She probably shouldn't have stolen the guns and gold from those bandits. And getting that bounty put on her head doesn't help much either. The lawmen aren't too far behind the bandits. No way out of this one, might as go out with a hell of a bang.


A frantic and fast-paced 2D arena shooter with an eye for (gun) details. Earn a high score and increase the bounty on your head while fighting on a runaway train crawling with enemies.


Already Implemented:

- 8 unique guns that mimic their real life counter-parts
- 4 Unique enemies and 2 variants
- Shooting enemy bullets out of the air
- Meticulously designed gun sounds
- Multiple train level layouts
- Detailed stat tracking
- Life highest scores tracking
- All original art and music

Features Planned:

- Even more levels
- Unlockable cosmetic customization options
- Playable Prologue
- Multiple Game Modes
- Gun Gallery
- Lifetime stat tracking
- Local highscore table tracking


We want to reach as many people as possible, so we will also be posting this game for free on our website! However, if you like the game please consider supporting us by purchasing it on Steam.
