Hmm...
Well, it's basically a turn-based flash version of Call of Duty 4 (which happens to be like crack for me) so i can't say it's that great in comparison - the guns, the 'perks', the level system, and even the story mode come straight from CoD. Don't get me wrong, it was a good try at a game, but it just doesn't cut it for me.
There were a few things that slowed the already slow game play, another turn off for me. For starters, the action menu is an extreme hassle to go through. Also, I think it's silly that you cant shoot at someone unless they're in range - just make it a less accurate shot. One thing that really annoyed me is that you can't deselect units, which just gets on your nerves. Something i found that is a little strange is that you can shoot through a concrete wall for full damage but can't break through a tree stump in the middle of the map. The last flaw i found is that the enemies respawn regardless of where you are, so, as bohanben said, the enemy just walks up and knifes you, which is kinda stupid if you moved up specifically to kill the enemy.
Other than that, the game definitely has potential to be great, but it just needs some all-around polishing first.
