The third map pack for Killzone 3 will release on the PlayStation Store on June 21 for $4.99. For the price of admission, you get four maps, two of which are remastered from Killzone 2. One is Tharsis Depot, while the other is Radec Academy, whose changes you can see in the video above. Anyone who spent a decent amount of time with Killzone 2’s multiplayer probably lost a lot of hours in Radec Academy, so it’ll be great to see how the new one stacks up. You can head over to the PlayStation Blog for three additional trailers showcasing these retro maps.
