Played the demo AND...Its cool
IT really depends on the team...i played with a friend and his friends on hard and we slid through the second level in 10 minutes encountering 2 witches (now scarier then hell) 2-3 jockeys, 2 smokers, a tank (boomer bomb FTMFW), a charger(i got hit but he ran through a hoard of zombies and nearly took out half of them), and a boomer and we all got to the very end of the level before one of us (Me) died to a spitter ambush and the other guys abandoned me justly because if they tried to save me they would have gone down as well.
on my 3rd time through i went with a random team 2 who never played a l4d and one who was a expert at l4d1 (and takes the Slow and steady method) needless to say because i was the one that was doing the most assists and stuff i was the one most targeted by specials The teammates never helped me intill the 8th time we failed and they realized that every man counts.
The number of ways I and my teammates failed
they didn't run on the crescendo bit while i ran almost all the way before a smoker got me.(teammates)
Boomer bombed a witch to get through to the safe room (we survived but it was very noobish)
Everyone but me grabbed the hunting rifle and shot the hell out of the horde that i was shotgunning though (death by teammates)
Boomed then jockeyed then charged all with in 10 second of each other while my teammates RAN AWAY! Died and then guy with the Defibrillator Comes up and grabs my health pack. (both and yet more of the teammates fault)
died while i was healing (i had 10 health left) because the guy that was "protecting" me ran off to grab a guitar then came back and grabbed my health kit!(teamwork fail)
spitted, boomed, and smoker'd in the crescendo event 3 feet from the button.(me and my teammates BECAUSE THEY STAYED IN THE VAN!
