If you can’t wait for one PlayStation 3-exclusive beta to kick off, just get into another one, which in this case happens to be the SOCOM 4 one. Sony and developer Zipper Interactive have let loose info on when and how to get into it.
The beta will begin later this month; PlayStation Plus members will be the first ones to be eligible for it on March 22nd. On the 29th, those in possession of the voucher included with Killzone 3 copies will begin to have access to the beta as well. The rest will have to wait for April 4th to get into it. The beta ends on the 13th.
Keep in mind these dates only apply for North America. We’re still waiting on details for other regions.
