This patch provides full ioUrbanTerror support, because many UrbanTerror players are using ioUrbanTerror instead of Quake3.
- IOURT4.x as separate game
- URT4.x as q3mod as q3 server
I used the version string of iourt servers to differ q3 servers. It's not perfect and FrozenSands should use their own masterserver version in next releases.
