Climb, also known as Kreedz (KZ) in CS 1.6 and CSGO, or Xtreme Climb (XC) in CSS, is a popular community game mode found in every Counter-Strike game.
Climb is a series of platforming challenges that can be best simplified as “trick jumps” which pull from the big 3 movement disciplines in source:
Strafe, Bunnyhop (Bhop), and Surf to challenge players in scaling its maps as fast as possible.
Porting maps from Goldsrc to Source is not easy. Depending on the complexity of the map, be prepared to invest anywhere from 3 to 50+ hours into a single port. Prior experience with Valve’s Hammer Editor is helpful, however porting maps is entirely doable without ever having used Hammer before.
This guide was primarily written in July of 2025. There is a small number of people who occasionally work on tools for the GoldSrc porting process, so depending on when you are reading this there may be some new ways to make the process easier. Search the web or ask in the Momentum Mod discord and you might find something useful.
