Explosive hotel! (Half-Life 2 and Undertale)

Since I found out that you could put things from the Steam Workshop of Garry's Mod (And any other game with Motor Source) Half-Life, I decided to do a test to see if the game supported it. It's not a big deal but for sure I'm the first to do it in Half-Life 2, this is not done in Garry's Mod. (The video may contain audio de-chronisation due to the way I have to record it)
