Really? Haven't seen much of that. Only people who run way ahead or don't use VOIP. But 90% of the time I play with friends. Tip: only play with buddies, and if you play with pubbies who use VOIP and good teamwork, add those to your friend list. With any luck they regularly play at the same time as you do.
I finished my second campaign yesterday!
Yes, only my second... but I only play on Expert. It's pretty cool, because I almost always play with SiC and Kettch and we continue where we left off the last time, that way you get a sense of continuity. You're playing the campaigns together.
Been playing some Versus too, and while it can be fun (especially with friends), I still prefer the campaign mode. I want to finish the other two first. On Expert of course, anything lower is for pussies.
