The PlanetSide Website (thanks Planetside Universe) has word that sign-ups are now underway for beta testing of PlanetSide, Sony Online Entertainment's upcoming MMO first-person shooter. Sign-ups are being accepted for a week, so you need to apply by November 8 to merit consideration. As a prelude to this, there's a PlanetSide update describing the final stages of internal testing, and discussing plans for the external test.
