Turok 3: Shadow of Oblivion/Level 3: The Lost Land Junkyard

This is one of the longest levels in the game. The player must traverse the Junkyard to find a portal to the other areas of the Lost Land. The player encounters beings known as "Lost Ones" and most of the level deals with fighting these creatures and re-activating downed equipment to proceed. The boss of this level is called the "Opisthor", a turtle/plesiosaur mutant. This happens to be one of the easiest boss fights in the game. However, you still must fight the Lost Ones during the battle.
