Activision and Sony have partnered up to offer a free trial of Call of Duty Infinite Warfare to all PS4 owners. Starting December 15th, PS4 owners will be able to download a free trial of the game (which includes multiplayer) and play until December 20th.
The Infinite Warfare free trial includes the first two levels of the game’s singleplayer campaign, and full access to the multiplayer portion. Although multiplayer is capped at level 15.
If you decide to purchase the game after the trial ends, your progress will carry over to the full game.
Keep in mind that this is the full game, but with restricted access. Meaning you have to download the entire 60 GB game.
