ACA NeoGeo: Mutation Nation

A larger character choice would be good, but there's a solid range of enemy attackers to deal with during your playthrough. A number of moves (including the sometimes tactical use of specials) keeps the fighting entertaining whether playing alone or with a friend. There are some decent character designs for the mutants and robots, with some nice touches in their animations such as a transformation or the way a seemingly human foe's face is punched off to reveal the robot inside. Once cleared there's not a lot of immediate replay value, but you can always try and improve in the Hi Score and Caravan modes; whenever you do boot it up, Mutation Nation provides a great scrolling beat 'em up fix.
