I hate this game.
I didn't even bother going past the first level. (I might have liked it more if I played through it, but the first level is just horrible, so I didn't bother going on.) So I'm like dropping down in a pod. It's all cool and stuff. I crash land into a city, get ejected from the pod. (That's about as cool as it gets for level 1) Once I'm on the ground, it tells me to turn on my visor. I did, it's a pretty cool feature. Now here's the crap part. It doesn't tell me what to do next. So I'm here running around the city 50 times. I see some grunts, kill them. Repeat. You keep doing that over and over until you get a headache. Then you ask a friend to finish the mission for you. I'd rather do homework then play the same stuff over and over. In fact, that's what I did. It should at least give me hints every 5 minutes of what to do instead of having the player running around until he gets a headache. Now my friend finds this telephone. He tells me I have to find the glowing objects. Well that's kind of hard, because the glowing objects glow yellow, and my screen is practically the same color. (Yellowish-green) Then my friend tells me I'm supposed to download a map. A map?!? I didn't even know what I was supposed to do for the objective!
This game was a huge disappointment, probably the worst of the Halo series. It didn't live up to it's expectations.
IMO.
