If you haven’t already downloaded the Killzone: Shadow Fall multiplayer client, what are you waiting for? The multiplayer portion of the game is free-to-play this week, even without a PlayStation Plus membership. The multiplayer mode can be enjoyed with no limits this week, starting today at 5PM PST (1am GMT, on Tuesday 4th March).
The promotion is to promote the game and the new maps that are coming to the game as part of this Week’s PlayStation Store update. The multiplayer client can be downloaded ahead of the starting time later today – just make sure you prioritise the multiplayer portion of the game first. The single-player mode won’t be playable unless you own a retail copy of the game.
