I remember playing Double Dragon Advance all the time in 9th grade! I wish I still had the game. I still remember the noises the characters made whenever they died!
And they combined elements of other Double Dragon video games. On the roof of a moving truck from “Super Double Dragon” and this in-game tune from Double Dragon II - The Revenge”
I hate them. 1v1 they are really easy but when they come from all sides with their hard hitting combos they are a nightmare to fight. I think their "glasses" are actually Virtual Boys.
