There have been a few parts where you're split up and I've wondered if Sidekick was invincible at those times. When we're together he seems to drop really quick, usually stepping out from around a corner to fire at someone that's clearly behind cover. The best place I've found him dead was lying on top of a pile of fragments from exploded barrels.
He does take cover, but he doesn't seem to like to stay in it and he doesn't seem to like to blind fire.
Which level are you at now ?
In KZ2, I don't stay behind cover or at least the same cover too. I certainly can't blind fire. I move constantly to reset their AI states. I am usually in front of the friendly AI. When I stay behind them, it's because I'm recovering.
In Resistance 2, I stayed behind the AI instead (because they are invincible).
The AI hasn't really hindered me, but it hasn't helped either.
Yes, it certainly sounds like you're not able to exploit the friendly AI effectively because they are not invincible like many other games. Usually when Garza or Rico exposes himself, I'd snipe the enemies one by one, or flank them. When I played the first 3 Veteran levels, I distinctively remember Garza being a great help. e.g., When destroying the lightning gun, he informed me whenever the cannon was exposed. This allowed me to toggle between the gun sight view and the hip shot view quickly. He was also able to pick off the incoming enemies from behind cover when they charged towards the cannon. At that time, my aiming was still abyssal for targeting running enemies.
I also find them useful for identifying flanking units. When I stayed near them, they'd usually notice where the enemies were faster than me. In actual combat, I'm usually all over the place.
Never noticed. I'm pretty sure I killed Rico enough last night that I should have found out
There is a video on this. Let me find it. They may forget about attacking you if enemies are present.
EDIT:
You could make a whole meta game of Elite difficulty by trying to keep your partner alive. It's like they hate life and just want it over with.
Ha ha, yeah Elite would be different. I don't intend to play it unless I have a lot of time on hand.
