Alien Earth is an isometric action adventure game about aliens who have enslaved earth and keep humans around only to hunt for sport. In regular intervals the humans have to give up one of their own to ensure the survival of all. The player takes the role of Finn, who has been chosen to be the next prey. But he has no intentions of going down easy…

In seven levels he has to use both force and brain to survive. Puzzles are of the usual inventory based kind: picking up everything not nailed down, combining items and using then in the environment. There are also friendly people to talk to. Enemies can be killed with a variety of weapons, e.g. an axe or a high-tech pistol. Finn also has PSI abilities which grant him the possibility to heal himself or use an protective shield. When not under attack his life energy refills automatically and character development uses the “learning by doing” approach. The game can only be saved at hidden save points.
