In Color Wars, you'll be shooting up orbs that will multiple and threaten your health if you don't kill them first. Use the mouse to move around and click to shoot. If you want to hold your ground and shoot from a stationary location, you can use the space bar to anchor yourself down. The trick is that you have to have a matching background color to shoot the different colored orbs. You will have to toggle between the colors with the designated keys that will pop up on the screen. In Color Wars, you switch from two colors and eventually more colors are introduced so you will need your concentration for this one!
