During today’s Alcatraz map announcement, Treyarch snuck in a little bonus at the end of the trailer. Blackout will be free all players from April 2nd through April 30th.

The image specified that online subscriptions like Xbox Live and Playstation Plus will be required to play online.

If you’ve been interested in checking out Black Ops 4’s battle royale mode but haven’t yet purchased this game, this is a great time to check it out.

Starting April 2nd until the end of the month, all PC, Xbox One, and PS4 players will have free access to Blackout, while PC and Xbox One players will have to wait a week to jump into Alcatraz.

This isn’t the first time Blackout has gone free to play either. Back in January, Treyarch held a similar event for a week. This marks longest period Blackout will be free for.
