Ninja Gaiden Sigma 2 is a sequel to a popular PS3 title scheduled to release everywhere before the end of this year, and this game is set to get even better with a new feature that has been announced: Co-op!

The co-operative mode called Team Mission is an online add-on that will offer a selection of special missions outside of the main story for you and one other person.

The game will even let you choose whatever mission you’d like to do and what characters you want to play as.

If you dont have a connection to the internet – which lets face it, if you’re reading this then you most likely do – or if you’re scared of other people,  then you can play with the help of the CELL as your friend.

Every mission is constructed so that they can last a whole sitting, but of course it depends on how good or bad you and the CELL your friend are.
