Small map, something reminding legendary cs_mansion. Gates of Hell is made only for the sake of "meat", and it doesn't disappear at all. There is a mansion from which on you crowds of the zombie run. There are barricades with five six-barrel machine guns, mountains anesthetizing, a garnet, "Molotov cocktails" and cartridges. If in the beginning it is possible to constrain the zombie's flows, then when three step on the stage directly, and even four Tanks, game turn into incredibly cheerful buffoonery with the infinite shouts "Rescue me!" and fights a wall on a wall.
P.S. If you still have no achievements of Tankbusters, 101 Cremations, Man vs. Tank, Red Mist and the more so Zombie Genocidest, you is certain to the address. And if at you is also four friends with same "problems", you can safely rename a map into Gates of Haven.
