Remastering
"The Doomsday Device" was heavily remastered in May of 2011. Additions included an new introduction with the boarding of the, cutscenes, several accolades and many new gameplay mechanics.

The remastered version originally created a continuity error, as it featured B'vat despite his character having been killed off in. This was addressed in Season 5: Call to Arms, which restored the Klingon Front missions to the original (pre-launch) order.

The mission was reworked once more in Season 15, with the removal of the career-specific objectives while repairing the Targ, fixing the map display from the first portion of the mission and working on the trait reset bug. A later update in Season 15, on January 10, 2019, the cutscenes were updated with improved animations.
