Assassin's Creed: Revelations (PC) vs Tom Clancy's Splinter Cell: Conviction - Deniable Ops Insurgency Pack (PC)

When a man’s battles have been won and his enemies destroyed, what then? Where does he find purpose and meaning? To find answers to these questions, Ezio Auditore will travel east in search of the lost library of the Assassins. In Assassin’s Creed® Revelations, master assassin Ezio Auditore walks in the footsteps of the legendary mentor Altair, on a journey of discovery and revelation. It is a perilous path – one that will take Ezio to Constantinople, the heart of the Ottoman Empire, where a growing army of Templars threatens to destabilize the region. In addition to Ezio’s award-winning story, a refined and expanded online multiplayer experience returns with more modes, more maps and more characters, allowing you to test your assassin skills against others from around the world.

On the 27th of May, the first official DLC pack was released for Splinter Cell: Conviction. The Insurgency Pack is available for 800 Microsoft points and will get you 4 new levels in Deniable Ops mode.
Multiplayer mode in Splinter Cell: Conviction involves both split screen and system link (Xbox 360), and online cooperative mode, plus a Deniable Ops mode. Deniable Ops mode involves 4 multiplayer modes that pit the players against AI in game modes such as Hunter, Infiltration, Last Stand, and Face-Off. Face-Off is the game's only actual competitive multiplayer mode, as it features the ability to kill the opposing spy. Hunter, Infiltration, and Last Stand are also singleplayer and do not always have to be played with a human partner. The game does not contain the critically-acclaimed "Spies Vs Mercenaries" mode featured in the previous games of the series.
