It may be the only co-op holiday in existence and there's simply no denying the "oldest form of co-op," but it seems a lot of games are hopping on the love wagon this Valentine's Day. Valve's Portal 2 is the latest title showcasing its red hearts with a brand new Aperture Science video about the holiday.
The video is littered with pop up style facts regarding popular V-Day gifts like chocolates, diamonds, and flowers. But the most important fact is the one about "cooperative portal testing." Sounds kinky, I predict a Co-Op Couples column.
