The infection update now lets the round end once the infected in the phaeton is killed! Also the gametype has been adjusted to give survivors no ammo (well one bullet) for the starting weapons. This means survivors will either hide for the first 2 minutes, or rush the big guns to get a head start on killing the infected. In the last minute all survivors become last man standing with infinite ammo, and their positions are revealed. If you can make it to the last minute of the round, fighting back is your best chance of survival.
Also the framerate appears to be slightly improved since I last played it, but I'd still recommend no more than 12 players unless you are ok with the framerate dropping. I don't plan on adding much more to this, but I am strongly considering making a similar style map. Any feedback is appreciated.
