Well, regardless of that, it’s only the exotic and heavy weapons like the Gauss/Gluon gun and RPG whose ammo isn’t lying around in huge quantities. Even if you don’t kill the Barneys, you should still have plenty of ammo left.
The ammo system in HL1 is a lot more generous than HL2’s since you can carry a lot more ammo with you and enemies drop a lot too.
In short, I still think that Barneys shouldn’t give you ammo like the HL2 rebels.
I never said I was running short on ammo, I was saying you could kill things faster with the pistol than with the MP5 and for fewer bullets 
Nor did I say the Barney guards should give you ammo, my comment was unrelated to that.
No but someone else suggested it.
I agree it doesn’t have to be to real but i think guards should be able to climb some basic ladders like ones against the wall but maybe not ones where you have to jump to or get past a obstacle.
Also a basic hand to hand seems reasonable maybe not punching or anything but maybe pushing the zombie away if its trying to get at the guard i dunno.
They have that.
