Shanghai Summit addon

Here's an early screenshot of the next release.

Old screenshots shots below.

Old Notes:
Parts of the map have been closed off to tighten the game play up a bit, but I plan on opening up more of the playable areas during the second phase of the #grindhouse mapping contest. There are a few little problems that i didn't notice until after i submitted the map for download. Like a missing texture/mesh and a buggy path node (near the uphill road at the start) where a rogue zed gets stuck on once in a while. So hopefully I can get the updated version of the map up here soon... I hope you guys like it! It's not much at the moment but hopefully it'll improve over time. :)
