Is there a playable version of the Half-Life 2 Beta?

Is there a remake I can play, or an official build?

The official build exists and is called Mega Build, there are also a number of beta builds and mods for the release. Namely: Coterminus with all additional modifications, Missing information global pack and Half-life 2 2002 edition

Yeah ofc, you can download the Beta on this site on the Downloads page, but i hihgly recommend the Mega Build as it fixes a lot of stuff that was initially broken in the leak...
