I fell off of the mountains in the first chapter of turok evolution and died after all these years...
When speed running Turok 2, in Port of Adia, when preforming the water speed boost glicth in the second water puddle, which leads to the first child, I can hardly ever make a successful jump onto land for some reason. The hit box is in my way.
The first time I had played Turok Evolution in 2003, when we rented it from Blockbuster, I made it to the second area where the brachiosaurs are in the water, and couldn't figure out how to get to the next area. So I gave up and returned the game. Little did I know that I would come back to that game much later as a huge fan.
