This game lacks the depth of a good tower defense game, anyone that is a fan of the genre will be utterly disappointed.

User Rating: 1 | Defense Grid: The Awakening PC
Tower defense games can be extremely fun, thousands of players still play Starcraft and Warcraft only to experience the user-made tower defense maps that thrive in the bnet community. In comparison, this game isn't worth the time.

-no multiplayer
-only tower auto targeting, not even attack ground.
-very limited maze abilities.
-uninspired enemies
-awful control for PC
-fast forward time button (they realized their game is boring half way into development)

The developers for this game didn't invest enough time into research and design, they left us with an empty 3d game that will bore you in the first 30 min, considering all you had to do in those 30 min was set a couple of towers and go AFK.

If you don't own warcraft or starcraft and want to experience a tower defense game, google Vector TD and play it for free, you will have more fun, guaranteed.
