We recently heard HTC is bringing the Half-Life franchise to virtual reality headset Vive , and now you can play the Valve’s classic shooter on smartwatches thanks to a tutorial by modder Dave Bennett.

According to the tutorial, the game is running on an Android-powered LG G Watch using the SDLash app that emulates the GoldSource engine. Bennett notes that the exercise is a proof of concept and is far ideal control-wise. Performance was better than expected, hitting a high of 30 frames per second down to a low of 2FPS.

“Of course, things such as the lava graphics and special lighting caused a huge drop in fps,” Bennett writes. “Also, trying to play a game on Android wear is a nightmare within itself. The app offers touchscreen controls, but on a 1.65 inch screen, they are almost impossible to use. Also, swiping to the left causes the screen to go back to the previous window. “
