Here is my playthrough \o/

I love how the rooms are huge, with plenty of space to move and run in combat... but there is almost no combat :P
There's a lot of times that i enter the rooms waiting for a scrag to spit on me or for a grenade to blow up in my head, but nothing happened... there's so much space for epic fights, but there are no enemies to fight. Too many empty rooms, man. I played in hard difficulty and it felt like easy mode :(
Oh, I have to say that i love the green theme with broken walls on the first and second room, with jumping puzzles, pressing buttons and pushing pillars... it reminds me the first tomb raider game =D I wish the whole map was like this =D
