Still only on the Earth and Moon, trying to level up, keep doing random missions for XP and Valour points.
Quite a lot of my friends list are on it.
The ability to save random players is good, as are the special events.
The maps are pretty big and complex, I still get lost in the Russia map.
A pop up map would be nice, one you earn like in Borderlands 2.
Now as to its single player longevity, hmm better than quite a few games, but less than a good RPG eg Fallout 3/NV, and it still is not as good as Borderlands for fun. 3 classes, 3 species, 2 sexes.
Co-op is good if they do not run off while you are looting.
Writing is OK but nowhere as good as say Naughty Dog.
Solid 7/10 game.
Enemy AI is not great, Most places you can hide behind cover, they respawn quickly for farming.
Inspirations I have found are looting and fire teams, Borderlands. Drop in co-op Journey, general feel Starwars.
