This mobile game was announced at the GRASSHOPPER 1st COLLECTION private event on September 14, 2011. This was seemingly the only time it was discussed publicly, however, but it is believed to have been the working title for DARK MENACE as its name translated in English to Alien Busters, much like the playable Abyss Hunters in DARK MENACE.
