It seems that there's going to be a lot of exclusive armor/skins. I've compiled a list of which retailers have which armors.EB GAMES/GAMESTOP:HAZOP armor/forest skin (Worst of the bunch IMO. Simply awful. Way too much empty armor space.)Battle rifle arctic skin (While cool, it's not enough to win me over, especially when paired with that awful armor.)BEST BUY:RAPTOR armor/skin (Cool. Reminds me of Issac from Deadspace.)PLAY:Deadeye helmet/skin (Love this helmet. This is out of the question for me since I think play is a UK company (Correct me if I'm wrong.)AMAZON:CIO armor/web skin (My favorite of the bunch I love the skin, and other than the helmet, it's my favorite armor. I am liking the helmet more and more every time I look at it though. Looks like I'll be buying the game from Amazon. Shipping time isn't a huge deal for me either since I don't really care for this game as much.)blue variant (Not sure if this is real or juts one that someone edited)Bulletproof emblem (I couldn't care less for either of these emblems, but there's no harm in having them.)Spartan emblemMICROSOFT STORE:GUNGNIR armor/pulse skin (It mildly interests me, but Microsoft store is too much of an inconvenience for me.So you can change the color of skins and I'm fairly certain skins are not tied to armor.Also, on the halo bulletin, there's a description of how the new weapon the railgun works. It basically sounds like a guass cannon. Insta kill, half the charge time of a spartan laser, it makes vehicles bounce, roll, or swerve (think bruteshot or concussive rifle), no travel time, and no zoom. (all of this is subject to change BTW)~U_K~
