There's a preorder only shell that some players have. It's red and I think called Enforcer. You didn't just preorder but I think it was a specific version of the game that when preordered came with the download code. If you look online there's multiple shells depicted on some sites but the only reported in-game sighted ones are the default/general shell, Enforcer, and Intrusion. Intrusion is supposed to come with the HoW dlc but some supposedly have it by glitching into a unreleased area or by some form of hacking. Edit: I meant to reply to the author, but oh well my bad. A delete option is needed.
