Undercover Cops Gaiden - Hakaishin Garumaa — About this game
Undercover Cops Gaiden: Hakaishin Garumaa sends one of three city sweepers after a kidnapped girl's twin sister. The rescue advances across a board rather than a street full of real-time punches. Numbered tiles decide movement and feed card battles, so the choice that gets you farther can also spend strength useful at the next encounter. Compare attack and defense opportunities, watch health and use the rewards from a victory to prepare for the road ahead. A stage password lets a completed section become a reliable point to continue from.
