Walkthrough by Moonpooka for trle.net
Note: This level really shouldn't have been released as the author has placed Lara at the end of the level. So, when you begin the adventure, you are in fact at the end of it. However, you can work your way back through the level and get about five minutes game-play out of it; although there will be a few traps, pick-ups and enemies missing. You will then reach a closed gate and will be unable to proceed. Also note, that because you are playing this backwards, the enemies in each room will appear from behind. Well, we do need to have all the walkthroughs available, so even if this is a tad backwards so to speak, here we go!
You begin the level facing into an empty room (which is in fact the final room, so don't run ahead or the game will end). Turn around and head south into the next room. An electrical spark will activate in the previous room because that was supposed to be the finishing trigger.
Inside the new room, ignore the central pool (where I think there is supposed to be a shark) and head to the SE corner. Turn around, spot the large scorpion and flying bug and gun them down. Enter the south passage, avoid the hidden floor-blades and run to the end of the passage. Quickly turn around, take out the dog and small scorpion that are creeping up behind you and then head into the west room.
Make your way over the bridge and enter a room with a central pit and two lava pools. You will hear the familiar sound of harpies and they will be firing at you from the bridge room - so quickly turn around and gun the two pests down. Now head past the lava pools (don't drop into the central pit - you won't be able to get out again) and make your way into the west passage. Immediately turn around and take out the two harpies, two small scorpions and the dog that have arrived in the lava pool room. Now head down the west passage and make your way to the end. As you reach the final area, two spike-balls will fall from the top of the passage. Quickly jump the trench and arrive in a new room with a stone bridge spanning a pool.
Drop into the pool, collect some Uzi Ammo from the NW corner and a SMP from the SE corner, and then pull out of the pool and head to the black gates at the end of the stone bridge. The area beyond the gates is connected to the start of the level - but as we have played the game backwards, these gates can not be opened and we can not proceed with the level. So, sadly it must come to an end.
