The party moves around the overworld and through the dungeons, fighting off wild Zoids and enemy pilots as the player attempts to complete the game.

It is revealed early on in the game that the Emperor is after the 'Time-Space Transmission' technology recently discovered by Arcadian scientists; wanting to use it to travel back in time and conquer Zi.

Most of the game is spent travelling back and forward in time to stop the Emperor's henchmen from altering history.

The game follows 'Zeru' and Juno as they attempt to foil the efforts of the Backdraft Group and the Terra Geist organization, along with restoring the timelines to their original states.

This translation is mostly inaccurate, incorrect most of the time and nonsensical at others, with numerous spelling and grammar errors.

This made a small number of boss battles significantly easier as the player would only have to survive four turn cycles and then attack the weaker individual Zoids after the Unizon broke apart.

For example Liger Zero Phoenix (before any modification) would have more powerful weapons while in land mode, but would be slower and less evasive.

This was primarily a problem with the first game; the later releases removed most of the character-specific Zoids, along with some of the extraneous variations.

Another common complaint is that Zoids that feature heavily in the anime (such as the Blade Liger, Liger Zero, and Genosaurer) that are commonly considered 'all-powerful' by Western audiences because of their use as character shields, are far weaker in the game than they are portrayed to be in the anime.

The majority of these complaints come from people in Western Zoids fandom, and have little or no familiarity with the Battle Story originally associated with the models.
