Theseus: Return of the Hero is the logical sequel to Alien Shooter.
Despite all the human efforts to resist monster invasion, the blood-thirsty creatures keep occupying new territories. Theseus, the hero of this game, arrives in a small European town and gets into the very middle of such a battle. Of course Theseus immediately joins the fight against the aliens. The game features 10 missions, mostly taking place in open spaces, lots of playing locations (forest, village, highway, city battles, etc.), six types of weapons, ability to upgrade the main character, and an inventory shop where you can buy the newest equipment between missions.
