Who knew that at age 19, I would be a World Champion PC gamer. When I was 13, I actually

played competitive billiards in professional tournaments and won four or ve games o guys

who played at the highest level. I actually thought of making a career of it, but at that young

age situations change rapidly. Because I’ve been blessed with great hand-eye coordination and

a grasp of mathematics (an important element in video gaming) I gravitated to that activity.

GOING PRO

I started professional gaming in 1999 when I entered the CPL (Cyberathlete Professional

League) tournament in Dallas and won $4,000 for coming in third place. Emerging as one

of the top players in the United States, a company interested in sponsoring me ew me to

Sweden to compete against the top 12 players in the world. I won 18 straight games, lost

none, and took rst place, becoming the number one ranked Quake III player in the world

in the process. Two months later I followed that success by traveling to Dallas and defending

my title as the world’s best Quake III player, winning the $40,000 grand prize. From there

I entered competitions all over the world, including Singapore, Korea, Germany, Australia,

Holland and Brazil in addition to Los Angeles, New York and St. Louis.

WINNING STREAK

I was excited to showcase my true gaming skills when defending my title as CPL

Champion of the year at the CPL Winter 2001 because I would be competing in a totally

dierent rst person shooter (fps) game, Alien vs. Predator II. I won that competition and

walked away with a new car. e next year I won the same title playing Unreal Tournament

2003, becoming the only three-time CPL champion of the year. And I did it playing a

different game each year, something no one else has ever done and a feat of which I am

extremely proud.

At QuakeCon 2002, I faced o against my rival ZeRo4 in one of the most highly

anticipated matches of the year, winning in a 14 to (-1) killer victory. Competing at Quakecon

2004, I became the World’s 1st Doom3 Champion by defeating Daler in a series of very

challenging matches and earning $25,000 for the victory.

Since then Fatal1ty has traveled the globe to compete against the best in the world, winning

prizes and acclaim, including the 2005 CPL World Tour Championship in New York City for

a $150,000 rst place triumph. In August 2007, Johnathan was awarded the rst ever Lifetime

Achievement Award in the four year history of the eSports-Award for “showing exceptional

sportsmanship, taking part in shaping eSports into what it is today and for being the prime

representative of this young sport. He has become the gurehead for eSports worldwide”.

Fatal1ty Story

LIVIN’ LARGE

Since my rst big tournament wins, I have been a “Professional Cyberathlete”, traveling the

world and livin’ large with lots of International media coverage on outlets such as MTV,

ESPN and a 60 Minutes segment on CBS to name only a few. It's unreal - it's crazy. I’m living

a dream by playing video games for a living. I’ve always been athletic and took sports like

hockey and football very seriously, working out and training hard. is discipline helps me

become a better gamer and my drive to be the best has opened the doors necessary to become

a professional.

A DREAM

Now, another dream is being realized – building the ultimate gaming computer, made

up of the best parts under my own brand. Quality hardware makes a huge difference in

competitions…a couple more frames per second and everything gets really nice. It’s all about

getting the computer processing faster and allowing more uid movement around the maps.

My vision for Fatal1ty hardware is to allow gamers to focus on the game without worrying

about their equipment, something I’ve preached since I began competing. I don’t want to

worry about my equipment. I want to be there – over and done with - so I can focus on

the game. I want it to be the fastest and most stable computer equipment on the face of the

planet, so quality is what Fatal1ty Brand products represent.
