S3kshun8 is the elite hacker who is an old friend of Tyson Rios. He speaks entirely in the 1337 (LEET) speak language and his voice is never heard in the game. He helps both characters in their missions by sending messages to them. During the course of the game, S3kshun8 hacks keypads, helps them by hacking databases and helps co-ordinates. He is mentioned by Brian Hicks, an SSC contractor, that "everybody knows S3kshun8".
