Zax: Alien Hunter Windows game

When the alien hunter's ship is shot down by an unknown attacker on the surface of a planet, there is no other option for Zax and Zelon to get the ship to planet in order to survive. Zax soon encounters the force behind his presence here: Om, the leader of an army of robots that enslaved local primitive tribes of Korbo. Zax, all while collecting the minerals he sought for, has aligned himself with the Korbo and started a crusade against Om. On his way through the jungles, temples, caves, and mines, he is aided by Korbo leaders, like Mindaza, Valeth, Butu, and Partha.
