Free weekend to Modern Warfare 2.
Modern Warfare 2 is running a free weekend and you can check it out right now at no cost except your time, your bandwidth, and your tolerance for twelve year olds who don’t know how to turn off their microphones. The free weekend runs from March 16 through March 20 and grants access to the following maps/modes:
Core (6v6) Maps: Farm 18, Mercado Las Almas, Shipment, Dome, Himmelmatt Expo (NEW!)
Core Modes: Team Deathmatch, Hardpoint, Domination, Kill Confirmed, Gun Game, Infected, One in the Chamber, All or Nothing
Battle Maps: Santa Seña
Battle Map Modes: Ground War, Invasion
Special Ops: Atomgrad — Special Ops Raid Episode 01 (Standard difficulty only)
Owners of the game will note which modes/maps are unavailable for free players if they wish to avoid the onslaught of burner cheat accounts that will no doubt be used this weekend.
