EquipmentLate
Ultra High Capacity Air Tank is an equipment item from the launch-build item set. Use it as a progression checkpoint before longer trips, because equipment items usually change oxygen budget, movement, survivability or vehicle readiness more than they change the map itself. Its current recipe-graph tier is late, which helps separate starter checks from later crafting goals. Use the related panels on this page to move between ingredients, recipes that consume it and nearby items without turning unverified coordinates into map claims.
