How to add effects in map?

snip

env_particlecontroller

Or other various env_ stuff in the entity tab, but i think what your looking for is env_steam.

thanks. now, how do i add a episode one zombie igniting flare into my map?

Don’t know that one, sorry. But try interlopers.com and half-wit.com

I think the above post mean halfwit-2.com*

There isn’t a zombie igniting flare

You just give the zombie an input to ignite when you push a button

“Zombie-que” Achievement unlocked!
