A Call of Duty: Modern Warefare 3 Steam Free Weekend starts on Thursday, April 26th at 10am Pacific Time. You can start pre-loading the game now.
You’ll be able to play the multiplayer portion of the game all you want for free until Sunday.
Usually these are accompanied with a sale on the game. I’m going to guess at least 33% off. This is a good chance to try the game out.
This game has a 78 metascore.
