This mobile game was announced at the GRASSHOPPER 1st COLLECTION private event on September 14, 2011. This was one of the only times it was discussed publicly, however, and it is now believed to be cancelled. Alternatively, it may have folded into another mobile game it was announced alongside, エイリアンバスターズ, as images from both games seemingly depict the completed game DARK MENACE. The game was announced as 人間 vs ゾンビ, however, by its next appearance the title had been reversed. Its final name when translated into English was Zombie vs Human.
