The decision to keep the episode count low was largely driven by:

Prison Break Season 5 (titled Prison Break: Resurrection ) has 9 episodes .

Availability depends on your country, as licensing agreements frequently shift.

Unlike the original four seasons, which typically boasted long runs of 22 episodes (with the exception of Season 3, which was shortened to 13 due to the 2007–2008 writers' strike), Season 5 was produced as a limited event series.
