Don't worry on it. I'm having fun for the most part. I don't have the hang of heroes yet - sometimes I am deadly and other times I just suck. Then again, it's like that for almost every mode. heh.
No problem. I got a bit pissed they weren't spawning Heroes. I finally quit 'cause my aiming was **** - like my system was always behind. But I would have quit anyway since those pricks were not spawning. That's why I prefer black box.
