AC JetterEdit

AC Jetter

AC Jetter

Middleweight, two-leg AC design with respectable firepower and good close-in rushing performance. Overall mobility is somewhat lacking.


This guy is fairly tough opponent, but not as hard compared to a foe like No. 2448. He fights quite aggressively but his movements are rather predictable. He usually goes airborne when using his machine gun and multi-missiles and glides on the ground when using his grenade launcher. He does have a blade but is hardly ever seen using it so that isn't a concern.

His most powerful weapon is, as you can tell, his back-mounted grenade launcher. He usually glides towards you on ground, to close distance with you to guarantee a hit with his grenade launcher which can deal a lot of damage to you if you don't have good defense. His missiles aren't too threatening as multi-missiles in Last Raven aren't highly accurate and can be easily avoided. His machine gun has good fire rate but is not very effective as an individual weapon. Thus, the key to defeat him is to simply avoid his grenade shots and have sufficient firepower to defeat him, as his AC does have surprisingly high defense and AP for a middleweight bipedal.
