The English version of this game has been renamed to Metal Buster. This game offers more than 200 robots batched with handful of unique active skills. This version also offers a wide variety of game modes such as mission mode, story, endless mode, PvP, real-time war battles, 1v1, AI battles, PvE, etc. Wow, that's a lot of modes! I actually downloaded this game since I like mechas and stuff. I made a short gameplay video of the game for those interested, check it out. However, I couldn't get into this title much. Something felt a little bit off, perhaps you might enjoy it more.
