Ballistic mod for Aliens vs. Predator 2

The main motivation behind this mod is the overuse of hitscan weapons. Sure,
they are easy to implement, but they lack realism. A bullet is a material
particle, having a finite speed and a finite mass. Therefore, a bullet needs
some time to reach a target. Also the shooter should aim higher to make sure
that his bullets will reach the target.
Also you will be able to use meelee weapons also as projectiles, ie: throwing
knifes, or throwing the spear (predator), or use the disc to slash oponents
(meelee weapon).
Silenced weapons were added, and the single player weapon sets were changed so
that these added weapons can be seen in the vanilla campaigns, ie: in the
"Betryal" marine mission.
No, you do not get any character skins on this mod. The focus for this mod is
weapons, not character skins.
