Dead Space in Halo 4! What else... As a community, people can forge many different types of flood maps that have a "Dead Space theme." For example: forge a flood map on Impact and make it dark and scary. So when you play it the map will have a creepy or scary feeling to it, just like the real game! But it would be a series, if you're still understanding me, here wouldn't just be one map, many people would make different map variants for this theme to play online.
