It seems like Epic Games’ Fortnite is finally making its public debut in a playable alpha.

Beginning today, the new playable alpha for the survival shooter of sorts is going to run until December 19th. Featured above, you can view a brand new trailer for the game.

The invite-only alpha is going to ensure that all of the core elements of the game are working. Epic has warned their fans that Fortnite, in its current form, is still “rough around the edges,” but this early look will help their development.

You should make sure to check your inbox to see if you’ve gotten an invite, and if you haven’t registered yet, you still can via the official Fortnite website.
