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

This is my strategy for hard level 5 Knit Knack Shack for the iPhone game GEO Defense

• Start with three laser towers and a shock tower
• upgrade the lasers as much as you can until the creeps start coming
• once you’ve hit level 4 on your lasers you can start adding missile turrets around the shock tower
• When you’ve placed as many missile towers as you can, start upgrading them and remember to keep upgrading your laser towers as well
• I chose to setup at the end of the track so I could get a higher score

This is my strategy for hard level 4 Fall In Line for the iPhone game GEO Defense.

• Don’t upgrade any of your towers until later
• Start with a shock tower and two missile towers on the bottom
• add three missile towers on the top
• add four more missile towers
• Now you can start upgrading your missile towers as needed

Here is my strategy for the hard level 3 for the iPhone game GEO Defense.

• Start with the laser and vortex tower
• Begin by adding a single shock tower
• start adding missile towers around the bottom and right sides
• keep upgrading your vortex and laser towers when you get a chance
• When you run out of room start upgrading the missile towers

I might have gone overboard with all the missile towers and shock towers in the top-left section, but sure as heck nothing got through!

Here is my strategy for Hard Level 2: Angular view for the iPhone game GEO Defense

• I started with the three laser towers and the vortex tower, upgrading them all to level 3
• Then I added the three shock towers
• With those in place I began placing missile towers along the top first, then the left side, then the right side
• With all the missile towers in place I started upgrading everything
• Get the lasers to lvl 7, remember to continue upgrading the shock and vortex towers as well
• I finished with most of my missile towers achieving lvl 4

This is my strategy for the Hard Level 1: The Eye for the iPhone game GEO Defense.

• Place 3 blaster towers at the entrance of the path, right where the straight stretch makes it’s first turn, and upgrade them all to level 2
• Continue placing blaster towers around the circle and upgrading them to level 2 as quickly as possible
• Once you’ve filled up the inner portion begin upgrading the last two towers as much as you can to shoot the last creep

This is my strategy for the hard level X Factor for the iPhone game GEO Defense.

• Do not upgrade any towers in this level
• Start by placing 4 blaster towers in the center
• Place 2 shock towers – one in the bottom section on the left, and one in the left section on the top
• Place 8 missile towers around the center, 2 in each section
• Place the 2 remaining shock towers
• Now place missile towers as fast as you can along the final stretch of the path

This is the strategy I used for the Final Push level on the iPhone game GEO Defense.

• Don’t upgrade any towers on this level
• Start with the 4 blaster towers
• Add a couple of missile towers
• Add the 2 shock towers
• Start placing missile towers as fast as you can anywhere they will hit something

GEO Defense is a tower defense game for the iPhone. It’s easy to play, but hard to master.

Here is my strategy for the Resistance is Futile level.

• start with a couple of laser towers that will take care of the first few waves, just keep them at level one for now
• begin placing more laser towers at the top of each sharp corner, keeping them at level one
• when the creeps start to get through the lasers and into the upper track, place blaster towers in the gaps on the top track
• once you’ve placed 5 of them, place a few blaster towers by your laser towers
• now place as many missile towers as you can
• when you’ve ran out of room for missile towers it’s time to upgrade all of your lasers to max
• now upgrade the missle towers along the top edge of the screen as much as you can and the end should be in site
