So looking through all the achievements in halo 5 and something really weird caught my eye. The Spartan on the left of the image seems to be wearing some weird animal hybrid helmet with scales and even eyes and such. Not to mention the BR hes holding with a LR Scope on it. Also the AR Scope the spartan in the middle is holding…pretty interesting http://www.xboxachievements.com/images/achievements/2734/109075-hi.jpg
I think the helmet is just a decorative thing.
The attachments on the guns may be concept art for ideas that didn’t make it in the game (or maybe they did?). That’s a really cool painting.
Could be an early hint of the REQ packs. We know that guns and armor will have personalized schemes to customize your look on the battlefield. I wouldn’t be surprised if you could, to a certain point, personalize your weapon of choice to make it “yours”.
That dinosaur helmet is legit
The BR on the left looks like it has a promethian scope.

Playable dinos confirmed. Sorry, I HAD to do it.
there avaialble in req packs, the helmets a helmet varient with teeth painted around the visor and the weapons a varient of the BR, havent seen the BR before but theres a video showing all the current unlocks in the game minus a few they havent put in yet, or at the time of the video release 
Intresting…
If you want to talk about spoilers in the achievement art then dont look at the last mission achievement artwork. Very interesting.
