In A.L.I.A.S (Artificial Lifeform Intended for Assassination and Sabotage), you are an advanced cyborg, and your job is to stop the humans from discovering your secret base. Unfortunately, the security system in your own base has gone haywire, and it's trying to destroy you, too! Many of your friends from the original A.L.I.A.S game are here, and they're harder to kill. There are lots of new challenges, too, so watch out!
