Zombie in Gta:SA

Zombie in Gta:SA is a screamer video uploaded to YouTube in October 2007 by the user Katrousek.

Video
We start with a white screen with black text reading "i see zombie in Gta:SA. No mod no cheat!! Very scary!!" We then cut to gameplay footage from Grand Theft Auto: San Andreas showcasing Carl Johnson in Doherty just outside a construction zone. Carl proceeds to run towards the site until the white screen returns simply stating "WTF???" as if something happened as Carl was running. Carl enters the deserted site and walks up to some large pipes. Briefly, the white screen returns with the question "See him?" We return to the game as Carl takes out his camera and starts filming the inside of one of the pipes to zoom in on the brick wall just outside. Shortly after, a zombie from Half-Life 2 appears with a loud female scream.
