OH MY GOD! THEY KILLED MARIAN!

More of a remix of the first arcade game than a completely new adventure, although this time Machine Gun Willy decides to make things way more personal for the Lee brothers. Also, there's no exploitable elbow this time, gotta take this game's sadistic difficulty head-on.

Unused Graphics

With the exception of the Lee brothers, Jeff, and Willy, all of the returning characters from the first game were redesigned in some form or another. While there are some leftovers from the first game that were left unchanged, there are also redesigned sprites for this game that went unused as well.

	Marian's face on all of her walking animation frames was redrawn, but only her standing pose (the first frame) seen here is used. Unfortunately for her, she gets shot by Willy in the opening sequence before getting a chance to go anywhere.
	Williams sitting atop some higher ground. In the first game, he sat atop trees on Mission 3.
	Rowper's knife/dynamite throwing animation, an ability he had in the previous game but lost in this one.
	The square-haired strongman (named O'Hara in the Genesis version) never uses this double-hand slap technique, much like the bald Abobo from the first game.
	O'Hara breaking through a wall. His head-swapped counterpart, Bolo, uses this animation sequence at the beginning of Mission 2.
	Jumping animation frames for O'Hara and Bolo. In the first game, Abobo uses similar frames when he jumps down from a tree trunk in Mission 3.

Unused Music

ID	Track	Notes
05		Located between the tracks for Mission 3 and 4. Due to its infinite looping, it might've been a stage track.
0E		A short, somewhat happy-sounding jingle. Bizarrely, this does play in Double Dragon Trilogy just before the final boss emerges from the shadow.
0F		Another short music track. Judging by its tone, it may possibly have been intended for when the final boss fades away upon defeat.
58		The intro sequence for the final fight plays this eerie ambient track, which is programmed to run for just over 4 minutes (when every audio channel syncs up), but only the first 10 seconds are heard in the actual game before the fight starts, leaving the rest of the track unheard. In Double Dragon Trilogy, if the music setting is changed to "8 BITS", the actual battle theme will not play when the fight starts, and this song will continue playing, allowing it to be heard for longer.
