I think one fix could balance game for solo/teamplay. I don’t mind the difficulty. What I do mind is the neverending stream of bullets tossed at you by robots. That mechanic throws steath and strategy out the window. Maybe robots run out of ammo and have a re-supply robot they need to access? While they are in the process of re-supply you could target them or take a chance at destroying the re-supply robot.
What a cool idea! Sounds awesome. Considerably more realistic and it would really open up a window for the player (especially solo players)
