Origin8's new tower defense game Sentinel [App Store] is one we've been keeping an eye on since its release last week.

Despite the flood of Tower Defense games into the App Store, it seems developers can continue to bring something different to the App Store with each incarnation. Sentinel is a well polished Tower Defense with nice graphics and animations that help complement the gameplay. The video shows off the game's style:


The game changes up gameplay a bit by requiring you to defend the walls/barriers from destruction rather than preventing a set number of creeps from crossing the map. Like many of the other Tower Defense games in the App Store, you are provided with set paths along which the creeps traverse. The game comes with 3 maps and 4 difficulty levels. Other features listed include:

  • Tactical and unique gameplay which takes tower defense to the next level.
  • Use the landscape and destroyable defenses to maximize the effectiveness of your weapons.
  • Beautifully rendered environments, towers and enemies.
  • Endurance mode to challenge the most hardened of players.
  • Compete with players worldwide with the online high score system. View and compare scores seamlessly with the in-game score browser.

The game has been well received by our forum members and the developer has been an active participant. Origin8 reveals that a Lite version is currently pending and they are also working on an update to the full version.

    Nice style. TD has room for a lot of variety, I am realizing. I wouldn't have expected to need more than 1 TD game, but I have 4 now, all different, and this one of several others I'll probably get too.

    im not sold on this game...until they update the load time between waves it is VERY slow paced....the first 10-15 waves dont really require you to do much...so its a LOT of watching, waiting....
    needs more...doesnt really out-do some other tds...like geodefense, which is only .99$ and way more fun...

    Fun and better than average graphics but not much enemy diversity and exceedingly difficult against flying enemies as they can't be slowed. This is the last tower D game I buy for sometime as I have 7 Cities, GeoDefense, Fieldrunners, Crystal Defense and the Creeps.

    I'd say the most boring of the ones I've played is the Creeps. GeoDefense is exceptionally difficult even on easy, Field runners is just alright, Crystal Defense is a shoddily done port but has probably the best strategy but overly difficult and 7 Cities was fun but just didn't have enough towers.

    Very solid and eye pleasing game.
    I do like the idea behind defending the barriers.
    The whole game has a great feel to it, hard to put down.

    I do wish the developers add more alien enemies to the game, hopefully in an upcoming update. Four different enemies is not enough for TD.

    What I like about this game is that it brings new things to the table:
    - Barriers to defend
    - mutants literally going apesh*t to break them down!
    - drones to repair the barriers
    - drones also mine resources to boost cash reserves

    Also I thought that the gameplay video alluded that the music would be in the gameplay, which just captured my heart as it gave a sense of something epic. It was in fact limited to the opening screens due to resource issues, but they may try to add it in as an option.

    Overall it's a very solid game, doesn't crash unlike Fieldrunners has since the latest update, and makes a valid claim for it's stake in the crowded TD market.

    I find the game very good. Not sure if it's the best TD so far - it's this or Fieldrunners in my opinion.

    It's not perfect (but what is?) but it's definitly worth the money. I like it :)

    The thing i like about fieldrunners over others is the free reign that the bad guys have, having to redirect them is half the fun to me.

    What's everyone's strategy? Build and strengthen each weapon, or wait until you have the money and buy full blown massive destructive ones...

    I'm doing the build and strengthen strategy, furthest I got was Wave 110 in Endurance mode.

    Ok, for real, I loved this game. It was a great game until I started dying on the 95th wave on the third board. What the hell!?!?! What is the strategy? I've tried distributing my lazers all over, upgrading lazers, building repair bots asap.. What am I doing wrong? How the hell do I kill the flies?

    This game rocks btw, but I'm completely stuck. I hate being this stuck.

    I absolutely love this game when I played it on a cousin's Ipod and I couldn't put it down. My best strategy is to use alot of the cheap turrets ($20), some bombs ($50) along with a couple of Slow Towers ($100) to help slow the small and fast buggers enough for me to kill em, upgrade them all, then go for the red Ion Cannons ($150), blue Sniper Towers ($250), then put in a couple of Beam Guns ($300) for main def. and boss killing (every 30 waves). That combo really helped out alot, I got to wave 150 before the bosses (5 of them!) broke through the final gate. Final score? Over 3.6 million points.

    Oh, I forgot to mention, I really hope that Origin8 puts this game out for PC and Mac users, I'm willing to bet it would be so much better with computer graphics and speed and we would go ape§h!t for more levels, enemies, bosses (although the ones they have now are pretty tough if there are more than 3), and maybe a Super Endurance mode where bosses come in at every 15 waves?
