In the Uncharted series, protagonist Nathan Drake gets a lot of bumps and bruises to help offset his rugged good looks. But, according to the team over at Naughty Dog, there’s one injury that he’s never had — a bullet wound.

According to animator Jonathan Cooper, when he joined the team at Naughty Dog one of the first secrets he was let in on was that in Uncharted 4: A Thief’s End there’s no damage indicator. Yes, there’s a red indicator at times when Drake starts taking accurate fire, but it’s not a damage indicator. Instead, it merely indicates his luck running out.
