- 14 missions you can only play in co-op
- can take up to 10-30 minutes for each objective
- each of the four mission types relies on who sends you into the field
- Charlie Cole, Kobin, Grim, and Briggs each assign you different goals
- Example: Grim wants you to retrieve information without alerting a guard
- Briggs is the other Splinter Cell in the field with Sam
- customize Briggs’ suit and loadout to the same degree as Sam
- you and your co-op partner can roll into the field with wildly different gear
- mark-and-execute functions differently in co-op than it does in Conviction or Blacklist's campaign
- guys with helmets might require a double-tap to the head
- some missions have unavoidable action sequences
- spies can cloak, monitor enemies through wall
- mercs can track their enemies with a motion tracker and inject adrenaline to counteract incoming fire
- spies thrive on instant-kill melee strikes, although they can pack effective guns
- gas grenades, EMPs, flashbangs, explosive mines, the sticky cam, resupply packs, and smoke bombs all return
