Deniable Ops co-op mode detailed for Splinter Cell: Conviction 

Splinter Cell: Conviction's co-op offerings will add an extra 5-6 hours of backstory, giving two players an opportunity to explore together, says Gamespot.

There two modes are called Prologue and Deniable Ops.

The first bit, which we already told you about, puts a pair of spies with distinct backgrounds and personalities into the Conviction timeline, while Deniable Ops will present four different ways to sneak around ending the lives of your enemies.

While Prologue will focus more on story, Deniable Ops tests your stealth skills in a variety of ways with modes like Hunter, Last Stand, Infiltration and Face Off - which pits players in a versus match-up in an AI filled area.

Through the link there is a vast hands-on with the co-op mode for the game, which you should definitely take a gander at.

Game's out next month.
