There's five different game modes in online play- 'Sneaking Missions', 'Capture Missions', 'Rescue Missions', 'Death Matches' and 'Team Death Matches'
Missions will be set in popular locations from Snake Eater, and some new locations such as Small Forest, the Kill House and the Abolition Factory.
You can chose from the Ocelot Unit, GRU and KGB, until you've won enough matches to play as popular characters like Ocelot and Snake.
