Fatal1ty Story
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
dierent 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”.
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.

In order to avoid damage from static electricity to the motherboard’s components,
•
NEVER place your motherboard directly on a carpet. Also remember to use a grounded
wrist strap or touch a safety grounded object before you handle the components.
Hold components by the edges and do not touch the ICs.
•
Whenever you uninstall any components, place them on a grounded anti-static pad or
•
in the bag that comes with the components.
When placing screws to secure the motherboard to the chassis, please do not over-
•
tighten the screws! Doing so may damage the motherboard.
