MW4 Beta

That’s right: the Call of Duty: Modern Warfare 4 beta will include every mode for players to test. However, we should mention that you won’t be able to play the entire Campaign, but rather a single mission: Entrenched.

The fight is everywhere. Take a first look at "Entrenched" from the #MW4 Campaign.

There will also be two beta waves that players can get their hands on. An Early Access Beta, which will run from August 21st to the 25th, for those who pre-order. Then, a few days later, the Open Beta will run from August 18th to September 1st.

Each beta will include Warzone, Multiplayer, and one Campaign mission. Some multiplayer maps will include Rooftops, Silkworm, Transit 213, Cachette, Lotus, and Kill Block, with more opening up during the Open Beta.

Game modes like team deathmatch, domination, hardpoint, kill confirmed, inflation, and search and destroy will also be available during both beta weekends.
