That's right, no func_breakableWrong. There are breakable boxes that also explode. I can´t remember where exactly they are. but I think It´s the second or first level of the second episode. I am sure that there´s one in the first level of the first episode, and also scattered around in other levels.
There are rotating stuff, but I´m not sure that they are useable doors. :/
BTW: nice level Admer!!, I am now playing Quake Scourge of Armagon and I love to see that Quake´s still alive.(I play Quake1, Quake2, and their expansions once every springtime along with the first Unreal )
