Released 1.1 with a bunch of changes including:
- group up into squadrons (no friendly fire against squadron mates in PVP zones)
- when you pick up a gun your current gun drops, so you can pick it back up if you don't like the new one
- a lot more possible weapon variety
- bunch of other stuff in this thread:
