Single player game that works like a mix of Shadow of Mordor, Dark Souls, Arkham series and Monster Hunter.
You make your own Pred, choose his arsenal, has a story mode in a main planet but you are also able to take your ship to other planets for side stories and to hunt specific creatures similar to hoe MH lets you go to different mini open zones. Nemesis system would work perfect here too, Souls like system for a more realistic combat approach, except this time you are the boss.
