Defense Grid

So Ive been playing Defense Grid: The Awakening for quite awhile now and I have to say it is a great game. Ive been playing Tower Defense games for a long time and this is quite honesly one of if not the best I have ever seen.

For those of you who dont know. Tower Defense games basically revolving around enemies of some kind following a path from a start to a finish point. Along this route you place towers in strategic locations to kill them before the can make it through. It sounds simple to learn, and it is, but figuring out which combination of towers works the best can make this very difficult to master. Well worth the $20 it costs via steam.
