The GOLDSOURCE engine shouldn’t be able to do this! This mod is literally SORCERY. ▸ Download Diffusion for FREE: https://www.moddb.com/mods/diffusion/downloads/diffusion ▸ Watch the Half-Life Diffusion playlist: https://www.youtube.com/playlist?list=PLAnfG6CHIYjwWqs1c6yJ70koiEdTw4Gno So, I finally jumped into Half-Life: Diffusion and man, my brain is actually melting. The game looks way too good for something built in GoldSource; the lighting is literally magic. We start this let’s play as some dude named James Smith whose car dies in the middle of a Utah desert, which is basically my worst nightmare. Once I stop trying to lick the high-voltage signs, I make it into this secret base. The gameplay gets wild fast because I have to put on this prototype Diffusion Suit that basically keeps shocking me while I explore. This walkthrough takes us deep into the labs where everything goes south, and suddenly I’m doing a stealth playthrough using nothing but a knife against scary HECU soldiers. It’s a total mess in the best way possible. This whole playthrough is just me wondering how a game engine from the 90s can be tinkered with to look better than my actual life. ▸ Gotta join that Patreon: https://www.patreon.com/rockyrockheadgaming ▸ Do the Discord: https://discord.com/invite/QBtteqzsK8 ▸ See me LIVE on Twitch: https://www.twitch.tv/rockyrockhead ▸ Use my EPIC Creator Code: ROCKHEAD #firstplaythrough #gamingcalamity #letsplay #rockyrockhead
