Are you one of those people who can't get enough of some good co-op action? OutsiderXE's got you covered. This excellent mapper has recently updated his Shadow of the Xel'Naga campaign, a 7-map story for you and a buddy to play through. If - like me - you don't have any StarCraft-playing friends, you can also play through the campaign by yourself. Find the game on the arcade under 'sotx', or visit the project's page on Mapster through the link above. Still not sure? Here's a video by our resident reviewer JayBorino to tide you over.
