This is my strategy for the easy level 1, Beginner Swarm, for the iPhone game GEODefense Swarm.

High Score (114, 855):

1. sell all three starting towers
2. place the two towers at the end and upgrade the one closest to the end to level 2
3. immediatly after the first wave, upgrade the same tower to level 3 and place 5 more towers
4. place 6 more towers as fast as you can, once the 6th one is in place you can continue to upgrade the tower closest to the exit and the tower directly above it
5. it might take some perfect timing, but you can see in some of the pictures when I did the upgrades

No Lives Lost:

1. Place as many blaster towers as you can
