The Highly Acclaimed Defense Game

*** PC World's 10 iPhone Games You CANT Live Without! *** #8: GeoDefense!!!

"The tower defence genre is a popular one for the iPhone and iPod touch, and geoDefense blows them all right out of the water." -- PC World

"If you fancy yourself a tower defense guru, and you don't own geoDefense yet, shame on you. geoDefense is a well presented, well designed game that ranks up there with the best TD titles on the platform. Score: 8.2 Impressive."

"geoDefense's vector-style graphics, pixel bursts, and warp effects more than set it apart from the crowd. geoDefense is easily recommendable for tower defense enthusiasts."

"It's bright, it's colorful, and you might have seizures while playing it but it's fun as hell!"

"If you're a fan of the tower defense genre or strategy games in general, this one is well worth your time, especially for the super-cheap price tag! Score: 8 out of 10 -- Download it!"

"Until geoDefense, I thought tower defense games were boring. Not this one. I love this game, and I went into it expecting to hate it. That means it's good. Score: 4.5 out of 5."


Something exciting and new in the Defense genre! The geometric vector creeps are fast and intense. With 30 different maps, each its own puzzle, you'll have to work fast to keep up.

Using exciting vectorized graphics, this highly kinetic game brings a whole new dimension to the defense genre. Devastate creeps with blasters, lasers and missiles and watch their energy debris swirl through the gravity wells of your vortex towers. Now it's time to figure out how to put that absorbed energy to good use...

The App Store's best tower defense game

I've played many of the App Store's offerings in the tower defense genre, and this unassuming little offering is surely the king of them all.

The key is the "every level is a puzzle" approach. In most TD games, you gradually learn to use the available towers effectively, and the principles you extract apply to most of the maps. For example, you'll usually find that some towers aren't really worth their cost, or that some towers are best deployed sparsely but fully upgraded.

In geoDefense, the maps have been carefully designed so that you can't apply the same general rules to every situation. You're forced to take a different approach on each map, so every map is a fresh challenge. Every nuance of the various towers' behaviors eventually comes into play.

I particularly appreciate geoDefense's difficulty. The maps are a genuine challenge, but they're solvable. This isn't just another insipid iPhone pastime where it doesn't really matter what you do.

My only gripe is that 7 levels of upgrade seems a bit excessive. You can't alway perceive a difference in performance between two adjacent levels. The game does use the length of the upgrade tree to force you to think strategically, but on the other hand, this does sometimes produce a bit of a "clickfest" feeling.

Fun tower defense game!

There are tons of tower defense games so it's important to create one that stands out. This tower defense game definitely stands out! The game visuals are very simple, but is very appealing. The sounds are cool, and I really like the colorful and dramatic explosions.

Everyone says to apply the same strategy for every map. While you can do this to clear very level with ease, to me, the point is to get the highest point possible. As the creeps get closer to the end, their score multiplier increases when you kill them. It's very easy to just build a ton in the front, upgrade, and pulverize everything, but try to design the defense so that the creeps die at the very last moment before you loose a life. This is what makes the game a challenge. You have to hold off on upgrades (even if you have the cash) and time them just right. Build the minimum amount of cannons possible to kill everything just as they reach the end. Try this and you may find the replay value much higher. I can spend days on just one level just to get a higher score.

The only complaint I have is controlling the direction of cannon fire. The AI can be stupid and aim for the new enemies instead of killing the ones right near the end. It's really frustrating trying to hold the position of the laser tower. Please change this!!

Great game, maybe could be better?

I'm fairly new to this, still doing the easy levels (which, as many others have noted, are in very difficult compared to most games' easy modes). A few thoughts so far:

1) I wish it were easier to position the towers accurately.
(a) In either positioning mode, one's finger often gets in the way, especially if one needs to line up with a vertical pathway directly underneath one's finger.
(b) often the positioning locks up temporarily (fraction of a second to several seconds) if you are near a location that is not permitted--i.e., instead of changing color from green to red, it jsut freezes where it was--makes it much more difficult and slower to lock-in on perfect locations.
(c) sometimes when one releases one's finger to place the turret, it shifs as a result by a mm or two to a bad position. It'd be great if there were a time-limited undo button or something for such occasions.
2) Turret AI seems a bit dumb--not sure how the algorithm works, but it definitely does not target those baddies most likely to escape. Frustrating to watch lots of bad guys escape as a turret focusses on new ones entering the map instead.

Still, this is a GREAT game, even though sometimes it's frustrating for the above reasons. Thanks for making it, and for making it so reasonably priced.
