You probably already know by now that the awesome Double Dragon trilogy of beat em ups from the 1980's/90's has appeared on GOG, but did you also know that in 2013 had one of the best OpenBor releases of Double Dragon Extreme? First released in the Arcades as both a single player and two player, Double Dragon Extreme features all the best bits from the games we've come to love, with all the punching, kicking, throwing and item bashing you could ever want!
Thankfully you have two choices, you can download the updated PC version through GOG, which is a compilation of Double Dragon, Double Dragon 2 & Double Dragon 3 in both single player or co-op online player. Or you can download the free OpenBOR version of Double Dragon Extreme! All of them are great versions and worthy of a beat em up download.
Double Dragon Trilogy is available to buy on GOG
