Big Wars - 1993 - Directed by Issei Kume and Toshifumi Takizawa
90 minutes, animated
Based on the novel by Yoshio Aramaki
In the future, humans set out to colonize Mars. Only problem is, somebody has beaten them to it. On the red planet, humans encounter aliens known as "The Gods". With their stealth battleship "Hell" and their nymphomania-inducing mind control rays, there's only one thing that can stop them- the land battleship Aoba!
A squarely mediocre anime, worth a rental if you've got nothing better to watch. |
