Unreleased Helldivers 2 vehicles are leaking all over the place, but I'm not ruling out that Game Master Joel has something to do with it

The Super Earth mothership is springing leaks. Developer Arrowhead Game Studios has talked openly about how unprepared it was for Helldivers 2's massive popularity at launch, so it's fair to assume it also didn't anticipate how motivated fans would be to find out what's coming next.

Far and wide, players are joining quickplay lobbies and discovering teammates piloting walking mechs equipped with machine guns and missile launchers.

That could explain an uptick in mech drops. If Arrowhead were slowly doling out mechs to random sessions, it'd accomplish two things: gathering
