Carriers is a multiplayer Half-Life 2 mod being created by the Shellshock Gaming development team. It's based around a modern-day zombie apocalypse, where players must work together to survive. But now the luck of the carriers has run out, and their immune systems are failing.
Why does that picture look familiar? I feel like I've seen it before, but I don't know why.
Because it's so similar to the other screenshot about "Matthew"?
Reminds me of the ones in Silent Hill, aha.
