Killzone: Shadow Fall is finally going co-op in the latest DLC expansion due to be released this June.
Killzone: Shadow Fall – Intercept features support for up to 4 players and drops you into the boots of Intelligence Squad Alpha, an elite VSA team who is dropped behind enemy lines to intercept Helghast data and intel. Intercept comes with four maps based on locations from the single-player campaign and is free as part of the Season Pass. Apparently a standalone version of the co-op will come later in the year, which presumably doesn;t require the full game.
