One player can select the "squads" that will serve as their playable characters in the game. These characters include Jackal, Genie, mite, and Grunt. There are also other non-playable characters that can be controlled through the keyboard. The single player campaign is divided into three parts, the first of which is the "campaign" part, and the second of which is the "Solo Operations" part.
Part of the single player campaign is the "capturing the compound" part, where the player's chosen playable protagonist must successfully defend their base against waves of attackers from the attack team that just attacked. The British DPM Company, under the command of Gen. Alexander Cross, sends two groups of their armed forces to attack the U.S. base. The offensive team is composed of grunt forces that utilize anti-tank weapons to take down the armored troops, while the counter-offensive team is comprised of snipers that must protect their position from the enemy.
