When Modern Warfare 3 launches this fall, you'll have had some glitchers
help in making the multiplayer the best it can be. As it turns out,
Infinity Ward has employed the help of those that best break the games
to make the multiplayer as glitch and exploit free as possible. As
detailed in a post on a popular game glitches forum, Infinity Ward has
employed the services of 4 exploit finders to go over their maps with a
fine tooth comb to nip anything that might cause the game trouble down
the line.
Map Monkeys are assisting Infinity Ward on the project, but according to
one of their members, this isn't their first time helping out the
developer. Members of the site were also flown in to help with Call of
Duty: World at War and Call of Duty: Modern Warfare 2. In the case of
Modern Warfare 2, the game had some pretty considerable bugs in the
multiplayer, so it's really unclear if having these guys come on to help
will make Modern Warfare 3 any better at launch.
