Comme le dit NoFrag, PunkBuster, le logiciel anti-triche, devrait arriver dans une mise à jour de Call of Duty. Il faut dire que niveau sécurité, Call of Duty s'apparente beaucoup à Valve.

We know concerns about cheating are a big issue in the fan community right now, so we wanted to pass along the following update: Infinity Ward has signed a deal with Even Balance to include PunkBuster for Call of Duty. As more information, including timing, develops on releasing PB support for Call of Duty, we'll let you know. Thanks!
