Shoot down every single bandit until the wanted criminal is drawn out. Assassinate the level bosses to proceed to the next level. You will have a wider arsenal of weapons as you progress and the bosses will get tougher.
Try to stay alive and survive the testing procedures of Platcore. Your robot is dispensable so there are other robots to play if yours gets destroyed. Keep in mind that the game soundtrack is synced with the Platcore AI.
