There have been infinite amounts of Half Life 2 mods over the years, but I just recently saw this one and thought it worth sharing. It’s level 1-1 from Super Mario Bros. (or something close to it), rendered in Half-Life format with Headcrabs standing in for Goombas.
I’m working my way through Half Life 2 for the first time on Steam right now, and I have to say there are few things more annoying on earth than headcrabs. Though I guess they’re not really from earth are they? Are they? I find the plot somewhat hard to follow most of the time. All I know is that Halo’s Flood totally ripped them off.
