I found them on one site but there seems to be a bug with their download buttons for both.
The first patch takes the game from version 2.0 to version 2.1 for any licensed version. Fixed Deleted document mapping.txt. Fixes issue with a weapon. Fixed some textures. Fixed problems with sound. And added some features. ETC.
The second patch take the game from version 2.1 to version 2.2.3 for any licensed version. Fixed problems with missiles. Fixed bugs with empty names of players. Fixed broken link in the description. Fixed some display issues. ETC.
Any help finding these patches will be greatly appreciated!
