It's also a good time to be a shooter fan. Defiance has started its first bit of testing complete with a new FAQ, DUST 514 is opening the beta gates on January 22nd, and Warface is in closed testing as of now. There's also a new trailer to ramp up excitement for Path of Exile's open beta coming on the 23rd.
Need more potential games to test? Jump on past the break to see the full list, and let us know if there's anything we missed (or a game that sneakily added a cash shop) in the comments!

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.
