Serious Sam: The Second Encounter: Tips And Tactics
In the Mission The Citadel I found a powerful bonus! After you jump out of the room with gears that rotate in water (after the secret number 9), we fall into the next Zavaruha, and how it is found, we defeat. After the glorious battle, turn to the place from which we jumped out (there will see more primitive clocks), turn to the right and see the corner of this locality, shed, it does not matter, pinched on the door two or three times. If the door does not open after that, try to run for this pawnshop, there in the dark corner (directly in the depths itself) will pick mega and midnight megasex. Good luck!
