Call it beginner's luck: my first round of XCOM: Enemy Unknown's multiplayer was my strongest showing. It came down to a tense showdown at the end. I lost, but could feel proud of how close I had come. Alas, that was my best performance. From there, I got my rear end most thoroughly handed to me.
I got to try out the game at Firaxis last week, with a handful of other writers. There is only one multiplayer mode, and it is a brutal deathmatch. Two players each build their own custom squad of six and then hack away at each other—and at the destructible environments—until only one remains.
