This basically means that PC gamers are able to download and play Infinite Warfare – without spending money – until the end of July 30th. Note that you will not be able to add it to your Steam library then play it in the future because after promotion you have to pay for it. In other words, this is a free program to play, not a free product.
In addition to the free promotion, Activision is also offering 50% discount on Call of Duty: Infinite Warfare. Thus, people can buy games with about $29.99.
Another thing to note is that this promotion only allows PC gamers to play Multiplayer mode.
Call of Duty: Infinite Warfare is the first product of Infinity Ward- new developer for the Call of Duty series. The game focuses on the battle for the Solar System against the SDF, who are trying to gain control of the area. The player will play Captain Nick Reyes of Captain Combat Air Recon force (SCAR) and use advanced combat and military combat skills to counter the brutal plans of the SDF.
