Bioware has just released a new trailer that highlights the new co-op feature in “Mass Effect 3”.

The trailer shows some of the races and classes that can be chosen, which include a Human soldier, Solarian vanguard, Quarian engineer and Krogan face puncher.

Fortunately co-op looks like it’s going to be an awesome pants party, but for those of you more interested in a solo experience, co-op is not mandatory to play in order to attain a complete ending.

“Mass Effect 3” releases March 6.
