Tripod attack is an alien invasion game where YOU are playing the alien! Fun right? You must use your ray energy to destroy the attackers which are trying to take you down. The ray energy has a cool down so make sure you use it wisely. You also have something called a Shield energy where it restores if you don't receive any damage. You also have armor which decreases when your shield is reduced to Zero. You can repair your armor in the upgrade menu. To shoot people with your ray, you must use your left click mouse button to destroy everything you can. You can upgrade your skills under the "Upgrade Menu". We hope you enjoy this great unblocked game!
