Tomb Raider Seth Strikes Back V3 (TRLE) Author Walkthrough - Level 4 : Lost Tomb

Author walkthrough for Tomb Raider Seth Strikes Back, Level 4 "Lost Tomb".
Note: I forgot to update the video before uploading, the room at 31:24 has a sightly different design in the released V3 (to avoid the flickering you can see there) but the point and way to solve the puzzle stays exactly the same as in the video.
