Does MW3 support cross-platform multiplayer

MW3 will again be using Valve's anti-cheat system VAC.

The inclusion of dedicated servers in MW3 should allow for a better implementation than was done for MW2. VAC is designed to use a delayed banning system so that cheaters can't tell which cheat caused them to be banned. Due to this it is expected to be used in addition to server administrators to kick/ban cheating users from their server till that point. I can't seem to find much details on the abilities of server admins or if kick voting will be available though.

It won't require any additional middleware software except for Steam which is required to run the game.

VAC itself doesn't have an official publicly searchable database but using the Steam Community you can see the VAC status of anyone with a public profile. I you want a searchable list of banned players you can use VAC Banned its an unofficial database of people who have been banned by VAC.

I only have access to the Xbox 360 version of the game but here are some of the options that you can set up.

• Pick any of the maps
• The standard game types of: FFA, TDM, S&D, sabotage, domination, headquarters, CTF, demolition, kill confirmed, and team defender
• And alternate modes of: drop zone, team juggernaut, juggernaut, gun game, infection, and one in the chamber
• Enable custom game options such as number of lives, create customized default classes, turn off the kill cam, turn off killstreaks, etc.
• You can create custom default classes and assign them to each team.
• You can also allow custom classes, but restrict choices. This means you can turn off individual guns, entire gun classes (assault, smg, lmg, etc), turn off perks, etc.

Yes, MW3 will support LAN play.

Infinity Ward creative strategist, Robert Bowling has been answering questions on Twitter in the aftermath of the Call of Duty XP event that happened over the course of the weekend. Dedicated Servers for Modern Warfare 3 have already been confirmed, but Bowling also mentions that LAN play will be possible, which certainly wasn’t a given, considering how Modern Warfare 3 will tie in heavily with Activision’s online Call of Duty Elite service.

“Yes, #MW3 has LAN,” Bowling tweets, “along with detailed class restriction control + default class creation option.”

The class restriction control will give LAN gamers the ability to “restrict any weapon, equipment, perk, deathstreak, secondary, attachment, ANYTHING from being used when setting up game,” Bowling adds.
