Because sometimes the tank music doesn't kick in until well after I've been walloped by it, I figured I'd test using the captions. I completely ignored them.
Played single-player NM5 to test it. And either my computer is retarded, or I don't know how anyone can even remotely suggest the AI is competent. I could make movies everytime I played showing how stupid they are.
#1)They never follow me, they always protect one another. #2)They'll never shoot an infected off you at long range (assuming they even care... they're not leaving their AI pals if there's a single zombie in their area), they run and then melee them off #3) Which wouldn't be bad, but they never run ahead. They're programmed not to run ahead and leave you behind. And they won't leave their AI bots behind. So that means you have to run ahead, alone, if you wanna get anywhere.
Which gets me to the quick round I just played. I'm on the rooftop by the final ladder up. I started climbing towards the roof when I look behind to check. Not coming. So I wait. Finally 2 of the 3 make it to the final ladder. But francis is one ladder behind. And he just sits there. Gets jumped and the AI bots go down and rescue him before they come back up. But not Francis. He continues to stay there. So I climb the final ladder onto the rooftop. Zoey follows. One stays a ladder below. And francis is still two floor below. He's jumped again. And a bot rescues him. And yet he still won't climb that ladder and is two floors below. So I jump off the roof and am on the NM roof main playing area. No way for me to get back down where they are. And Francis still won't climb that ladder. So he gets smoked and smoked, until the bots climb down the ladder to rescue him. And I'm just sitting all by myself exposed, unable to join them even if I wanted to. Really, I haven't seen such crappy AI in a game since the Battlefield series.
