First off, let me say that I’ll be talking about the way weapons are stored on your character visually, not weapon placement on maps. One of the reasons I love Halo is for its customization and its awesome graphics/models. I loved when they added visible weapons on your character in Halo 3, and I think it should be slightly improved upon in Halo 4. I’ll be using (poorly made, quickly thrown together) images throughout to help visually explain my point.
I’ll start by sharing ideas for weapon placement. I think that all weapons, whether big or small, should be stored on your back vertically, off to one side; not diagonally in the middle as they are now. A perfect game I’d like to use to reference this in the Rainbow Six Vegas series. Say if you’re holding a BR and an AR, they would be on your back vertically. In my opinion this gives it a nicer look, and place for another weapon to be when you holster your weapon (a feature which I will explain in the next paragraph). Even small weapons like SMGs and Spikers should be put on your back, but placed higher up to allow a believable reach-distance.
Now onto the ability to holster all of your weapons. There should be the ability to holster your weapons in custom games and forge. This would be great for machinima, and casually hanging out on a map talking with friends. It should be able to be done over Xbox Live, but only in customs and forge. It should be something simple like pressing right or left on the D-pad.
I don’t think either of these features would be “wasting” dev time or disk space. The game has been in development for 2 years already and has 1 more year to go, so I’d believe 343 knows exactly where they’re going with their time. Also, with Microsoft’s new disk format, which Halo 4 will most likely use, there will be an extra GB on the disk for the developers to add new content. So I don’t think 3 animations would hurt that (Idle standing, walking, and running with guns holstered). Also, there are people who strictly play Halo for forging and playing custom games with friends, so this feature would add a perfect casual touch to the game.
