Call of Duty 4: Modern Warfare Primer

By: Matthew Rorie

Infinity Ward isn't necessarily the most adventerous game studio out there; after breaking off from the development team that made Medal of Honor: Allied Assault, it went on to make two more World War II first-person shooter games, Call of Duty and Call of Duty 2. Both were exceptional, but they also helped form a glut of WWII shooters that practically drowned consoles and PCs in the early part of this decade.

Now, though, Infinity Ward has updated its game engine for next-generation consoles and has also updated the setting. Call of Duty 4: Modern Combat takes place in a contemporary setting, with real-world guns and a taut storyline that draws upon the issues of the day. It's not going to revolutionize the shooter genre--in the end, you still have to point and shoot--but it's a welcome departure from the world of potato mashers and MP44s. (Well, mostly…)

GameSpot's Primer to Call of Duty 4 isn't intended to be a full game guide with a walk-through and all the works, because the game is pretty simple to play, so long as you can point a gun and pull a trigger. Instead, here's what you can expect from this primer:
