Human spawn on opposite sides of the zombies. Humans start with plasma pistols and only a shotgun and pistol for the whole pack of people. they must move to the sewers to gather more weapons. Weapons and most scenery NEVER respawn. you've got 3:00 minutes to survive. Some where there is adrenaline shots (custom power up) laying around. zombies move a little faster and have radar. Humans have no radar. enjoy zombie spawn in front of the guns firearms the water and supplies thats all you get the map the game type
IDK the map has been done a bunch of times before maybe you can add more ramps and obstacles actually make it feel like left 4 dead but all still DL and check out the map and gametype to see how it plays.And heres a tip you should add hidden weapons lying around sorry if you did but if you have a large party it would really help out.
It looks like only very few things have been forged and put into the map. The game seems very plain and you did not really make a plan for it. The name is too over used already. Try putting some building-like structures and change the name. Also don't put too much stuff in one place.
