## What is Rotgun?

The dead don't stop coming. Your turrets do.

ROTGUN is a tower defense where you build the arsenal yourself. Put two identical guns side by side, merge them into something nastier, and keep going until the road is a meat grinder.

MERGE YOUR WAY UP
34 turrets across four branches - bullets, shrapnel, sniper, elements. Every merge is a real jump, not a stat bump: a pistol becomes a revolver, a revolver becomes a machine gun, and a few steps later you are firing an orbital laser.

HOLD THE LINE
The waves never repeat themselves for long. Runners rush you, tanks soak everything you have, flyers ignore the road entirely, healers patch up the horde walking behind them, and the boss shows up right when your gold runs out.

WAKE THE CORE
The crystal in the middle of the map is asleep. Awaken it and it burns a beam through anything that steps too close.

BUILD BETWEEN RUNS
Blueprints unlock in the Lab the deeper you survive. Crystals raise damage, fire rate and range for good. Every run you lose makes the next one start stronger - nothing is wasted.

SEVEN MISSIONS AND ENDLESS MODE
Seven handcrafted missions, each with its own map and rules. Then endless: one road, no finish line, and a wave counter that keeps climbing as long as you hold.

- Plays fully offline, no internet needed
- Portrait, one hand, works for two minutes or two hours
- No energy bars, no timers, no waiting to play
- Available in 11 languages

How far can you hold the line?
