Double Dragon, the original co-op beat 'em up franchise, is still going strong after nearly 40 years. Double Dragon Gaiden is a big hit, River City Girls 2 is getting Double Dragon DLC soon, and now a 3D entry is coming. Arc System Works recently revealed Double Dragon Revive in a Japanese magazine, showing off some character artwork and screenshots. We don't know a lot about Revive yet, but we fully expect it to support 2-player co-op.
