The multiplayer mode in Brothers in Arms: Hell's Highway consists of three maps with capture-the-flag style objectives. You play on either the offensive or defensive team, with the offensive team's goal being raising a flag at a certain point to win. The defense, conversely, tries to eliminate all the players on the offensive side - when all the players on either side are dead, that side loses. Players get one life per round and upon death go into a passive spectator mode.

Multiplayer mode features squad-based combat imitating the single-player's teamwork-oriented gameplay. In multiplayer, there are four squads to join: a leader squad that can set down markers to guide his teammates, a normal squad with regular weaponry, a special squad that can carry either bazookas, sniper rifles, or heavy machine guns, and a tank squad.GameFAQs: Brothers in Arms: Hell's Highway Multiplayer Discussion
