Edit: The Save System for UFPS was just released on the Unity Asset Store. This asset work similarly to the Save System for Realistic FPS Prefab, but it applies to Opsive's UFPS. If you use the Dialogue System in your project, you don't need the Save System for UFPS. The Dialogue System includes a UFPS integration package.
