For fans only Getter Robos only dedicated game so far, it plays like a primative Super Robot Wars with the main difference being in the combat, on your turn you of course attack but you don't get any percentage estimate on if you'll hit. On your turn you can dodge if you like but it gives no estimate on if you can, seems fairly random.
The game is also quite exceptionally hard and many areas require good map movement, this is countered by the fact, Friendly Units can't move through each other, which means you can wind up boxing yourself in pretty easily.
The mini-game, while only being around 20 seconds long in each burst is quite fun and until Another Centurys Episode 4s release, the closest we have to direct control Getter, even if its only the jets trying to combine.
