Citing numerous "trusted sources" close to Naughty Dog, IGN reports that Hennig was writing and leading the development of the next instalment of the Uncharted series for PlayStation 4 before her final day with the developer on March 3. According to IGN, sources claim the creative director was "forced out" of the company.
