CS 1.6 KZ and Bhop — Kreedz Climbing & Bunny Hop Explained

Kreedz (KZ) climbing and Bunny Hop (Bhop) in Counter-Strike 1.6 — long jump, duck jump, air-strafe, timers, records and where to learn the movement.

Updated: 2026-07-30

KZ (Kreedz Climbing) and Bhop (Bunny Hopping) are Counter-Strike 1.6's two headline movement disciplines. Both grew from the same GoldSrc physics quirks that made surf possible, but where surf exploits ramp acceleration, KZ and Bhop exploit air-strafe acceleration during jumps.

Both have their own map formats, their own timer servers, their own world-record ladders, and their own community that's been active since ~2001.

Kreedz Climbing (KZ)

Named after Dutch mapper Kreedz, who released the first climbing-focused maps in 2001. KZ maps are timed jump puzzles — complete the course from start button to end zone as fast as possible.

Map prefix: kz_, with variants bkz_ (bonus KZ), xc_ (extreme climb).

Core techniques

  • Long Jump (LJ) — the flagship technique. Crouch, jump, and air-strafe left+right in a rhythmic pattern to fly 250+ units on a single jump.
  • Duck Jump (DJ) — jump then rapidly crouch mid-air to reach ledges you couldn't grab standing.
  • Edge Jump (EJ) — land your feet exactly at a ledge's edge to gain a small altitude bonus on the next jump.
  • Strafe Jump — chain jumps preserving your horizontal speed between them. Chains of 8-15 strafe jumps are a serious skill.
  • Ladder Jump — leap off a ladder with maintained velocity.
  • Bhop drop — chain small bhops on downward slopes to accelerate.

Server tuning

sv_gravity 800
sv_maxvelocity 3500
sv_accelerate 5
sv_airaccelerate 10

Difficulty categories

Servers group maps by difficulty:

  • Easy — first steps, straight LJ challenges. kz_frozen, kz_beginner
  • Medium — combining techniques. kz_arte, kz_climb
  • Hard — precise chains required. kz_kzsca_bhop, kz_megabhop
  • Legendary — pro-only, hours-long records. kz_bhop_extreme, kz_h4v0k_shredda

Pro vs Noob mode

Two run styles:

  • Pro (a.k.a. "no shortcuts") — must complete the intended route, no teleports on falls
  • Noob (a.k.a. "TP") — teleport back to last checkpoint on fall; friendlier for learning

Bunny Hop (Bhop)

Bhop is the discipline of continuous jumping — hitting jump the exact frame you land so your feet never touch the ground for more than one server tick. Every landed jump preserves horizontal velocity; air-strafing between jumps adds more.

Map prefix: bhop_, kz_bhop_ (KZ-style with bhop focus).

Server tuning

sv_airaccelerate 10-100  // varies
sv_maxspeed 320
sv_gravity 800

Some bhop servers uncap sv_maxspeed for insane speeds; the "legit" record scene keeps it at 320.

The +bhop debate

Some players use a script binding jump to the mouse wheel — every scroll produces perfect-tick jumps automatically. This is banned on record servers but common on casual pub bhop.

// Legit binds — jump on scroll (one jump per scroll click)
bind "mwheelup" "+jump"
bind "mwheeldown" "+jump"

// Cheat script — auto-repeating (banned)
alias +bhop "alias _special @bhop;@bhop"
alias -bhop "alias _special"
alias @bhop "+jump;wait;-jump;wait;special"

Timing perfectly with the space bar (called "scrolling with your finger") is the mark of a legit bhop player.

Popular Bhop maps

  • bhop_arcane — the beginner favourite; 3 stages
  • bhop_lego — colourful mid-tier map
  • bhop_gecko — long-runner map with checkpoints
  • bhop_hedge — hedge-maze themed
  • bhop_monster_jam — high-difficulty, non-stop chains

Timer servers and records

Both KZ and Bhop maps host servers with real-time timers:

  • Xtreme-Jumps — xtreme-jumps.eu — the biggest record ladder for KZ, Surf, Bhop and Trikz
  • Kreedz.com — the original community, still active
  • AlliedModders plugins — PlayerJumpstats etc. — server-side timer plugins

Trikz — the team variant

Trikz is team-based KZ where players boost each other over obstacles they couldn't reach alone. One player crouches, another jumps off their head — chain the boosts across 3-4 players to solve movement puzzles.

Map prefix: trikz_. Small dedicated scene, mostly EU-based.

Movement mechanics that matter

  • Ground friction resets speed — touching ground for even 1 tick above the normal move speed cap slows you back down
  • Air acceleration is the whole game — every millisecond airborne is a chance to gain speed
  • Duck timing — crouching in the air alters your hitbox and jump-height calculations

Learning path

  1. Start on easy KZ maps with a checkpoint plugin (kz_beginner)
  2. Move to Bhop with autobhop on beginner maps to feel the strafe rhythm
  3. Turn autobhop OFF and practice legit bhop on bhop_arcane
  4. Progress to medium KZ maps chaining LJs
  5. Attempt WR records on your favourite maps

Prep servers exist in every region. Search "KZ" or "Bhop" in the master server list.
