For many players, Multiplayer is the crux of the Call of Duty gameplay experience, and Call of Duty: Modern Warfare III is no different. Launching with over a dozen game modes across 16 classic 6v6 maps, three 32v32 Ground War maps, and one War mode map, the Day One content offering is staggering.
With Squad Fill toggled off, you'll only drop into the game with your current party which means you'll drop in by solo if you're alone. Just make sure you toggle on third-person so you can watch your own back next time.
