Attack humans by biting their heads and eating their brains! You are the Headcrab monsters, and this launching game demonstrates your Invasion and anger against mankind. Upgrade your alien skills up to the max, hire silly people to aid your plans, devour as more brains as possible, and see how long will it takes to get back to your alien homeland! Use the Mouse to jump and use abilities from the current victim.
