Kingdom Come: Deliverance 2 is a first-person experience, and that's by design. If you're hoping for a third-person perspective, you'll be disappointed. The game, excluding cutscenes, is entirely played from Henry's first-person viewpoint.
This design choice is intentional; the developers aimed for maximum immersion, believing the first-person perspective best allows players to inhabit Henry's role. While the modding community might eventually offer a third-person mod, the base game remains strictly first-person.
Cutscenes and conversations offer glimpses of Henry. The camera shifts between Henry and his conversational partners, and his appearance changes based on dirt accumulation and equipped gear. However, during exploration, the first-person view is constant.
An official third-person mode is highly improbable. Therefore, if you plan to play Kingdom Come: Deliverance 2, be prepared for a fully immersive first-person adventure. Check out The Escapist for additional game tips, such as optimal perk selections and romance options.
