Infinity Ward creative strategist Robert Bowling has told CVG the studio's working hard to identify and address any Modern Warfare 3 multiplayer exploits before the game launches this November.
He also confirmed reports that the studio has flown in an outside group - which describes itself as "a community of gamers who have become infatuated with discovering and sharing glitches, exploits, tricks, and strategies" - to help test the shooter.
"The mapMonkey's are correct," he said. "They're out at the studio to help us run Modern Warfare 3's multiplayer through its paces.
"While we've been hammering away testing on it since it's been up and running, these guys focus specifically on exploits that can potentially be used to an unfair advantage, such as getting outside a map's playable area, inside geo, or find weapon / equipment exploits that were not intended by the designer so that we can catch and address these before it gets out to the public.
"They're a great addition to an already rigorous QA process that the internal team here at Infinity Ward / Sledgehammer and additionally at Activision have been doing since development began," Bowling added.
Publisher Activision has promised Modern Warfare 3 will deliver "the most advanced multiplayer ever". Little has been revealed so far, but Infinity Ward has confirmed it'll feature a heavily revamped killstreak system. Check out a list of rumoured MW3 killstreaks here.
The beta test for new online service Call of Duty Elite, which will launch fully alongside Modern Warfare 3 later this year, is set to kick off tomorrow using CoD: Black Ops.
