In the Vidoc at around 2.55 after the introducing of the Spartan 4’s just after we see the in game skeleton we see at the top left cornet of the screen there is a Spartan 4 crouching backwards with the BR being held left Handed. This scene is with Franky talking on the right side. So I wonder if there will be a more interactive customization where you can choose if your spartan is left or right handed. This is a nice touch by 343 that shows that they care about the left handed community and how much thought to detail they put i their game.
Or better yet, maybe you could switch hands the way real marines do so that you don’t have to expose yourself on right hand corners.
i’m 99% sure they just reversed the image.
