Video: Tomb Raider: Underworld - Thailand Final Room Glitch
A glitch in the Nintendo Wii version of Tomb Raider: Underworld near enough prevents players from actually completing the game.
The glitch can be found near the end of the Coastal Thailand level. Luckily, Eidos is aware of this and has some solutions to the game completion preventing glitch as detailed on http://forums.eidosgames.com/showpost.php?p=900077.
Below is a video of it courtesy of campstuff92 via YouTube. The video's caption reads:
This is how you do the final room in the Thailand level of Tomb Raider Underworld for Wii.
I posted this video because a lot of people seem to have a glitch where the lever that opens the underwater door is not there, and a guide to where the lever would be.
