Now that the 1.0 release was confirmed for December, let’s theorize what those DLCs could be:
.: Blood And Titanium
Probably this will be the floating base, judging from the initial campaign end goals. Maybe “titanium” refers to the structure itself, and “blood” to the lifes of everyone lost to build such a structure.
.: Legacy of the Ancients
With a name like this, it has to refer to the first race of Earth’s hominids who managed to defeat PV, so I’m expecting a much more lore focused DLC. And, yes, the search for the Ancients will be done underwater, hence underwater missions;
.: Festering Skies
Yeah, most probably the aliens take the fight to the skies, which up until that point was mankind’s main advantage. PV recognized it as such, and evolved to counterattack.
