It can be done! Playing as ithe infected. You don't need a mod, you just need somebody hosting who knows how to switch it on. Will try it later today and tomorrow!
And it's cool. Weapons are way fun. Reverse horde triggers! Instead of setting off the horde, now you have to stop them by turning shit off. Clever. Stops people camping during the trigger points. Love it. Can't wait for the full game. Frying pan is fun :)
You may have noticed already that the [DRY] [KY] server has been running some custom campaigns. The server now links you to a page to get any campaign or map if you don't have it already. Pretty cool huh? I thought so :)
