What you liked
Guns feel good. Spartan abilities feel decent.
What you disliked
Map flow feels non-existent. Could just be me.
Kill-cam.
What you would change
I would widen the spread on the SMG a tad. Not a great deal, but a tad.
I would remove kill-cam OR add the option for the classic death camera. Kill-cam does not provide any strategic advantage, and in fact most of the time just serves as a way of shoving the players failures in their face, which can end up creating a cycle of negativity, as opposed to the classic death camera, which gave more of a "no biggy, you died" feel to it. Kill-cam really frustrates me on a personal level to a degree where I'm finding it hard to play games with it anymore, but.. this is probably just me, I don't anticipate 343i giving a shit about my opinion on it.
I would slow sprint speed like 5%, up base movement speed 5-10%, and make the burst-pack-thingy-thing go a TINY bit farther forward, but keep side-to-side the same. The speed changes should also make shoulder-ramming more viable then it currently is, as right now it seems rather useless (could just be me, again).
Sniper scoping is way too slow, needs changed. Feels really off.
We need more localized servers for this if it's dedicated. This game feels weird sometimes.
Gameplay bugs
Haven't seen any noticeable ones thus far.
Miscellaneous bugs
Saw a ragdoll body freak out once. Skipping killcam seems to keep the explosion particle effects on the screen for a while.
Optional - Beta rating
solid 6/10 most of the time. I'm iffy on it.
