It's good. Though, a bit less meaty than previous Halos. I've been wanting to play more Fallout, but I have Halo rituals that have to be completed. Namely, struggling through a solo legendary campaign. It usually takes a long time and lots of crying.
I'm also not crazy about the micro-transactions but pretending they don't exist the online is set up pretty great.
My last main gripe is there are no cosmetic rewards for performing feats in the game. I'll admit I'm an absolute sucker for cosmetics in Halo. You could get to max rank, beat campaign on the hardest difficulty, get all the skulls, and not unlock any armor for it. I really enjoyed unlocking a hard-to-get piece and showing it off in matchmaking, but that's no longer possible. Well, except for
this one for getting
this achievement but it's not even a feat you achieve in Halo 5. It's also bonkers hard most of the human race. Ever try Halo 1 on legendary? It's madness!
