The free week for Call of Duty 21 has arrived! From December 14th to 20th, players can dive into the multiplayer and zombies modes of Call of Duty 21: Black Ops Cold War. This is a great opportunity to try before you buy.  This guide provides a step-by-step tutorial on downloading the game via Steam and setting up your Activision account for a smooth gaming experience.

First, you'll need to search for the game on Steam. However, due to server load, directly accessing the Steam store might be challenging.

We recommend using Lagofast game booster to search for Call of Duty and optimize your network connection. This will also optimize Steam's network, ensuring faster downloads and reduced in-game latency for a better gaming experience.
