Double Dragon Trilogy, publisher DotEmu's compilation of the original three Double Dragon games, is now available on iOS and Android for $2.99.
The company announced the existence of the bundle in October. It comes with Double Dragon, Double Dragon 2: The Revenge and Double Dragon 3: The Rosetta Stone.
You can opt to play the beat-'em-ups in Arcade mode (going for a high score through the entire games) or Story mode (unlocking stages and achievements as you progress through the games). All three offer two-player support via Bluetooth as well as customizable controls, and a choice between the original 8-bit soundtrack and a remastered one.
Three difficulty levels are available: "mobile," which is balanced for touchscreen play; "normal," which is similar to the way the games played in the arcade; and "expert," a more challenging setting. The Android version supports most gamepads, and according to DotEmu, the trilogy will soon support iOS controllers.
You can check out the Double Dragon Trilogy on Google Play or in the iTunes App Store.
