  Julia Stryker: Played this on my fiancee's iPad Mini the another day. Fell in love within a few mins of video test. Endless mode is where it's at. Literally can't receive bored of it.

  Jim Kopp: This mini game was previously rated at 5 stars. Had to factory restart my Nexus 7 (thank you Google for thoroughly testing the Lollipop modernize before pushing it out), but now the mini game won't even download. Its a good mini game if you can actually install and play it...

  Tim Pulver: Like a drug. Hours will go by like nothing. When you finally stop, it will be 3am and you have to go to work in the morning. I had to uninstall as it was taking over my life. It's a love/hate relationship with this mini game. Very entertaining and well place together, and creative.

  Marquis Moore: Simply one of the best turret defense mini games around, well worth every penny. Modernize: Latest patch fixed the Nexus 9 scaling problems.

  Matt Decker: I have been a Sentinel loyalist for years and was thrilled they released this fresh ver on Android device (Playing on G Tab4). This fresh ver allows for complete customizing and upgrading of turrets/structures, as you progress. The designers have clearly place a lot of thought into the newest installment and it is greatly appreciated. Would rate 6 stars if I should!

  The Sedrick Channel: Even better since the modernize. I'm fresh to the Sentinel mini games and I must say this is turret defense perfected. The mini game is quick paced, attractive, has plenty of options for defense and permanent upgrades, an good soundtrack to match the action, and fluid video test. Worth every penny.

  Steven Oz: Fun mini game, far bit to it with its progression system. The only gripe I have is the UI gets in the method sometimes.

  Adam Dri: Note 4. I'm fresh to android device from ios and this is one of very few mini games that just work perfectly. Well worth the cash.

  Saquib Kabir: Sentinel 2 was one of my favorite mini games on the iPod touch...I bought em all because they are worth it. Hours on end of tactic and fun! This mini game would be better on a larger screen than my Nexus 5 but still the graphics and mini game play are good!!! Worth Evey dollar!!!

  A Google user: If you even remotely likened Sentinel 3 (which you did) then this is a no brainer. Related enough to be familiar yet fresh and improved. Simple purchase!

  Kelvin Chin: I've been waiting for this since the latest sentinel mini game. Only played a few levels so far but it looks good and even more fun than sentinel 3! Thanks!

  Nathan Lowe: Best defence mini game for mobile ever. Outstanding graphics and hd color arrangements in the Sentinel series

  ThatGuyJerry: It's a good turret defence mini game with one downside. If you wish to replay the campaign you can't. There is no fresh mini game option.

  Thomas Sutherland: I absolutely love and am addicted to turret defense mini games, but only a handful of them reach the level of entertainment and tactic that Sentinel does. This is the best one yet imo because anything and almost everything is upgradeable, so a lot of various tweaks and improvements gives it good replay value. I couldn't suggest it enough especially if your a TD junkie!

  Craig Iannello: I enjoyed s3 so much, I played through the full campaign a few times. S4 doesn't disappoint. It brings a lot of fresh and fun video test mechanics, so it feels new, yet the addictive fun of the original still shines through. Good job devs.

  A.D. Cole: You simply can't search a better turret defense. Everything about it is pure excellence. The previous installments were top notch also, but the first and second ver are unfortunately no longer accessible to purchase. Looking forward to what comes next from origin8.

  Daniel Dickson: Good turret defense mini game, the graphics are awesome, very colorful. The video test is good, a awesome amount of dozens and customization, gives it a really awesome replay value. Defently worth every penny, the only disappointing thing (which has nothing to do with the mini game) is the fact it comes with inn apk purchases after the initial fee.

  Rob Freiboth: The cloud save feature is good!!! Another devs take note! So nice to switch from smartphone to smartphone and continue progress. Will modernize as I receive through the mini game but so far its a blast to play.

  W0ke 420: The fresh system takes some time, fresh users may feel somewhat out of depth with the sheer amount of things to make batter and do. But overall, a brilliant, masterful fresh powerhouse of the turret defence genre. Lets hope its not other 4 years until we see 5. (did someone say add-on origin8?) :3

  Jonathan Boulanger: This recent installment is a good follow-up on the Sentinel series. A fresh mix of turrets as well as a more diversified kind of upgrading system makes this mini game hard to place down. So far I haven't felt like I've had to "grind" to level up turrets, which is good. The higher difficulty levels are certainly challenging, but enjoyably so. Early on performance was awful, but updates have drastically improved things.
