Tennis 2016 is a smallish death match map which features a tennis court area, spectator areas and corridors connecting the two spectator areas.
It has plenty of weapons and items, some tennis related pics and sounds and even a cigarette machine and a coke machine in case you get thirsty whilst fragging :)
Just unzip all files to your Kingpin folder and they will be placed in the correct locations
It's a very popular map and is loaded on several Kingpin death match servers.
There is also a Bagman version of this map available here Gamefront.com
