zombie apocalypse (may cause lag)

READ DESCRIPTION
yep its another zombie apocalypse save in gm_bigcity but this time i added stuff almost everywhere in the half of the map, such as zombies, debris, dead bodies, driveable vehicles, allies and stuffs

download the addons i added on the list if you see errors

if youre experiencing lag, type "host_timescale 0.5" it should slow down your game a bit so you dont freeze too much.

if theres any required addons that i missed on the list, pls warn me in the comment section, its a big save so i could have forgot something

games required to be mounted: left 4 dead 2, left 4 dead 1 and maybe counter strike source
