Splinter Cell: Pandora Tomorrow Edit
Multiplayer in the Splinter Cell series first appeared in Tom Clancy's Splinter Cell: Pandora Tomorrow, where players took part in a multiplayer mode called Spies vs Mercs. In this mode, players take control of members from one of two teams that face each other in a series of objective-based modes. The stealth-based team of Spies compete against the assault-focused team of Mercenaries, both belonging to different factions, Shadownet and ARGUS, respectively. The multiplayer mode featured 3 game modes: Neutralization, Sabotage and Extraction.
Splinter Cell: Chaos Theory Edit
In Splinter Cell: Chaos Theory, multiplayer returned in a similar and improved version of what Splinter Cell: Pandora Tomorrow introduced. Improvements include ledge pulling, coop moves, and more gadgets. The 3 game modes from Pandora Tomorrow have been combined into 1, called Story Mode. It includes Neutralization (hacking computer), Sabotage (planting a bomb), and Extraction (grabbing a HDD, and reaching the extraction point.) The other 2 game modes in Chaos Theory's multiplayer was Disk Hunt which is when disks are scattered around the map, and the spies has to collect them, and Deathmatch mode which includes just killing your opponent.
