I'm seeing quite a lot of negative reviews here due to the state the campaign released in a couple of months ago. And although most of the points mentioned are totally correct and the campaign is dissapointing compared to what came before, the survival mode itself is such a unique RTS experience that I think it's easily worth the admission price alone. I spent well over a hundred hours in the game and finished it on the highest difficulties before the campaign was even out. Players start out with just a HQ building, 4 basic units and a few resources, surrounded by a horde of zombies. To claim additional land and resources for growing the colony, players must clear out the roaming zombies in the vicinity. You can't just apply brute force however, as attacking units generate noise and the more noise you generate, the more zombies will be attracted to your position. The whole game is a fine balancing act between growing as fast as possible to resist the ever growing waves of zombies, while not attracting so much attention as to get overwhelmed. It's a unique gameplay mechanic which I haven't seen in any other RTS before and is highly fun and addictive. Yes, you will lose many, many times before you will win a game on the higher difficulties, but when you finally do, the satisfaction is unparalleled. From a technical standpoint, the game sports a very impressive engine, capable of handling truely insane amounts of units on screen without tanking the performance much. Seeing a wave of literally thousands of zombies charge your walls, soldiers, snipers and automated defences mowing them down by the dozens is a cinematic experience all of its own. If you've ever watched the Walking Dead, World War Z or one of the other countless zombie movies and thought you could do better than the survivors in those worlds from a strategic standpoint, this game is for you!
