Lol, well what can I say? Inferno is a good map. :P
Yeah Survivor usually only wins the vote when there are LOTS of people on the server. Addon maps are always like this. I remember I couldn't get ANYBODY to run de_vegas_css when I released it, but a couple months later, it was all over the place.
You just gotta give people time to learn wtf the map is, then they'll start voting for it.
Making your gun do 10x more damage than the default? I have **no idea** why that would be considered a hack, lol. I like to mess around with the scripts too, but it's a good idea to keep a backup of the original, and use the new one for bot matches.
