Alright just went through standard Doom 2 with those hilarious weapons, there is a large list:
1. All weapons can be reloaded even when magazine is full.
2. No ammo counters on all the weapons.
3. Pistols cannot be dual wielded due to the counter not registering that the player picked up another pistol
4. Dual wielded Pistols cannot be reloaded untill the magazine is depleted.
5. Pump shotgun zoom is sticky and remains active even after switchingweapons unless you manualy take it off.
6. AK-47 zoom is too sensitive.
7. Missile Launcher (from SW) alt fire costs 0 ammo to use and takes no ammo away when reloading.
8. Laser Rifle alt fire does not work (I assume it's a scope function).
9. BFG9000 fires like a chaingun if you hold the fire button down.
10. Bazooka lock-on does not seem to work.
11. Chainsaw is non-existant.
1. Improve the AUG, it is dwarfed by the Assault Rifle. I would suggest making it a burst weapon.
2. Reduce the effects used by the laser gun, it causes mass lag when firing.
Overall these weapons aren't half bad, so far my favorite is the M60.^^
Still needs improving in the animation and graphics etc. But that will come in due time. Hopefuly you can get a hotfix out for some of the above mentioned bugs.
