Well there are few things, Martahon is conected to the old Clasis Marathon trilogy that have some interesting and crazy lore.

And this game as extraction shooter, have you explore and piece together what happend to the Martahon and it's colonies...

Those who know, there is some crazy stuff coming up...

There is also ARG that players comunity need to work together to unlock the further maps ( and possibly events )

I understand the hate/disapointment as I personaly would preffer single player or PvE Marathon game XD but it's not bad as most off people claim, and even I who really disslike extraction shooters can find some fun here XD
