This map is excessively hard. If you try it you should know a few things that will help you.
Walls marked with a yellow "S" contain guns on the other side, you can enter ducking.
There are 3 death traps and the only hint you have is a tiny edge on the floor, try to get The Minotaur into the trap to kill it.
Red lasers Kill you, avoid them.
In the Crouch maze, in the upper right corner you will find a little man painted on the wall. The floor can be broken. There you will find a secret area, go with a lot of C4 and be away before detonating, the blast can hit you easily
