Killzone: Shadow Fall expansion, Intercept, adds online co-op in June

Killzone: Shadow Fall developer Guerrilla Games will add online co-op to the first-person shooter next month with a new expansion called Intercept, the studio announced today.

Intercept will be available free to owners of Shadow Fall's $19.99 season pass, and Guerrilla will release a standalone version later this year. At launch, it wil include four different maps based on campaign locations.

The expansion supports up to four players, with the team playing as members of an elite group known as Intelligence Squad Alpha within the ISA's Vektan Security Agency. Intelligence Squad Alpha's mission is to intercept Helghast intelligence missives and send them back to VSA headquarters; the co-op mode is a wave-based arena combat experience in which players are attempting to hold off Helghast forces for as long as it takes to establish a hacking uplink and send the data back to home base.

Four classes are available in Intercept: Assault, Marksman, Medic and Tactician. They must work together to increase their Team Score, which measures how close they are to setting up the uplink. Defending uplinks from the Helghast raises that score, as does personal performance — kills, ability uses and uplink recaptures. But every time the team loses an uplink, or a player dies and respawns, the Team Score drops. At some point, it'll get too low for people to respawn, so when everybody dies, it's game over.
