Tom Clancy’s Splinter Cell: Chaos Theory (2005)

Sam Fisher’s third outing in the Splinter Cell series refined the stealth-based action that fans had come to know and love with a raft of new features. Sound monitoring, the ability to interrogate hapless guards with a knife and hanging upside down and snapping unsuspecting necks were all welcome additions to your already impressive skillset, while improved AI and a solid multiplayer mode made Chaos Theory one of the best offerings in the whole series.
