3zb2 file

Extract this archive in your Q2RTX folder. You should now have a '3ZB2' folder in your Q2RTX folder.
Go into your 3ZB2 folder you should find '3zb2.cmd' file. Execute it to load the 3ZB2 mod.

Once the game loads, in the console type 'map q2dm1' for instance, to load Q2DM1. Once the map loads type 'sv spb x' where x is the number of bots you want to add. There is an extensive readme file and a user manual redacted by the original mod creators.

All credit goes to the original mod creators. I only built a binary (gamex86_64.dll) that is compatible with Q2RTX.

Enjoy !
