GEO Defense – Hard Level 9: Eternity
This is my strategy for the hard level 9 Eternity for the iPhone game GEO Defense.
- Start off with two laser towers at lvl 1 connected to a single vortex tower at lvl 1
- Add 4 more laser towers at lvl 1 and another vortex tower at lvl 1
- Start upgrading your laser towers one at a time until they are all at lvl 5
- Begin adding missile towers along the straight stretch
- Don’t start upgrading your missile towers until your laser towers are at max lvl 7
- At some point I had to add the laser tower at the end and connected it to a vortex tower because the purple stars can sneak through

You’re a lifesaver, man. That level was driving me nuts.
I put two shock towers above and below the right vortex. got them up to level 5 with the missles. my back up laser tower and vortex got up to level 5 too. only two laser towers at the bottom. same ammount of missles. result: none of them got through.
I used your strategy, Josh. And it worked Like a charm.
