It's become more and more common for publishers to have free trial weekends for their games these days, which are mostly for multiplayer modes.
Activision and Infinity Ward have departed from this trend, however, and have announced that Call of Duty: Infinite Warfare is getting a free trial on PlayStation 4 and Xbox One this weekend. You'll have the chance to play the first two levels of the campaign, "Rising Threat" and "Black Sky," multiplayer with a level cap of 15, and Zombies in Spaceland with a level cap of 3.
All you have to do is download the "Call of Duty: Infinite Warfare Free Trial" on December 15. Your progress and experience will carry over if you decide to upgrade to the full game too, and you won't even have to download the entire game if you don't want to. The downside to this is that the trial version weighs in at 60 GB.
The trial ends on December 20, so you have plenty of time to see if it's worth a purchase or not. Do you like the inclusion of zombies and campaign as well?
