: It replaces your default spacebar bind with a script that triggers the +jump and -jump commands rapidly.

: In competitive Versus matches, autobhop is widely considered cheating . It provides an unfair advantage, such as allowing a Tank to move faster than Survivors or making a Boomer nearly impossible to hit.
Bunny hopping is a source engine mechanic where a player jumps immediately upon landing while strafing in mid-air. When done correctly, it bypasses the game’s natural speed limits, allowing you to move significantly faster than standard running speed.
When your character stands on the ground, the game applies friction, slowing you down to standard running speed. : It replaces your default spacebar bind with
: Some versions, like the Auto Bunnyhop script on Steam Workshop , include a "method 2" (!bhop2) that removes the shaky camera effect typical of manual hopping.
: Allows players to bunny hop continuously simply by holding the Spacebar or using the +jump command.
Never run a .exe file to gain a movement advantage. Safe configurations use native engine files ( .cfg ) or plain text macro scripts ( .ahk ). Step 2: Test on Local Servers First | | Speed drops after 2 jumps |
For those hosting their own servers or playing locally, server-side plugins provide the most stable experience. AlliedModders Plugin : A standard Sourcemod plugin that provides a command for all players on the server. AlliedModders GitHub Plugin : A "plugin-style" script that can be loaded with the launch parameter for local play. Important Considerations : While standard console scripts (
For those running their own servers, a GitHub-based plugin is considered a verified approach.
In the L4D2 community, "verified" typically refers to scripts or plugins that are widely recognized as safe, functional, and non-malicious. These methods generally fall into three categories:
The L4D2 community is split. Here is the consensus:
