Customer Reviews

very addictive!!

Plus -
great game. very strategic in nature.

- Initial walk through/guided tutorial is very well done

- True 3d which is awesome. and as the head of a game technology program at our college(New River Community College) that scripts with the UDK, it is super well done as far as the level design, AI and Assets. 5 Stars+ here for sure

I like the UI better in this 2nd version. A little easier to upgrade.

Playability is smooth and holds your attention throughout the levels. Definitely have to be on your "A" game to get through some of the more difficult modes.

Minus -
As a CCg game, do wish however that when combining cards that you would get a more effective card and would not continue to get same lame card that you just combined two of. This seemed to be a very weak point in the first go around. We will see how it pans out in the more advanced levels

- Also though I truly understand and appreciate the need to make a profit, unless you have very deep pockets, the purchasing of cards/crystals can be devastating on the 'ol wallet in this game and on a teacher's salary, very limiting.

I will rate this at 4 3/4 Stars. a few more tweaks and a little less emphasis on costly upgrade purchasing, and this could very well become the most EPIC. of all TOWER DEFENSE games ever created!

4 Star Gameplay Killed by Ridiculous IAP

This is a moderately entertaining 3D Tower Defense game that is absolutely ruined by the wide array of unethical tricks and constraints the developer attempts to pawn off as gameplay. EVERYTHING in the game, despite ALREADY paying money for the supposed "premium" version, requires the game currency of crystals, which are given out in such small amounts upon winning a level, that it becomes virtually impossible to progress to the final levels without spending real world cash. To make matters worse, the developers updates are actually altering the game to INCREASE the reliance on IAP, changing the previous card combination system (which dictates tower upgrades) so that it is even more obtuse, illogical, and unrewarding. The developers should simply become petty criminals and muggers instead of scamming the App Store consumers. AVOID THIS GAME.

Fun and Challenging!

Defense Technica is a fun and challenging experience. It's lots of fun trying to figure out what the best route to keep the waves of enemies away from your core. It's also gratifying when you gain access to stronger towers and you crush enemies (especially big mechanical ones) that have been giving you heck for the longest time. My only gripe with the game is I wish it had more stages. It took me a while to get through the campaign (20 stages), but I have been having so much fun with the game that I I want more. Hopefully a sequel is in the works!
