Shadowgate 64: Trials of the Four Towers

In this 3D first-person adventure game, Castle Shadowgate is filled with thieves and other scum and, on top of it all, there's an evil wizard who intends to release the Warlock lord!

You assume the role of Del Cottonwood, a halfling adventurer. He becomes a prisoner of Castle Shadowgate after a raid on the caravan he was traveling with.

At first, he will only try to escape Shadowgate, but as the story evolves, he learns that the great Wizard Lakmir has a far more noble quest for him. He will be the one to prevent Belzar from releasing the Warlock Lord!
