Some things I've noticed while playing, it definitely is still buggy. There have been a number of major Arkfalls (the four or five Arkfalls in close proximity), mostly Hellbug exterminations and having to deal with Hellbug Matriarchs and Hellions, that ended up becoming buggy and either the crystals disappearing prematurely or we wouldn't be able to kill the Hellion.

Last night, there was one we were dealing with a Hellion, holy shit. I ended up running out of ammo, it wouldn't let me pick up new ammo, wouldn't let me reload, wouldn't let me switch weapons, there were dozens of us just running around meleeing Hellbug Warriors that were stuck in place around the Hellion. Ended up glitched and bugged all to hell.

And the 360 can definitely end up pushed to it's limits during Arkfalls. Once or twice, in a densely populated area, there have been a couple Arkfalls where it seems like 100+ of us are there attacking it, and my god do the frames per second drop to shit. Sitting there trying to shoot, the screens lagging so badly, I had no clue if I was even hitting what I (thought) I was aiming it.

Still a damn fun game. It has been years since I last played an MMO and this certainly makes up for it.
