Great tower defense game - I played both the iPhone versions of Sentinel and they were great fun. Now that its an app for my MB, its even better. Plus the updates to the maps, addition of the commander element and a levelup style of weapons and commander abilities makes it worth the purchase.

Original and one of the best - In my opinion there are only 2 tower defense games that are absolutely essential on the Mac App Store, IBomber Defense & Sentinel 3. IBomber is the standard for tower defense games, with it's WWII setting, and most TD games are basically a clone of this type of game except for rare exceptions like Sentinel 3. Sentinel 3 holds it's own with it's upgradable towers, unlockable weapons, and killer enemy waves; not to mention it's amazing graphics, sound, and UI. The additions of a Commander (which makes you feel like much more a part of the action) and multiple gates to defend (which adds multiple levels of strategy to the game, with the new need of a possible fallback position) are what makes this game truely special. Though the Commader is provided to you from the start there are a TON of upgrades you can earn for him including weapons, new abilities, and his individual stats (health, weapons range, strength, firepower). The campagn consists of 20 levels with 4 modes of difficulty, so you'll need those upgrades, and has a ton of replay value; not to mention the Classic mode (which is kind of like a challenge mode with set weapons and powers for different maps) and of course, Endless mode for all 16 maps. For 3 bucks this game is a steal, for the high quality of it's gameplay/design and quantity of content it's also one of the best games I've bought on the Mac App Store.

Great game, still has some bugs... - During campaign mode, it will randomly start the first level rather than the level I have selected. Also need to spend a little more time optimizing the UI for the Mac, rather than Cocoa-Touch. Fun tower defense, would have five stars if they fix the bugs, and do a little more work on the UI.

Excellent TD - I have sentinel 2 on my iphone and love it. I was browsing the Mac AppStore, and figured this was worth a try. Very glad I made the purchase. This game is very good. Excellent graphics. Very good gameplay (although it is sometimes a bit of a pain to click on your towers). I like the new commander mode which allows you to outfit a mech for use on the various levels. All in all, this is a significant improvement on an already polished iOS game. It made the translatio to Mac very well. If you're a TD fan, this is one of the best in the AppStore.

Good tower defense game - Good for the price. Interesting weapon and upgrade choices. There does seem to be a bug, as someone else mentioned - after finishing the campaign on "easy" I was unable to play anything other than the first level on medium.
