The game also became available on Steam on November 6, 2007 for pre-purchase and was available to play as of November 12, 2007.A Mac OS X version of the game is scheduled to be released in May 2008.Call of Duty 4: Modern Warfare focuses on the progression of warfare as a contemporary infantry soldier; presenting the player with a vast number of different combat scenarios unseen in prior Call of Duty titles. It strays from the constant assaults, interspersing high-intensity fire fights with slower-paced drama and suspenseful clandestine action. The series’ move to modern warfare introduces a variety of new weapons and technology to the Call of Duty franchise. Such showcased equipment includes the M203 grenade launcher, M4A1 carbine, the AN/PEQ-2 Target Pointer for use in conjunction with night vision goggles, the MP5SD submachine gun, and the FGM-148 Javelin portable anti-tank guided missile, among many others.

The game moves away from the prior three country-specific campaign style; the plot remains cinematic, with story lines interlaced from the perspectives of members of the British Special Air Service and United States Marine Corps Force Recon.
