Devastator

The game's story is based on a mini-anime series, with extracts from the anime being used for cutscenes between the levels. The story centers on a man named Ryo, who begins working for a company called Yaesu as a replacement for his friend Masato.

During a test ride with a new machine, however, he is somehow thrown into another dimension. After being rescued there by a group of mecha pilots from vile creatures named Devastators, he learns that nefarious people are working on a connection between that and his own dimension, and sets out to stop them.
