Also idk if you are aware of this problem but your map is very unstable in terms of performance, lots of fps drop. var is 2.35msec, sometimes way more (most of other map var is around 0.30 / 0.40msec).

The problem should be fixed in the latest update

If you change the roof from func_brush to func_asw_fade there's a setting to ignore grenade collision for grenades that spawned below the roof

delet roof i good solution =)

Hello and tanks you everyone for your comment.

I have already studied the problem of the grenade launcher, but for now there is no solution that suits me

there is issue, grenade luncher cant be used inside buildings bcs of roof :p

killing lots of bugs, sign me up!

I'm loving this map!

Am glad that you guys still plan on doing more maps for Alien Swarm. Namhuman was an great addition to the game and i hope seeing more of yall work on here

Cool
