How do I survive swarm 18: the centipede in a field of orbs?
Concentrate more on getting rid of orbs and dodging the centipede than actually doing significant damage. When the centipede gets close, turn away from it and let it roar past. After a few passes, most of the orbs will be gone and the centipede can easily be finished off, just like swarm 10. Warning: If you stay in the same place while the centipede is turning, it could double back on top of itself, catching you by surprise. If you move away during the turn, this won’t happen.
