The Co-Op campaign follows four characters, all working on a cruise ship to redeem themselves after leading sinful lives, when pirates attack. The captain of the cruise ship grabs all of the money and takes off, and it was him who led the pirates into attacking the cruise ship. It's now up to Callum, Leonard, Mikhail and Tisha to track down the captain and get their money back.
There are two options when you click on the Co-Op option on the main menu. The first one is Online Co-Op, which allows you to play with up to three other players online. You can level up like you do in Multiplayer, and it's shared with that aspect. The other option allows you to play Co-Op offline with one other partner, and XP earned is not applied to your Multiplayer portion.
| NOTE |
| The majority of the Co-Op missions usually entail you going from objective to objective, killing all of the enemies in your way. How many enemies and which kind you encounter usually depends on how many players you have in your group. |
