Battle AI pilots
Colony Battle Royale is a single-player survival match. Collect supplies and weapon pickups, watch your shield and hull, and aim to be the last mech standing.
How to play Mecha War
- Start your first encounter. Open the game and press PLAY. The opening battle introduces movement and aiming before you explore the hangar.
- Use cover and manage your boost. Turn with the mouse, move between buildings and avoid standing still in an enemy's line of fire. Watch the boost meter when you jump or accelerate.
- Collect and compare weapons. Matching primary weapon pickups can equip a second weapon or merge into a stronger one. Hold E near a different primary weapon to swap. Mount weapons provide limited-use attacks.
- Stay inside the safe area. The colony battlefield closes over time. Move ahead of the dangerous end caps and keep track of the remaining opponents.
- Return to the hangar. Review the battle, change your loadout and use earned gold in the shop. The Tutorial button gives you a separate place to practice movement and firing.
