The guide follows the single player campaign, with a team controlled entirely by AI. In multiplayer, some battles with obviously take a different turn, depending on the abilities and decisions made by the other players.
Most standard items, such as armor pieces, med-packs, or ammo, pop up in random places. As a result, the guide doesn't specify their locations, which means you'll have to scan every newly unlocked area on your own.
For easier orientation, all secret items have been marked in green. These include Dog Tags of fallen marines, Audio Logs, and the so-called Legendary Weapons. You can follow your progress in finding them by opening the current mission objectives screen. Full statistics are additionally displayed at the end of each main mission.
