Sony has just announced that the Killzone Mercenary beta will open up to PlayStation Plus members on August 21st, available after the Store update on the day I assume.
For every other Vita owner the beta will be available from the 28th of August, a week after the initial Plus rollout. However, it’s different if you’re in Germany where only Plus members will gain access to the beta, though a reason hasn’t been stated on the PS Blog.
The beta will run until the 3rd of September, which means two whole weeks of shooter shenanigans for Plus people. Of course if you were one of the lucky few who already had access to the closed beta you’ll have a whale of a time taking out newbies.
If you haven’t already seen it you can watch our preview of Killzone: Mercenary here.
