I get why the strikes are 3-player. To some extent I even understand why the story missions are too. But why explore mode? Especially when there are public events.
They probably won't raise it and I have no idea why its only 3 players. But it seems 3 is a design choice. 3 astronauts on mars, 3 classes and races. Idk of the 3 goes any deeper then that, but maybe it plays a significant role in the lore or something
