The assault rifle lacks damage, it takes more than a clip to kill anyone. In most cases I have to switch to my magnum to finish the kill off.

Also, I do not like the fact that we cannot create custom controller layout.

I find that there are not enough weapons, or health packs on the map. I have to go around scavenging around for supplies.

I outright hate the SWAT mode. The killing is too instant to be fun, and it feels like there's little strategy involved due to this. The mode feels more like unreal than Halo, (only you kill/die faster). Granted this mode may be more enjoyable if the lag wasn't so bad.

I want to note I'm an avid Halo fan, and this is the only game type I've ever disliked. Also, I miss the battle rifle - the replacement gun doesn't 'feel' or control as well.

I don't know if other people experienced this but crouching in mid-air seems to prevent you from receiving fall damage when...well falling from a great height.
