I would like to start off by saying that the Halo 5 beta is really fun and enjoyable, the maps are cool and fun to play on, the guns feel nice, the 'ADS' (which I was a bit iffy on) has suprised me as i found myself liking it. Now there are some things i would like to adress so let us begin!
Spartan Abilities
The Spartan abilities bring a new level to the MP but, i would have to say that the spartan ability that i dislike the most is the shoulder charge. I'm sure people will agree with me when i say that this ability is annoying more often than not and can mess you up when trying to get a kill. Example, i'll be sprint towards someone getting ready to melee them and then find mysef zooming past them with the shoulder charge because i forgot about it and they kill me. (I can't be the only person this has happened to). I suggest either taking it out completely or maybe adding something like double-tapping the melee button to preform perform the shoulder charge. I really like the thruster, it's helpful to get out of trouble, the ground pound i don't mind, though i don't think i've used it once, the slide, well i kinda forgot it was a thing until a couple of days ago , clamber is good it feels really smooth.
Killcam
Once again i feel many will agree when i say, please for the love of God and all that is holy get rid of the killcams. I read a post once that made a good point, the way halo is, 9 times out of 10 you know who killed you and how. Halo isn't like CoD where you die in half a second and have idea wth just happened. In halo you have time to see who's shooting you. I really dont need to see me getting stabbed in the face a second time when i saw it very clearly the first.
Weapons
Like I said before the weapons feel nice but some do need some tweaking. Now SMG feels really OP and i remember people saying it needed nerfing (if this has already happened, ignore this). People are saying that the AR is way to accurate but i haven't really used it much so i can't give an opinion on that. The sniper seems a lot slower then previous games so that's a little wierd.
Gametypes
So far there is Slayer and Breakout, both very fun and competitive which is always good. I'm not sure if 343i already have this planned (I hope they do), with slayer how you start with BRs, don't get me wrong love the BR but in regular Slayer you traditionally start with the AR. In Halo 3 there was Team Slayer and Team BRs, i would love to see the return of Team BRs and keep Team Slayer starting with ARs.
Minor Details
When you look at someone's player stats for example and you press 'B' to back out it make that beep sound it does after the countdown hits 0, not sure if this is intended or not but i find it kinda wierd.
Sometimes when I go to customize my spartan, he is pink and the visor is black no matter what colour he is or what visor have on.
In the game lobby very often one of the players in the lobby will be duplicted, i seen someone get dupped up to six times! Until the game starts then it's normal.
That's about it!
Apart from all the things I mentioned above Halo 5 so far is a really solid and enjoyable experience, solo or with friends. Keep it up 343i you've got something good here!
