Oh yeah. Been playing Reach a lot lately to get back in the swing of things.
[spoiler]4 sucks so bad that I don't even want to practice on it, it's not even a challenge[/spoiler]
I don't know why, but I will be playing as Osiris. It brings a sort of energy to the game that we've seen in the trailer, and I've seen some gameplay which had arbiter talking to Locke on comms.
