A being from another world.
Sarge is crazy talented and dedicated, that pretty much makes of Brutal Doom the new Vanilla Doom, and that level clearly justifies a 10/10
To be honest I had a little trouble getting into a fast pace with Half Life, but once you get used to it (an thus means after 2 levels or so)it is a real drug ! You can't stop playing. Avoid this if you have a girlfriend.
On the overall the soundtrack is awesome, I found myself laughing at some moments while hearing songs that reminded me of parts of movies, especially after beating the gargantua.
Perfect.
