I got tired of the tank a the start, so it's gone. Also lost the HEMTTs at the start as they were only blocking the view now that the tank is gone. Some percentages dropped down a bit, friendly tank comes online 10 seconds earlier, and a half dozen less guys on the heaviest spawn. Rest the same.
Test round got me 303 kills to finish, tank had about 40 of those.
Download from map cycle - it's the new one.
