thanks for the replies....i like it coz i play it with my friends and we find it thrilling when the tank shows up or when we hear a witch nearby....but i would not play it alone coz i find it boring that way.... im not good at 1st person shooters so my friends always come to the rescue....i think they wanna play with me because of that hehehe...it is way beeter to play l4d with friends that alone
