How to unlock the Rotten Inferno Camo
Season 2 of Modern Warfare 3 gives players a chance to put the fiery, burning souls of hell onto their weapons. This is how to unlock the Rotten Inferno camo in Call of Duty Modern Warfare 3!

How to unlock the Rotten Inferno Camo
The Rotten Inferno camo is the new seasonal camo highlight in Season 2. For those acquainted with prior MW3 seasons, seasonal camos are a coveted long-term reward earned through the completion of Weekly Challenges. Each week unveils a fresh array of challenges across multiplayer, Zombies, and Battle Royale modes. There are seven total challenges for each game mode that unlock rewards, typically blueprints or newly released attachments.
To attain the Rotten Inferno, players will have to lock it in across the eight-week Season. Each week players will have to complete five challenges in a game mode to unlock the weekly reward. Fear not if a Weekly Reward eludes you; redemption remains feasible in subsequent weeks. At the end of the season, once players have unlocked the reward from each of the eight weeks, the Rotten Inferno camo will unlock. It is a long road, but the journey is worth it for this blazing reactive camo.
