Betawatch - PS2
PlanetSide 2's closed beta test kicked off earlier this week, as did MechWarrior Online's early access beta, though the free-to-play MWO is quick to discourage traditional beta terminology. RaiderZ likewise joins the closed beta roster; we put together a video preview of the game for those of you not yet in on the test.

We also learned that Neverwinter will be playable at Gamescom next week, though there's no news yet on that game's upcoming beta. (People keep asking. Now you know what we know.)

Finally, Guild Wars 2 ran two more impromptu stress tests this week for people who don't work during the day. Thanks, GW2!

The complete Betawatch roundup is just past the cut!

Open testing phase
Massively considers a game to be in open testing if it has open, public signups and plans for a server wipe before its official launch. Self-described "open beta" MMOs that have soft-launched with functioning real-money cash shops will not be listed.

Closed testing phase
