What Are Special Exterior Missions in Attack on Titan 3?
Special Exterior Missions are a brand-new feature for the Attack on Titan game series, making their debut in Attack on Titan 3. As the name suggests, they take place in the exterior world beyond the walls — a vast and perilous environment where the threat of Titans is constant. The official description frames these missions as life-or-death undertakings, with the squad operating far from the safety of the walls.
The defining element of the mode is the leader's responsibility. When the overwhelming threat of oncoming Titans closes in, the official Steam description states that whether you advance or retreat is a decision entrusted to you, the squad leader. That single sentence shapes everything else about the mode: Special Exterior Missions are as much about judgment and risk management as they are about fighting Titans.
This is also the first time the series has described a mission structure built around leading a squad into the exterior world with this much explicit decision-making. Together with your squadmates, you carry out the mission, and the choices along the way belong to you.
The Mission Loop
The mission loop is the sequence of activities that makes up a Special Exterior Mission, and the official materials confirm five parts:
- Assembling a squad — you put together the squadmates who will accompany you into the exterior world.
- Constructing supply bases — supply bases are built to support the expedition in the field.
- Managing resources — fuel, blades, and supplies are the resources you manage during missions.
- Capturing territory / expanding territory — the squad captures ground and expands its foothold.
- Retreat decisions — knowing when to pull back is part of the loop.
Each element of the loop is confirmed by the official description, but how the pieces interact in practice has not been detailed. For example, we know supply bases are constructed and that fuel, blades, and supplies are managed, yet the exact way bases affect resource consumption or territory control is not published. The loop is best understood as an expedition cycle: you assemble your squad, build up support in the field, keep resources topped up, expand your territory, and decide when to retreat.
What the loop makes clear is that a Special Exterior Mission is not a single fight. It is a sustained operation that spans squad preparation, field construction, resource upkeep, territorial expansion, and a final decision about how far to push.
Squad Morale and Risk
Squad morale is part of the risk you manage as squad leader during Special Exterior Missions. The official materials confirm that morale exists and that it is one of the things you have to account for when leading the squad, but they do not explain how it works mechanically.
The specifics are "To be confirmed": how squad morale rises and falls, what causes it to improve or break, and what its exact effects are on the mission have not been officially detailed. We cannot state concrete morale rules, because none have been published. This page will treat any specific morale numbers or mechanics found elsewhere as unverified until the developers confirm them.
What players can rely on is the framing: morale is part of the risk picture, sitting alongside resources and the advance-or-retreat decision. When the game launches and the mechanics can be confirmed, this section will be updated with the real rules.
Advance or Retreat
The advance-or-retreat decision is the heart of Special Exterior Missions. According to the official Steam description, when you are faced with the overwhelming threat of oncoming Titans, whether you advance or retreat is a decision entrusted to you, the squad leader. The responsibility is yours, and no amount of preparation removes that call from your hands.
Advancing means pushing deeper into the exterior world, capturing more territory, and expanding your foothold — while staying in the path of the oncoming Titans. Retreating preserves the squad and the resources you have gathered, but it can mean giving up ground you had started to take. Because fuel, blades, and supplies are consumed during missions, the retreat decision is also a resource decision: pressing on costs more of what the squad carries.
There is no confirmed rule for when retreat is the right call; the official materials deliberately leave that judgment to you. The life-or-death framing of the missions suggests the stakes are high on both sides of the choice, and the decision is presented as a genuine test of leadership rather than a scripted outcome.
