"Robo Army" is your average beat'em up. A genre that's a dime a dozen on the Neo Geo. This one would even register as fairly mediocre. There's some depth thrown in with various special attacks, but mechanically nothing veteran arcade fans haven't seen before. So why do I like it so much then? Well, this has some of the coolest sound design of any brawler on the platform. The clanks of metal robots knocking against each other is really fun and complemented well by appropriately janky looking character models. This games got an old school esthetic and it rocks it well.
