Sky Blue (originally titled Wonderful Days) is a South Korean animated film that uses a blend of 2D and 3D animation.
The following firearms are used in the animated film Sky Blue:
Several ECOBAN officials are seen using SIG-Sauer P228 pistols with black frames, silver slides, and gold-plated barrels.
Shua carries a STI Edge at the beginning of the film.
Beretta 8000 Cougar
During a single shot during the final scene, Cade's P229 turns into a Beretta 8000 Cougar with the same color scheme and the ejection port enlarged to the size of the P229's.
One rebel fires at Jay with a fictitious RPG.
ECOBAN soldiers are armed with this fictitious (but rather conventional) bullpup assault rifle. The weapon's basic aesthetics draw heavily from the FN P90 submachine gun.
M60E3 Machine Gun
One of the rebels is seen using a vehicle-mounted M60E3 machine gun during the finale.
Several members of the Merrian resistance use this fictional rifle. The weapon draws heavily from the aesthetics of the Sten submachine gun and sports a very crude, stamped-steel feel.
A few sniper rifles appear briefly in the film. Both are fictional designs, and are not seen clearly enough to examine any real-world design influences.
Miscellaneous Fictional Weapons
Various extras are seen armed with an assortment of fictional weapons.
One of the rebels uses a generic "can shape" hand grenade.
