In L4D2, can companions be ordered to take actions?
Me and a friend have been playing. That means 2 of our slots are human and 2 are AI-controlled. We are primarily interested in giving 2 orders:
How can we order a particular companion to follow one of us while the other follows the other one of us?
How can we order a companion to pick up an item? We've noticed that they don't like picking up any extra medkits at the start of a level which we can deal with, but what about telling them to replace their weapon / medkit / pain pills?
We've tried using what seems like a command system (Look, Let's Go, Hurry!, etc.), which causes the AI-players to make verbal responses, but doesn't seem to affect them in any way other than that. Unless we are doing it incorrectly, of course.
