With this, you can upgrade Half-Life versions and even downgrade it. You can only use this in the WON version.
This is a a official update or used to downgrade for Half-Life! If you have older versions of Half-Life won, ex: 220.127.116.11, Use this to upgrade. If you have newer versions, you can downgrade it with this as well. This is useful if you need to use Xash3D as it needs version 18.104.22.168.
Remember! This does not work on Steam. Only in the CD WON.
If you have Opposing Force installed, this will upgrade it to version 22.214.171.124 as well.
