Black Mesa: How to Get Bloody Hands/Weapons

Back in the earlier years of Black Mesa, there used to be blood on your hands and weapons when you would kill someone/thing.

This feature was later removed due to performance issues. But there is still a way to enable it. And it’s a lot easier than expected.

To get bloody effects, open up the developer console and write “cl_mdldetailfx_enable 1” (without the quotation marks) and then simply kill something/someone.
