I know there are quite a few of you are waiting for the map release so you can go kill zombies at the Highball. I have been working on the map every night to finish it out. I have added a few new assets from The Sacrifice update and currently 100% of the map geometry and all the details are done and locked in. I just have a few bugs that affect scavenge mode to figure out and then I will release the map.
Also, Left4Dead2 is still less then $7 right now, so if you want to play this map that is a low price to pay.
In the mean time please enjoy some of the final screenshots:
