Right now there are 2 new open buildings in the mod. The bank (made by me) and the gas station (made by MikeyPI). These open houses take weeks to create each. You don't want to wait for that. That's why I've planned to do these kind of time-consuming things after the first release of the map.
Right now, I'm finishing Voodoo_Operator's stripmall. When that one is finished I will make a new update post with screenshots. 
ok cool, thanks for the information, but I have just one last question, I noticed that in the normal freeplay map, There is only one hazmat call, and i was wondering if you were going to put more hazmat calls in the new map (maybe one with the canister from the hazmat mission)
