Co-op DLC is coming to PC (and Mac) game Krater on October 23, it has been confirmed by developer Fat Shark (they're pretty busy right now, War of the Roses goes on sale today).
"The co-op DLC will be available on October 23, 2012 via Steam. The download will be free, and will also include a large number of updates to the single player content." said Fatshark CEO Martin Wahlund.
"Shortly thereafter there will also be new character DLC's with some nice vanity flavor to them if you want your character to look the best when playing the game."
Producer Robert Bäckström then added: "The game experience from day one to now is very different. We have listened to the player feedback. There is a lot things adjusted and added to the game. If you played the game at release, and play it on October 23rd, you will get a whole new experience."
