Game director Justin Richmond told Eurogamer that the desert setting of Uncharted 3: Drake's Deception will provide the new PlayStation 3 title with the largest landscapes seen in the series to date.
Mr Richmond said this will make the game feel more open "for sure", but was also keen to stress that the team has taken care to ensure this does not transform Uncharted 3 into an open-world experience.
"We're never going to be an open-world game, just because that's not what we're interested in making ... we're never going to let you just ride a thousand miles off into the middle of nowhere," he said.
Uncharted 3: Drake's Deception was announced earlier this month and will see hero Nathan Drake seeking out a lost city in the Arabian desert.
Gamers will be hoping it can live up to the standards set by the first two games, which have proven popular enough to spawn an upcoming film adaptation starring Mark Wahlberg.
