SOS Missions are a unique, pseudo-multiplayer feature in Sonic Forces. Occasionally, you'll see an 'SOS' icon appear over a stage on your world map. This indicates that another player's Avatar is 'in trouble' within that stage. By completing the SOS Mission, you effectively 'rescue' their Avatar and are rewarded with a unique clothing item that often belongs to the rescued Avatar's set. This system encourages community interaction and provides a fun way to earn rare cosmetic gear.

How SOS Missions Work:
- Appearance: SOS Missions appear randomly on stages you have already completed.
- Objective: The objective is simply to complete the designated stage. There are no special conditions beyond finishing the level.
- Character: You will play as your own Avatar for SOS Missions.
- Rewards: Upon successful completion, you will receive a piece of clothing or an accessory that the 'rescued' Avatar was wearing. These items can sometimes be exclusive to SOS Missions.
- Frequency: SOS Missions appear periodically, so it's worth checking your world map regularly.
While you're not directly interacting with another player in real-time, the system creates a sense of shared experience and community. Rescuing other Avatars is a straightforward way to expand your own Avatar's wardrobe with unique and stylish items. It's a low-pressure activity that offers tangible rewards, making it a worthwhile endeavor whenever an SOS icon appears on your map. Don't miss out on these opportunities to collect rare gear!
