About Half-Life
Half-Life running on the Xash3D engine in the browser. Back to Black Mesa.
The launcher offers Half-Life and Opposing Force, in English and Russian builds of roughly 214 to 304 MB each, or a ZIP from your own disk. The labels warn that the menu lags and that Opposing Force is an older, buggy build.
