Today is a good day! Space Marine's Exterminatus Mode launches on the PS3, PC, and Xbox 360*. That's the promised four player co-op mode. The best thing? It's absolutely free. Players simply need to fire up a copy of Space Marine, and then they "will be prompted to download a small update which will add Exterminatus to the menu system and guide them through the add-on content download." Easy-peasy. Check out the video to see it in action!
You can see all the details on the co-op mode here. We'll have a full Co-Op review of Space Marine soon!
*As of this writing, Exterminatus was live on the PS3 and PC. It should be up on the Xbox 360 shortly.
