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.
Old graffiti will be found in safehouses, and some will be games, such as naughts and crosses, and possibly hangman.
Some dude:"Stop winning!"
Me:"Nou! >:|"
You've gotta have a sense of humour in the middle of an apocalypse.
