You probably don't see as many AI as usual, just about 6 enemies?
Yea, not very many of them. I was just very surprised the first time I encountered them (before I slaughtered them all
It seemed to work with my mostly blank testing map though, but that has only 3 bases and very few spawnpoints so that might perhaps affect it.
This is intentional and logical, if you can barely walk because of overweight you shouldn't be able to go prone
I would rather think that you would have more trouble standing up again than lying down.
It's no biggie though. It's not like I usually run around with guns in my backpack when playing regularly. But first I gotta explore and test stuff, hehe.
