To znany problem, wiem, że drzwi mogą się blokować w 2 misjach. Zacznij całą etap od początku, u mnie pomogło. Innej metody nie znam.

The answer is easy: You failed to pick up the correct key, which can be found ONLY upon the corpse of the guy that uses the swimming pool. The key you pick up in the room is NOT the one that opens the door where the actual bomb is (the bomb case is in the room with the key, note, gun, and Do Not Disturb sign, where Gusano Gordo is taking a shower in those stomach-wrenching briefs).

The Master Key also does NOT open the doors to the showers, sauna, and pool…so, it's not really a master key, is it?

The first time I played that level back in 2009, I experienced the same problem.
