Anytime i try and join a server it just immediately says "connection with session has been lost". Like literally as soon as i click join. Doesnt even seem to be trying to make the connection.
This is a bug at the moment if you try and join a FINALE level. I had it last night while trying to join friends. As soon as they are done and are back in the lobby you can join.
Getting it permanently...I'd look for help on steam forum.
Well I played the full game after getting home last night....WoW. It bascially had the draw of the demo when it first came out!
I managed to play a whole campaign of "Blood Harvest" with 3 mates on advanced. Great fun, died once on the FINALE but we sorted out our tactics and it was all good!
That level was cool as hell, quite long and much different to No Mercy.
I also played an hour or so of .VS. mode on a server with some decent guys. So much damn fun.
You play the round as human to start, do what you can and see if you cna get to the next safe house. Then you switch and the undead go survivor and vice versa. It spiced up the No Mercy campaign loads!
I'll stress what someone else said above though, which is horde MUST work together otherwise you run out and die instantly. We had a hunter and smoker working to pull someone miles and puke on him. Also two hunters working together works great if the group are quite seperated.
Playing the Tank is GREAT but the HP seems less than the CO-OP tank has and I didn't seem to do much damage. I chased the woman from full HP to knocked down on the ground RED HP. Hit her about 7/8 times in a row on the ramage and she still lived...bit dissapointed.
Other than the above, can't wait to see the other two campaigns and play them all on expert and have more fun on the VS mode
Edit: I also recomend the Hampshire Heavies L4D community. Loads of members and they have 5 servers up at the mo. 3 COOP and 2 VS I think. Search them on google!
