I've always thought it very unrealistic that enemies and allies get unlimited ammo. It makes true tactics impossible. Halo multiplayer can be fun when you exploit the fact that your enemy just ran out of ammo, but not in campaign. I think it would be awesome to see a covenant barricade, with a bunch of weapon crates that whenever an elite or grunt uses up their weapon's ammo, they run over to it and grab a new weapon. Or just grab the gun of the nearest fallen comrade. What are your thoughts on this? I think it would make halo far more interesting.
