The Killzone Shadow Fall Weekend Warfare event kicks off on December 28, but Sony is allowing PS4 gamers to download the game now to allow for slower internet connections.

The four-day multiplayer trial offers players the chance to try out the game's 24-player action, including Warzone customisation. All progress will be carried over to the full game.

Some users are reporting that when activating the download they are given the option to choose between the single player and multiplayer components, although access to the single-player campaign once downloaded hasn't been confirmed.
