There's a MANUAL kickback which you fire w/the other button on the left. Use it wisely :)
Relight the kickback & increase bonus multiplier by completing the four top lanes.
Hitting pod targets on the upper right lites a random # of swarmers. Hit swarmer bullseye or standup to kill each one. Destroying all = 50K.
Extra button on right = smart bomb. You get 3 at the start of the game. Smart bomb destroys all landers, baiters & swarmers on playfield.
