If there was a new faction added to PB2/PB2.5 what would you want it to be? Which factions would it be allied with? Would it be neutral? Or kill everything? Focused on vehicles? Or soldiers?
Personally, I would love to see a Rebel faction, using outdated weapons and stolen weapons, not only would this be a unique faction but it could provide lore as to why we fight the Civil Security, as well as open up a bunch of options for the level editor (aka the weapons and skins).
