Love the game. Simple controls are easy to use once you learn them. Best part is you can advance at your own pace. It's a survival game at its best, and it's not a mindless, no thinking involved, non-stop shooter. Great one player, no hassle, no dealing with foul mouthed kids online game. If that's what you're looking for, there are hundreds of those out there. Thankfully, this is a great stress free thinking game.
