CS 1.6 plugin stack: install the correct framework

SHORT ANSWER

Counter-Strike 1.6 uses Metamod and AMX Mod X for the supported community-plugin workflow covered here. Install only current upstream packages for GoldSrc, verify the framework before adding a plugin, and keep the stock server snapshot available.

Before you change anything

1. A legitimate Steam installation or dedicated-server installation for Counter-Strike 1.6.
2. A backup of every file that will be changed.
3. Access to the local client console or the dedicated-server console, as appropriate.

Version-specific procedure

1. Confirm that the stock dedicated server starts and accepts a connection.
2. Download Metamod and AMX Mod X only from the linked upstream project pages.
3. Follow the upstream layout for the cstrike game directory; do not improvise a loader path from another engine.
4. Restart the server and verify the framework before installing any third-party plugin.
5. Capture `meta list` and `amxx plugins` in the server console; add one plugin only after the framework baseline passes.

Verify the result

1. The framework reports its version in the server console.
2. The stock server still loads a stock map with the framework and no optional plugin.

Rollback

1. Stop the server and restore the pre-framework game-directory snapshot; never delete individual loader files while the process is running.

Common pitfalls

1. A plugin’s marketing claim is not compatibility evidence; require a current release and engine/build support statement.
