Likewise I’m sure they had a great reason for considering it in the first place, but to me it sounds like a horrid idea. I don’t mind when characters can interact with each other (like tossing ammo, or using items on each other), but not in a sense where you need both players to … “physically” work together to complete a simple task. This is a very vague statement because I’m not sure how to explain it in this context. Eh, I guess, imagine if you tried to toss ammo to someone by pressing the action key, but at the same time they had to press the action key to catch it…
Anyway, being able to pass through other players is easily a good feature. Realistic/simulation games where you get stuck on some guy who is prone in front of you and you can’t even walk or step over him? Ugh!
