Free Game: Alien Guard 3
If you’re getting tired of Hidden Object games and typing tutors, it may be time to try a free flash game that has a ton of action in it, while still containing silly, likeable characters. Enter: Alien Guard 3 from Ultimate Arcade:
The game has you controlling a weird little orange alien named Nanny, who is armed with a machine gun and protected by a helmet. The game doesn’t specify exactly what you are guarding, but you have a gun and there are other aliens (including UFOs!) who want to shoot and bomb you into oblivion. Make sure you use nanny’s trusty machinegun to get them first.
The game is much easier to control than other web games, since it uses the arrow keys for moving and the mouse button for shooting (compared to other webgames that use the arrow keys and the z,x, and c keys, which is unintuitive for righties).
