Would be nice for all 3 factions or two being present on planet and maybe fighting with each other with different detectives for H. D2. Also why second arm can not be customizable and why deployed weapons such as machine gun to lvl up...eg nice if they would be too better handling and reloading for example
Helmets and capes could be with bonuses
And of course more missions...you can throw couple o to dozens missions to create diversity... Not all ppl are robots who like to do it all over again and again...
