Starbreeze and Behaviour Digital's multiplayer horror effort, Dead By Daylight, has sold over 270,000 copies in its first week, recouping its development costs in just seven days, Starbreeze said today.

The tense cat-and-mouse title, which sees one "killer" player pick off four survivors, has cemented itself at the top of the Steam charts since launching on June 14. 

Bo Andersson Klint, CEO of Starbreeze, believes Dead By Daylight has vindicated the publisher's decision to pursue "spectator friendly" projects. 

"We couldn't be happier to release Dead by Daylight as our first publishing partnership together with Behaviour," said Klint.

"With this launch, we've proven that the concept we developed with our own Payday franchise can be replicated and utilized for other games.

"Taking the game to different events and seeing it on the top five most streamed titles on Twitch has been a thrill and a real ticket to the games success as a spectator friendly game."
