Splinter Cell: Conviction’s upcoming expansion, entitled Conviction Insurgency Pack is set for release on 27th May.

The DLC should cost 800 Microsoft Points on the Xbox 360 but we’re yet to learn how much it’ll be for PC.

The add-on features new bits for Archer and Kestrel on co-op mode Deniable Ops with a brand new set of maps. There are four maps included in the pack made up of a New Orleans cemetery, the San Francisco docks, a Portland prison and a hidden research complex in Salt Lake City.

There are a set of new Achievements for the game, which could award you a further 250 gamerpoints.
