Cheating Dome presents: Alien Overkill for Android
When you reach the difficult modes it starts to become crucial that you collect ALL the health packs enemies drop. To get you through tougher waves keep an eye-out for Nuclear weapons and power-ups like 'Invincibility'. It is only possible to hold one weapon at a time so it is best to stick to a combo of rifle or shotgun with a flamethrower or RPG for dispersing larger groups of aliens.
