After evacuating Earth, a ship looking for another home crash landed on a distant planet. The damaged computer tried to terraform the world to make it a home planet away from home, but ended up creating monsters like an insect-railgun.
Guardians help you fight these monsters, if you give them alcohol. While they may be tipsy (see concept art), the Guardians can deal damage. See the explosions and sparks in these screenshots?
Earth Seeker is slated for release this winter in Japan.
