Have you ever wanted to play a multiplayer game that feels like a mixture of Left 4 Dead, Prototype, and Rainbow Six: Siege? No, you haven't? Well, I'm going to tell you now that your shortsightedness will curse you. It would also curse me because I didn't think I wanted it. After getting hands-on with Tom Clancy's Rainbow Six Extraction, I can't deny that I like it. I'm not going to say that it's perfect, and I didn't get to try every single map, so there are things I don't know, but I got to spend an entire morning with the game.
