During the development of Shaft (a Half-Life beta mod) I messed around making posters in SFM. These are from 2015 and 2016.
🗺️ Half-Life Warp Guide 🗺️ When you reach office complex, make your way up to the second floor and go into the first room on the left. You'll find a TV, and 2 scientists climbing into a vent. Look at the TV, and continue to stare at it for ~12 hours. The screen should fade out and you'll warp to Surface Tension! DO NOT BREAK THE TV!

Started work on a new Half-Life mod! I'm not sure what type of mod it is or what it's even about, but I hope to figure that out one day soon!
