This is my strategry for the medium level 5, Inward Spiral, for the iPhone game GEODefense Swarm.
No Lives Lost:
- Start with the laser tower at the top
- Add 6 blaster towers going from the laser tower down to the bottom (3 on each side)
- Continue adding blaster towers toward the bottom always keeping one more blaster tower on the right side than on the left side
- Once you’ve built the central path leading to the exit, start building the line of blaster towers from the lower left, around the top and to the lower right
- Now you can add blaster towers in the gaps and laser towers at the end of the straight paths
- Upgrade what you can
