Favourite TF2 Custom Map

[Breakdown]

Title explains it all.

There are lots of custom TF2 maps, what's your favourite??

At the moment, mine is Balloon Race, there is a server that plays it all the time, it's really fun when you get the hang of it

I also really liked ctf_vikings, but the server that played it 24/7 isn't around anymore, so yeah...

And of course, gotta love the achievment servers xD
