Having played the alpha and beta I found that the pvp was enjoyable albeit with some issues. My experience thus far on the actual game is so depressing. It feels like Bungie have just amalgamated all of the worst concepts of shooter design since CoD4 in one horrid mess. I cannot believe this studio made Halo.
The supers are horrid. The time-to-kill is far too low. The netcode feels subpar. The new maps, so far, really haven't impressed me. Simplicity is beautiful in map design, and these maps are exactly the opposite. Too much crap all over them, too many routes around them. You end up in so many fights where you're dead before you even have a chance of returning fire, and moreover, far too much of the fighting is going on at close range where you're likely to be killed by an endless list of one-hit-kill weapons and powers.
I'll keep playing, but right now I feel really down on it. I would love something slower paced.
