Half-Life 1 Beta updated

We have released a Beta update for Half-Life and associated games. Changes in this update are:

• Fixed music tracks to correctly play across level change and to not stop (or restart) at unexpected times

• Clamped health values to fix display issues when it dropped below 1 or above 255

• Draw the "Paused" message when you pause the game

• Fixed custom game menus (like ones displayed by AMXModX) not rendering correctly
