CS 1.6 Fall Damage Not Working: Causes and Server Fix

Last updated: May 7, 2026

CS 1.6 fall damage not working is almost always intentional – either the server is running a no-fall-damage AMXX plugin, sv_gravity is set low enough that falls are survivable, or you are playing on a game mode (surf, bhop, deathrun) where fall damage is disabled by design. As a regular player you cannot enable fall damage yourself – it is server-controlled. Below is a full explanation of how fall damage works in CS 1.6, how servers disable it, and how to fix it if you are a server admin. If your installation is corrupted, download Counter-Strike 1.6 first.

CS 1.6 Fall Damage Mechanics Explained

CS 1.6 runs on the GoldSrc engine where fall damage is calculated based on fall velocity at the moment of landing. There is no mp_falldamage cvar in CS 1.6 – that command only exists in Source engine games (CS:GO, Half-Life 2). Fall damage in CS 1.6 is controlled differently:

Fall Height	Approximate Damage	Notes
Short fall (1-2 player heights)	0 damage	Safe – no damage below a certain velocity threshold
Medium fall (3-4 player heights)	5-20 damage	Survives with full health, audible landing sound
Large fall (5-6 player heights)	30-60 damage	Significant damage – can be fatal at low health
Very large fall	100+ damage	Lethal – instant kill at most heights above de_nuke catwalk equivalent

Fall damage scales with sv_gravity – lower gravity means lower fall velocity, which means less or no fall damage. Standard gravity is 800.

Counter-Strike 1.6 Fall Damage Disabled – Common Reasons

Reason	Who Controls It	Can Player Fix?
AMXX no-fall-damage plugin active	Server admin	No – server-side only
sv_gravity set very low (under 200)	Server admin	No – server-side only
Surf or bhop server mode	Server admin	No – intentional game mode design
Deathrun server	Server admin	No – intentional
Player used fall cancel technique	Player skill	This is intentional game mechanic

As a regular player – if fall damage is not working on a server, it is because the server disabled it. There is nothing to fix on your side. Join a standard public server (de_dust2, de_inferno etc.) for normal fall damage behavior.

sv_gravity – How It Controls Counter-Strike 1.6 Fall Damage

sv_gravity controls the strength of gravity on the server. Standard CS 1.6 gravity is 800. Changing it directly affects fall damage:

sv_gravity Value	Effect on Fall Damage	Common Use
800 (default)	Normal fall damage	Standard CS 1.6 servers
400-600	Reduced fall damage – falls from moderate heights safe	Some zombie and fun servers
100-200	Very low fall damage – most falls survivable	Surf and bhop servers
50 or below	Effectively no fall damage	Deathrun and jump servers

Check the current gravity on a server:

sv_gravity

If it returns a low value – that is why fall damage is absent or reduced.

CS 1.6 No Fall Damage AMXX Plugin

The most common way servers disable fall damage is through an AMXX plugin. Popular plugins used:

• No Fall Damage by Subb98 – available on GitHub and AlliedModders. Hooks into the fall damage calculation and sets it to 0 regardless of fall height.
• Fall Damage Editor – available on GameBanana. Allows custom fall damage multipliers rather than a complete disable.

To check if your server is running a no-fall-damage plugin:

amx_plugins

Look for any plugin with “fall” or “damage” in the name.

Enable Fall Damage in Counter-Strike 1.6 – Server Admin Fix

If you are the server admin and want to restore normal fall damage:

Check and fix gravity

sv_gravity 800

Add to server.cfg to make it permanent. This alone restores standard fall damage if no plugin is overriding it.

Disable no-fall-damage plugin

1. Open cstrike/addons/amxmodx/configs/plugins.ini.
2. Find the no-fall-damage plugin entry.
3. Add ; at the start of the line to disable it:

   ; nofalldamage.amxx

4. Restart the server or type amx_reloadadmins in console.

Add fall damage plugin with custom values

If you want fall damage but with reduced values (e.g. for a fun server), use the Fall Damage Editor plugin from GameBanana instead of completely disabling protection.

CS 1.6 Fall Damage Cancel – Crouch Landing Mechanic

CS 1.6 has a built-in fall damage reduction mechanic – crouching just before landing reduces or eliminates fall damage. This is intentional game design, not a bug:

• Hold CTRL (crouch) just before landing – timing must be within the last fraction of a second of the fall
• Landing in a corner where three surfaces meet (two walls and a floor) sometimes cancels fall damage due to collision normal averaging
• Both techniques also suppress the landing sound – useful for stealth approaches

If you are seeing no fall damage because a teammate or enemy is using this technique – it is a legitimate skill-based game mechanic.

Quick Reference

Situation	Cause	Fix
No fall damage on all servers	Not possible as a client-side issue – check which server you are on	Join standard public server
No fall damage on specific server	Server has no-fall-damage plugin or low sv_gravity	Check sv_gravity in console, check amx_plugins
Fall damage reduced but not zero	sv_gravity below 800 or damage multiplier plugin	Server admin: set sv_gravity 800
Server admin: want to enable fall damage	Plugin or gravity disabled it	sv_gravity 800 in server.cfg, disable AMXX plugin
Player canceling fall damage by crouching	Intentional game mechanic	Not a bug – this is how CS 1.6 works
mp_falldamage command not found	That cvar does not exist in CS 1.6 – it is Source engine only	Use sv_gravity instead
