Left 4 Dead 2 is playable on the showroom floor of Comic-Con, and people are playing it. People are then filming other people playing it, with special attention paid to the new stuff. Boy, those melee weapons look messy.
all this arguing is making me confused.
i just wish valve were honest from the start and told us that they were going to release a L4D2 before the first one came out then I could have weighed things up and thought "well, do i want to play it now or can i wait a while for a better version?"
