There are several gungame mods. The deathmatch gungame with instant respawn. I don't like this. What I like and how I think it was on the old server: If somebody dies, he will only respawn if his killer gets killed. This is far more interesting than the deathmatch mode!
P.S.: Do you know the name of the cs_office-like map we had on the old server? The other one was de_dust_pcg, but I forgot this one
P.P.S.: I hate simpsons maps! Really!
I think you mean dm_industrial_gamma
