Liberty Day

"'Liberty Day is celebrated on the 26th of October.' - Loading Screen Tip"

Liberty Day is a holiday of Super Earth and is celebrated every 26th of October by the game's developers, Arrowhead Game Studios, and its fan base alike. Historically, Arrowhead Game Studios has published an official blog post each year recognizing Liberty Day and has been known to hold interactive events such as live streams, contests, giveaways, and an "Ask Me Anything" (AMA) thread. Members of the fan base often celebrate in ways such as by participating in these events, sharing Helldiver-themed media (such as photos) online, or simply playing the game even after an extended hiatus.

Each year on Liberty Day, the game's title screen displays fireworks while the ticker on the ship reads, "Humanity everywhere rejoices as we celebrate Liberty Day!"

Liberty Day Content Updates
Arrowhead Game Studios has not released new content additions every Liberty Day, but they do have a record of releasing such updates in the past. These updates are not guaranteed nor have they been publicly announced in advance, however, they are free updates to anyone who owns at least a base game copy of HELLDIVERS™.
