Helldivers 2 already had democracy in spirit (my democracy officer, who is definitely not standing over my shoulder with a gun, tells me this) but now it has democracy in practice.
After a gauntlet of major orders, a feature so thoroughly anticipated that it encouraged players to form the Freedom Alliance, the Democracy Space Station (DSS) has been deployed.
This thing is actually way more than just some flavour text for your next major order—it's a whole new game mechanic, and a great place for already kitted-out divers to spend their hard earned resources.
Once every 24 hours, the divers of Super Earth can literally vote on a planet for the station to be redirected to. Once there, certain actions—purchased with heaps of samples and requisitions—will bombard whatever imminently liberated planet the DSS is dispensing democracy over.
Now, it's not clear whether this aid will make missions easier or harder, but who cares. More explosions! Do you wanna live forever?!
