Sentinel 4: Dark Star

I absolutely love and am addicted to tower defense games, but only a handful of them reach the level of entertainment and strategy that Sentinel does. This is the best one yet imo because anything and almost everything is upgradeable, so many different tweaks and improvements gives it great replay value. I couldn't recommend it enough especially if your a TD junkie!

Look forward to playing Sentinel 4 as I have spent many hours on one map just to annihilate everything because why not... its my stress ball. Talk o you again as soon as I have played!

What I like about this game is the new environment and new turrets(Different turrets that you ever see in the TD games) and also new weird alien enemies. I already played a lot of TD games but this one is very different than the others..you have a sentinel that can level up and use the stats you got to make your sentinel strong, Your sentinel has a skill, Amazing turrets and more. Good Job Origin8 this game is highly recommended to all TD fans. Just waiting for the next installment of this game KEEP IT UP!

Loved everything about it. It took some time to adapt from the third instalment but after that I have had nothing but fun. I have completed all difficulties and the only thing left for me to do is upgrade the rest of hee is. I have at least 100 hours in this game over the course of almost 3 years.

Much worse than Sentinel 3. As another person mentioned this has lost the simplicity S3 had, also the enemies are lacking creativity & lack the effort the units had in S3 regarding abilities+HP. Same goes for the turrets. Also doesn't display properly on S7 edge, seems to be stretched. Fine for tablets -even pruchased HD Ed. Please go back to the drawing board and make another interation of S3.

You simply can't find a better tower defense. Everything about it is pure excellence. The previous installments were top notch also, but the first and second version are unfortunately no longer available to purchase. Looking forward to what comes next from origin8.

Doesnt work on galaxy s8. Icons missing and game all over place. Devs ignored my last report. This post is so ppl dont waste their money.

The graphics and sound are excellent, the enemies scary! Only 5 stars on a tablet, some control's can be hard to see against a busy background. LG G Pad 4.4.2

As addictive as the best of TD games. The in-game purchases ruin the experience a little bit, but are not essential when the grind is so fun.

But already finished it, so when is sentinel 6 coming? [Edit] earth to devs!!! Earth to devs!! Played it several times now, need sentinal 5, stat! :)

This new update messed up the game, at least in my xperia z1. Part of the screen is cut out, and because of this i cannot longer see the start game button. Please fix this. Like this i cannot longer play. (Update) Thanks for patching the issue.

The graphics and sound are excellent but not groundbreaking like Sentinel 3 was at the time. The dev has made some improvement in the buttons layout but they can still be hard to see against a busy background. LG G Pad 4.4.2

I love this game!! But I don't like the fact that the selection for our option on the screen has to be there. Can u update this game so we can see full screen of action like Sentinel 3 where you tap it and it just happens to have full screen action pack strategy game instead of having buttons there all the time to cover the coins you have to get and not see them? I'll rate 5 starts if you do!!

New version whatever has happened awful on s4 i9505. Takes 30 secs to resume from app change. Buttons on screen dissapear randomly and phone heats a lot. None used to happen when i last played bout 6 months ago

Gave it four stars initially but down to two due to constant freezing problems.Also don't like the control layout, to complicated and cluttered. Unfortunately this game is not nearly as good as the third sequel.Shame on you Origin, you could have done a lot better.In app purchase in a paid game is also something I utterly dispiese.

Fun game, far bit to it with its progression system. The only gripe I have is the UI gets in the way sometimes.

I enjoyed s3 so much, I played through the full campaign several times. S4 doesn't disappoint. It brings a lot of new and fun gameplay mechanics, so it feels fresh, yet the addictive fun of the original still shines through. Great job devs.

Great sequel BUT. Works fine on my cheap Chinese phone yet crashes randomly and very often on my Tablet and Andy for Windows. The Andy problem is a real shame as it is so good on a large screen. Any Ideas Origin?

If you ever liked any TD games then dont hesitate to buy this game! Its far beyond any other game.

Even after paying for download, there are still in app purchases. Scam!

how the hell do you make a td game over 300mb in size.....hope its good just waiting for dload finish....3months so for still downloading lol

Was getting error 489 on my tablet at install but it was Google's fault, thanks for the help. The graphics and sound are excellent but not groundbreaking like Sentinel 3 was at the time.

Love the game but one small problem that requires attention at max speed on endless mode the game freezes it has happened again on psycho difficulty at twice the usual speed if that can be sorted on next update please. Im updating the issue again with the game crashing at certain points during play, even boss fights when defenses go crazy and en-mass no matter the speed of play to a point thats annoying ill rate 5 stars again if this can be sorted

like the game, but did not download the additional data s explained in the instructions when I run it for first time, so I hope it will keep on working.

I used to like this game a lot. Purchased Sentinel 3 and then now 4. While playing Sentinel 4 I purchased some Star packs a few times. One day the app crashed and all my in app purchases and my game progress is gone. I contacted support but no one came back even after 1 week. I used to like this company when things are good. But now I'm not so sure because they didn't back me up when things went wrong. I'm going to try and see if I can get all my purchases refunded with Google's help. Stay away from them.

Great follow up to sentinal 3. However UI is way too busy with too many buttons in both layout modes. Really need to simplify it and remove some of the buttons. Half those buttons don't even need to be there. Also really wished there were bigger maps. Since some of the more powerful towers take up more space. This makes tower placement limited. However I love how everything can be upgraded. No map reset button. Overall I prefer the previous version but I would still recommend giving this game a try.

Is there no option to change the skill/attribute points like in sentinel 3? I'd love to see that option return.

Great game, fun and easily one of the best TD games out. Please make it available for Android TV and the nexus player. Would love to see it on the big screen without having to cast.

I love this game but hammers your battery on fast forward through the levels and also gave me wrist strain from playing it to much lol. More levels please. Aslo where did the slow down turret go for flying enimies?.

Just to let you know, there is a bug where if the game is paused and you turn the screen off the game freezes and cannot be resumed. A year on and this still isnt fixed. Lost 35 star chips and cant get them back.

Waiting for 5, great job.

I have played nearly every tower defense game on the market and this game is hands down the best game in its genre. I've played this game for hours on end.

Great game but I wish there were a quicker way to start each level than clicking and waiting for each dialog at the start of the level. Some dialogs you have to sit and wait for it to be dismissible.

More!! Make more games! Take my money. Fun game and worth the price

One of the best in TD genere
