The super-carriers, developed by scientists and intended for use in the transportation of space shuttles, have been taken over by the Bydo, and now threaten human existence. Unfortunately the scientists designed them too well and they are nearly indestructible.
Gigantic Attack is stage 3 of R-Type Delta. This stage is centered around the colossal super-carrier Trojan. This carrier possess fierce weaponry that will make a pilot's life very difficult, but getting behind the carrier allows a pilot to attack the core...of course, dodging the various weaponry and limbs isn't easy. It takes place in the ruins of a construction site.
