I wish UDMF would be used,and zdoom/gzdoom functions such as thing spawn would be utilized for simple, easy traps,that would take up no space,without needing anything to open,or teleport from elsewhere! You walk over a line,or pick something up,and enemies spawn out of nowhere!
Then cacos wouldnt come up the fences anymore. I would dislike sound blocking due to this too.
I like them invading too! makes for good battle!
sounds like Doom needs a better ai 
sgt Mark? optimize it further please xD
On the other hand it isnt that stupid to guard the entrance though.
They just should stop to infight and shoot against each other xD
So true! I would not mind smarter enemies,that would move fast,take cover, work in small combat units,and even throw grenades at you. I wish they threw grenades more often in project brutality. Also wish you would pickup grenades more often from dead enemies in that.
