5.0 out of 5 stars Maybe the Best Tower Defense Game Out There... November 16, 2011
Verified Purchase
I'm not normally a huge tower defense game fan...but with that said, I do have quite a few of them, because they are a great game type to play on the go on a phone or an iPod.

I have played Sentinel 3 several times, and I have to say it's probably the first one of these types of games that has drawn me in instantly and just kind of hooked me.

A note on the graphics...downloading and installing the HD graphics pack will take up quite a bit of memory, about 40 MB, but it's definitely worth it.

On the Kindle Fire, the graphics SCREAM!!! They look simply amazing.

It's a great game, that has exceptional graphics. If you have the device that can run it in HD, do yourself a favor and run it that way...it's spectacular!!!

5.0 out of 5 stars I like this game - and I don't normally play games October 15, 2011
Verified Purchase
I bought this and have tried it on my Sammy GS2 ... and Acer Tablet. Works great on both - of course easier on my aging eyes on the Tablet.

I can't say what the non-HD graphics look like - since I downloaded the HD add-on pack right away - and pretty impressive -- to the point of almost overwhelming. Before this -- Field Runner is my experience with Tower Defense games --- and I really like that game too. Sentinel 3.. I am going to guess is a bigger hit for those that play games more than me ... my goal is to clear my mind and relax - and S3 may be a little too challenging for that!

2.0 out of 5 stars Problem with in game purchases...beware! March 29, 2013
Verified Purchase
I really enjoy this game, it is both addicting and fun. I have played through almost the entire campaign and have few complaints. The levels are often repeated and do become a little repetitive, that really is the only con I've experienced. That is until I had to start over due to device issues. The game has a built in store that offers to unlock all armor, towers, and levels for a small fee for each one. Not wanting to start all over, I purchased all but the levels. Everything unlocked fine and I enjoyed all the unlocks I had worked so hard for previously.

Upon exiting and starting the game again the game informed me that all my unlocks had been refunded. However the options to buy them are checked and state that they are purchased. I have no upgrades upon starting the campaign. This is very frustrating as I haven't seen any notice on my credit card of a refund. This stinks and I would recommend avoiding any in game purchases... maybe even the game itself. Beware!

This is an awesome game but the reason I don't give it a five star rating is because it doesn't update like the one on android market. Hope amazon fix this.

4.0 out of 5 stars Very Enjoyable December 18, 2011
Verified Purchase
Positives
Having a campaign character that improves the more you play is pulled off extremely well in this game. I also liked being able add towers while the game was paused.

downside
needs work on time mechinism. I play solely on fast forward and that's not fast enough. on ff for the entire level and the final level still takes an hour and twenty minutes.

Overall
easily worth $2 buy it

1.0 out of 5 stars If I could give it zero stars I would! December 16, 2011
Verified Purchase
This was an impulse buy because I saw the high ratings, low price and the claim of HD graphics. It is a total failure on a Kindle Fire. The App installs easily and asks you to open it. It then advises you that you have to download one of two possible data package selections. The first is 19 MB for normal graphics and the second is 40 MB for HD graphics.

Now comes the rub. I experienced 10 consecutive failures to download the data packages. I tried the HD one 7 times and then it fails at various levels of installation from 20 to 75%. Once it even told me that the server had the incorrect file size on it and failed. I then tried the 19MG download and it failed 3 times at installation levels of 10 to 90 %.

I give up. Do not buy this program until they fix it if you have a Kindle Fire. Even though it is rated highly, I wish I had read the negative reviews before for I purchased it. I wasted 90 minutes trying to install it and gave up!
