M3 SMG

The M3 SMG is the fifth gun in Bubble Blast. It is also the first fully automatic submachine gun (SMG). The M3 has fast firerate, decent ammo and recoil. Although each bubble deals low damage, the M3's high firerate makes up for it.

Trivia

 * This is the fifth gun and the first automatic gun in Bubble Blast.
 * This gun is "advertised" on a billboard in the map Megalopolis that shows all of the M3's capabilities and drawbacks, however the price was tagged wrong at 2500 Credits, while in reality the gun costs 7500.
