I have a machinegun in Conquest for example that is weak, but has tons and tons of bullets, so the user can pick away at the enemy at his heart's content if he so pleases. However, since I'm limited to 255 ammo max, I have to have the gun take fractions of ammo per shot. This doesn't look good for the player, and it doesn't help the gun's image. It would be cooler if the gun actually had 800 bullets, instead of 200 and 4 shots per bullet.
My question is, do FTE and other engines support this, and how bad would it be if I assumed the user's engine carried this feature?
