Double Dragon > Sega Game Gear

The original badass beat em up is here in the form of Double Dragon! Take the powerful Billy, or his twin brother Jimmy Lee on an epic adventure through the gang territories of the evil Black Warriors to find Billy's girlfriend, Marian, who has been kidnapped. Cruise the gang-infested streets looking for trouble, beating the hell out of all the dodgy gangsters and staying on your feet long enough to find Marian and save her.

Sticking with the perfectly even number, we have another four awesomely popular titles from this great series. If you're interested in more Double Dragon action then you'll want to take a shot at Double Dragon 3 - The Rosetta Stone, Double Dragon V - The Shadow Falls, Double Dragon II - The Revenge and the amazing Super Double Dragon!
