As soon as I open the app it takes me to a screen that says page cannot be found. Even if I close the app from the list of apps running when I restart it the app will be in the same place. The second one is pretty cool but a little boring if you play survival mode. The mission mode is very hard which makes too large of a contrast.

Let me start off by saying I started on the sequel. While not as great as the sequel, it is still just as much fun. I do miss the extra upgrading but it is the first game in the trilogy after all. If you have an extra dollar lying around, get Sentinel 2, but if you have $2, get this and the sequel. Both are worth every penny!

This game is pretty good but, it does get old quickly. The drones you can deploy are cool but it takes them forever to do anything. If you want a tower defense game with a lot of everything 3 different game modes 3 different difficulties and 9 different maps get Fieldrunners.

I've played many tower defense games so far. This is one of the stupidest games ever. Not strategic at all... Graphic is also ugly. I am warning you. Do not buy.

This is what I have been searching for: a tower defense that actually involves defense, not some "let's go travel somewhere, take people's stuff and then shoot them when they protest" game. I only wish that they had an iPad native version.

The core gameplay of this game is decent. Nothing special, and doesn't really require much strategy once you figure out what to do. The critical flaw of this game is that it is so short. There are only four levels, and since the gameplay isn't deep enough to allow the player to come up with imaginative solutions, there's really no point to replaying a level, as you'll essentially be implementing the same setup each time. I did everything there was to do in this game in about 3-4 hours. Not exactly a good investment, considering other TD games like The Creeps and Plants vs Zombies offer enough stages and gameplay options to keep the player interested for hundreds of hours. I almost thought that I had gotten a demo of a full game, then I realized this was the full game. How disappointing.

I get an error while the app tries to load an external page before I can even play a game. Wasted yet another dollar...

Is this game free? It says install. Then I click on it then it says $0.99.. Then a couple seconds later it says install again
