This is my strategry for the easy level 8, Road not Taken, for the iPhone game GEODefense Swarm.

No Lives Lost:

1. start with a blaster tower to direct the creeps down the rightmost path, place two thumper towers in the top-right corner, place a single missile tower below the thumper towers to block the path
2. Place a missile tower in the top-left position
3. place a missile tower in the lower-left position
4. now place the two missile towers in the top corner
5. begin upgrading the missile and thump towers. I always start with the thump towers and then work my way counter-clockwise with the missile towers starting from the lower-left position
6. near the end I added three more missile towers to help things out
7. I got my thumper towers to level 7, and left all the missile towers at level 6
