You are the Captain in charge of controlling a colossus cannon on planet X Alpha 52. The enemy placed hostile cannons behind the mountain. With the wind speed changing, control your cannon to shoot projectiles above the mountains to hit the enemy. You do that by analyzing the information on 3D mini-map.
The enemy will fire back at you, and you will be destroyed if you get hit after your shield is destroyed. To defend yourself, you are equipped with RPG launcher and shells. While trying to hit the enemy, you have to load your RPG launcher and shoot down incoming enemy projectiles as necessary.
