There seems to be a trend in MMO shooters lately. Both DUST 514 and Tribes: Ascend have offered pre-purchase packages, including benefits from currency to bonuses, and more importantly; beta access. Players intending on playing the game have an opportunity to both nab some exclusive items and gain access to the game early.
For $39.99, Sony Online Entertainment is selling the Alpha Squad package, including $40 worth of Station Cash, exclusive decals and titles, as well as instant beta access. The offer also includes twelve weapon unlocks. This package cannot be purchased with Station Cash. You are not sent a key, so access cannot be transferred.
While early access starts now, it is important to remember that Planetside 2 is still a long way from release. There will be regular server downtime, character wipes, and a whole lot of bugs and balance issues.
