Zoids: Mokushiroku (Lit: Apocalypse) was released on the 21st of December in 1990. It is a strategy game wherein a player controls units, however, when two units engage each other in battle, the game shifts into an action-oriented format. The game is set at the end of the OJR Battle Story. One of the unique features of the game is the ability to choose whether it plays like a turn-based strategy game, or a real time strategy game. There are also earthquakes that occur during gameplay that would alter the terrain, sometimes opening up new routes or revealing previously unaccessible upgrades. This game was only released in Japan. It was later re-released in 2009, as one of the games available on the Wii's Virtual Console.
