First off I would like to say that for years now I’ve been wishing Halo would go back to its roots. Halo has finally gone back to its roots. I will admit that the first few games of the beta were terrible. I hated the controls and I wasn’t used to the changes. After a few games I changed to the Green Thumb control setup which is basically like COD and I really like that setup but I’m still getting used to all the new features. Halo 5 is very balanced IMO and I love the new movement mechanics. I finally feel like teamwork is important because of the same starting load outs and the Spartan callouts are important. The AR and SMG finally feel powerful enough to win close quarters gunfights but not to OP to where I can spray them from long range. The maps are balanced and the movement feels very natural on them. I don’t understand the complaints about the Spartans fist bumping(haters and trolls gonna troll and hate). The game looks and sounds amazing. The main issue I have is the controls don’t feel natural to me yet. I’m not a fan of the spartan hub completely, I wish there was a simple KD spread and more stats to go over similar to Black Ops and Advanced Warfare. Also the hub is a bit dark and my Spartan doesn’t look as vibrant as I would like; the textures are pretty bad too, especially on the Nightfall armor. I would like to be able to customize the arms and legs like in Reach also.
TLDR: game is great, it’s still a beta so it can get even better, and don’t give up after your first few games.
Also so if my spelling is bad or my post is a rambled mess I’m sorry, I typed it all on my phone 
another also is that holy crap I had a 26 kill game perfection and it was the most fun match I’ve had in years!
