The game engine for Alien Breed II was largely rewritten to allow smoother scrolling between screens (the code for which was carried over to another Team17 project, Superfrog, a 2D platform game). The graphics were also vastly improved, as were the size and number of levels (there are 17 in AB-II compared to 6 in Alien Breed and 12 in Alien Breed Special Edition 92). The difficulty curve for AB-II is also steeper than that of its predecessor.
Alien Breed II is the only game in the series that gives players the option of choosing between four characters, each with their own specific strengths and weaknesses.
Alien Breed 2 received positive reviews from critics upon release. Amiga Computing Magazine praising the game as a "classic" due to its enhancements upon the original game.[2]Amiga Action similarly described the game as "addictive" and a "quantum leap from its predecessors", although noting the game was highly difficult.[1]
