From the developer

Nebula Marshal is a 3D space-western survival shooter. Pick one of 6 heroes, land on a hostile planet and hold out against endless monster waves. Your guns fire automatically: move, dodge and grab crystals to level up. Stack 9 weapons and 16 modules, then evolve weapons into legendary forms like the Golden Six-Shooter.

Every 2.5 minutes a WANTED bounty boss shows up, and the deadliest one arrives at 10:00. Conquer the Rust Wastes, Frost Frontier and Neon Canyon, raise your Wanted level for bigger rewards, complete daily contracts and spend credits on permanent upgrades in the Hangar.

Tips

• Plan two moves ahead before tapping. Tile trays fill up faster than you expect.

• Reload during quiet moments rather than mid-fight.
