Ghost Line Defense

Skeleton hordes and ghost trains are rolling down the tracks! Flip the switch to send every train onto the Fire, Barrier or Pit branch, build eight kinds of defenders along the rails and upgrade your traps. Call down rain, lightning, ravens or a Fire Dragon, and beat a different boss train at the end of every level. Defenders carry over between levels and progress is saved after every wave. Clear 12 levels, climb 15 ranks, then survive as long as you can in Endless Mode.
