter) does to that math. The WELCOME code alone jumps you to 5,000 DMG.
The loop in five steps
- 1
Shoot the AI robots
It is a first-person shooter: robots walk toward you and you shoot them. The official rule is simple — every hit grants +1 DMG.
- 2
Damage stacks with every hit
Your DMG is cumulative. The more you shoot, the harder you hit — the game's own tagline is "Get stronger with every hit".
- 3
Earn Medals & unlock better guns
Medals come from playing, and better guns raise your per-shot damage. Official art shows the jump: a starter pistol at +1 per shot versus an upgraded crystal-style rifle at +67 per shot.
- 4
Fight through new areas
Official media shows several environments — a dusk industrial skyline, a blue tiled arena and a bright blocky city. Area names are not published yet.
- 5
Face stage bosses (V1.2)
Update V1.2 added "Stages BOSS". Boss names, counts and rewards have not been published by any source yet.
