Each plane not only has its own look but differs in characteristics. Some planes are quick but weak while others might be bigger in size and have different weaponry. The player will come across many different enemies from simple planes similar to his own to animals and UFO's. Most are in the air but there are also some ground targets that need to be taken down.
