How To Change the Gravity on Your Left 4 Dead 2 Server

Important!

Changing the gravity doesn’t just affect player movement! It completely alters the physics of the entire world. Thrown Pipe Bombs and Molotovs will fly massively further, Hunters can pounce straight over skyscrapers, and dead zombies will float away when shot with high-powered weapons. Because Valve protects this physics command, you must have SourceMod installed to force the change.

1. Log In to Your Panel

2. Stop Your Server

3. Select the ‘Files’ Tab

L4D2 Server Dashboard, Files Tab Highlighted

4. Select the ‘left4dead2’ Folder

Navigating to the left4dead2 root folder in the Cybrancee server file manager

5. Select the ‘cfg’ Folder

Clicking the server.cfg file in the Cybrancee file manager to edit configuration settings

6. Select the ‘server.cfg‘ File

Clicking the server.cfg file in the Cybrancee file manager to edit configuration settings

7. Add the Gravity Command

Scroll to the bottom of the document on a new, empty line, and type the following command (we are using 200 as our low-gravity example):

sv_gravity 200

Adding the sm_cvar sv_gravity 200 command to the server.cfg

8. Customise Your Gravity Level

You can change the number 200 to whatever gravity level you want.

800 is the normal, default game gravity.

400 allows for big, floaty jumps but still keeps the game easily playable.

150 or 200 is full-blown moon gravity.

1200 makes players extremely heavy and reduces jump height.
