I suppose the 5th world is the Tower, though that's still on Earth I suppose!

4 worlds is super disappointing. Surely we saw more than half of cosmodrome?!

...and there's 2 dlcs coming up.

@kenshi:

Nope, if you look at the maps, there's a huge area in the north that we didn't have access to that's almost as big as the area we did. Half may be pushing it, it might be more like 3/5ths 2/5ths, but it's still a big chunk.

The 2 DLCs add more story missions and raids and stuff, but they don't actually add any more large open world areas. More like adding dungeons.
