5 stars: An unbeatable mobile game. This game plays great, looks great and has a ton of replay value. The controls are simple, making the game easy to learn but hard to master. Even if you don't like Halo, you will love this game. The only improvements I recommend are info on what all the medals are and volume sliders. Additionally, when a level is completed on Legendary, the menu (where you select your mission) should show Mythic by default.
5 stars: Simple, addictive and fun. If you're having trouble with the controls, give yourself a moment - when I started, I kept missing the second jump in arcade mode. Now I can do it pretty easily. Lots of customization, including a bunch of colours and three different helmets right from the start. I would definitely recommend this to a friend. Or you.
3 stars: I had this on my old phone when it was in it's starting stage. It ran nice and smoothly but now with every time the spartan takes a step the camera moves with it so it just 2 frames a second but as soon as I jump the screen scrolls nice and smooth again. 3 stars because I know how it should play but knocked 2 off because of this issue.
3 stars: Love the game, fun, and a fantastic way to spend a night shift. My ONLY issue is that it has an issue where it seems to skip a beat every 10 or 15 steps and freezes/hiccups for a frame. I've also noticed it does it with the brute shot and shotgun. Once the frame issue gets fixed or at least looked at it would be an auto 5 star ...
