Not to be nit picky but didn't the health potions in Doom give you 1+ boost of health? In Gen its 5+
I dunno if it would upset the balance issue though if you were to change it to 1+
I think the Earth pistol could be a little bit faster, but again I'm unsure of balance issues with that.
Are most of the ammo pick ups true to the original? I noticed that when yu get a Combat Shotgun for Doom, you get 8 shells with it, just like the original. When you pick up a shotgun ammo box for Doom, you get 20 like the original. Are all of the ammo and weapon pick ups accurate like this? For some reason, I can't remember how many shells your supposed to get with a Q2 Super Shotgun, but it acts like Quake 3's ammo system of most weapons starting with 10 shots.
Just a bit curious
