Intriguing gameplay twists in which you can waggle the ship from side to side to fire out side projectile lasers and build up the multiplier to the maximum twelve, hence the title. The levels are intelligent in the sense that an extra squadron will be dispatched to bring down the grizzled shmup vet down a peg or two if you've been cruising through the level. Smart bombs also have a vortex effect after use which acts like a shield from which you are safe as you fire indiscriminately out. The sprites look sumptuous if you have time to take a glance.
