Brutal Legend -
The first thing you want to do is to press the right thumbstick to fly. Then follow the game's tutorial to learn how to control the wings. After that start building an army and make them attack the nearest fan-geyser. When that is taken care of your top priority is to eliminate the mortar tower protected by a Bouncer. When the Bouncer is dead you should continue with conquering all the fan-geysers.
