The only review that was decent enough, was from the German PlayStation Magazine called PlayStation Zone (later PlayZone), which the mag scored a 77% and also included a playable demo of the game on its cover disc of the fourth issue, in where the game was reviewed.
In one particular review from a German games magazine called MAN!AC, the review, which scored the game 2 stars, described the "brave pilots" on the cover above as "clowns".
