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...

Customer Reviews

Challenging, but fun and addictive!

One thing that does knock this game down a few notches is that the tower costs for the same towers, and the health/speed of the same enemy types vary across levels, and increase at different rates. E.g. the price of a blaster isn't always $10, and the amount of damage a Star creep takes from it isn't always the same. While this does keep levels unique, it makes losses feel cheap while you're still adapting to the level's parameters, and you can't necessarily be confident that a strategy you used earlier with the same creep types and same weapons will be applicable to other levels. It might've been better to have lengthed/shortened the courses more, given more/less starting money, or even have more enemy types, to alleviate this.

The wave difficulty seems to not always be balanced at times either. E.g. on Medium 3, you can feel like you're keeping up only to have the last wave sucker punch you and make you lose after a 20 minute build-up.

In spite of these gripes, I enjoyed the game because even though some levels could be almost phone-throwing frustrating, I felt like I knew I could improve if I walked away and came back. This real challenge made the game really rewarding.

Finished all 38 levels on v1.7. iPhone 7.

Even on an iPhone 7+

The graphics are pretty good, and the gameplay is VERY hard (which to me makes it great) and well thought out. Even though this game will probably never be updated, still worth the buy in 2017

Fantastic TD! Thanks for the Update!!

If I recall correctly, it's been several years since the last update, and I'm extremely pleased to see that this app hasn't been completely forgotten about. I used to play this game for hours at a time back on my iPhone 3GS; however, the developer didn't keep up with updates so the game became buggy and irrelevant on new phones... Until now. This game is one that I've always refused to delete off my phone in hopes that there would be an update. Thank you so much!

I would love to see an update to GeoDefense Swarm too.
