Valve's classic first-person-shooter Half-Life is, unbelievably, playable on Android Wear.
The game is played using on-screen virtual buttons, but the tiny 1.65-inch screen does make it difficult to control.
All it takes is little tweaking under the bonnet with the SDLash app, which emulates Half-Life's original engine, Goldsource.
Performance is variable, however, with the frame rate ranging between 2 and 30 FPS on an LG G Watch, according to YouTuber Dave Bennett.
For now, this seems to be the only solution to the everlasting problem that is the lack of portable original Half-Life.
