I hope there is no destructible environment in halo 4. I wouldn't mind the rocks and ground being torn up, but not the acuall pieces. What would be the point of a wall, or a building if some guy in a banshee could just knock it down. It works in Battlefield, but I don't think it would work in halo. But I do agree that bullet holes should show up on forgeable pieces, not just the map itself. And it would be cool in forge to set an object as destructible, but I think the built in maps, at least, shouldn't be destructible. Only community maps. But I also wouldn't mind a destruction playlist with destructible environments.
