Andrew never shoulda let you play through on Hardened. I don't necessarily know that would've made that much of a difference, but still. Never shoulda let you.
I blew through COD 4. I still haven't beaten World at War. I could probably go back and beat it, but the level I'm stuck on gives me serious roid rage.
I never really got super mad at this game. One part pissed me off royally and I screamed and threw my controller up in the air and caught it, but that was it. Otherwise, I was just fuckin whipping ass.
