PlayDevil has posted a review of the XBLA game "Defense Grid: The Awakening" from Hidden Path.
Is it the best Tower Defense game ever for XBLA?
Here's a snip from the review:
"As with all tower defence games the concept is simple in that the enemies enter the screen at one point and exit at another. It is the players task to repel the enemy attack by strategically placing towers to stop the enemy in their tracks. Defense Grid however offers some nice variation by having the game taking place on a space station with an excellent variety of aliens attacking your base to steal energy cores."
