So yeah, just so you guys know we're working on the mod. THIS IS A GORE DEMO, NOT THE FULL SCIENTIST SLAUGHTERHOUSE 2! Instructions. Open using 7Zip (or any program that supporst 7z) and place the folder in your Half-Life folder, in Steam/steamapps/common. Restart steam and you'll have a mod called "TestModBlood" on your games list. Tell me if something works wrongly or anything.
