Blue Shark

Star of the Show

According to Taito developer Tomohiro Nishikado Taito did not have faith in Space Invaders before its release, as it did not guarantee a minimum playtime per credit as other games of the time did. Blue Shark (distributed by Taito in Japan), with a guaranteed 99 seconds of playtime, was chosen to be their focus at a 1978 arcade expo, with Space Invaders in a supporting role.
