I was thinking... Let's make alternate fires for weapons!
Basicly, on the Weapons Menu, there would be an option to the left of the weapon name that said "Alt." or "Alternate". The alternate would make it so you didn't have a secondary, and when you hit change weapons, you would switch to alternate fire.
For example, the Spas might have an automatic funtion, but with 1/2 damage. Or the AUG could have semi-automatic fire with a small scope (AUG has a scope in real life, just who those who don't know) and increased damage. Maybe the AK could have burst fire?
Feel free to post ideas.
