Step 1 (Play through the campaign on Hard):

An online version did exist but has now been withdrawn. Like with many recent games, Warfighter forgoes including a game manual in the case. While online you can choose to play as a member of over a dozen real-life highly skilled international fire teams in the fast paced competitive team-based multiplayer modes. During the campaign you will play as and alongside the elite Tier 1 force while completing missions inspired by real-life counter-terror operations. Warfighter was written by actual Tier 1 military Operatives.

This modern military shooter isn't only about what current soldiers are up against, it also reminds you of what they're fighting for.
