[MAP] Zomb_Cool_Surv - a hard Zombie Survival

Its very hard but if there are 4 players on a server its very fun!
There are some tricks u have to use:
-Everybody at his stage
-Hook the ceiling near the black where they spawn and shoot
-If a MEGA comes go to the very right there'S a high stage where its possible  to kill him easily (Friends help shoot)
-They will go at stage 4 if they come through so hook the ceiling at the right after the powerups und shoot with grenade
-The best one should go at stage 4
-Good luck!
