Almost exactly a month after Red Dead Redemption 2 launched, developer Rockstar has announced that the game’s online mode will start rolling out this week. The beta for Red Dead Online will actually be available tomorrow for some users, as Rockstar is staggering the launch, likely to avoid the server issues that plagued GTA Online when it debuted several years ago.

Those who purchased the “ultimate edition” of the game will have access to the Red Dead Online beta starting on Tuesday, November 27th, and on Wednesday, it will open up to anyone who played Red Dead Redemption 2 when it launched on October 26th. On Thursday, anyone who played the game between October 26th and 29th can access the beta, and it will finally open up to everyone on Friday, November 30th. The online spinoff is free for anyone who owns the base game on PlayStation 4 and Xbox One.

As for what you’ll actually be doing in Red Dead Online, there’s still a lot we don’t know. Here’s how Rockstar explains it:

With the gameplay of Red Dead Redemption 2 as its foundation, Red Dead Online transforms the vast and deeply detailed landscapes, cities, towns, and habitats of Red Dead Redemption 2 into a new, living online world ready to be shared by multiple players. Create and customize your character, tailor your abilities to suit your play style, and head out into a new frontier full of things to experience. Explore this huge world solo or with friends. Form or join a posse to ride with up to seven players; gather around the fire at your camp; head out hunting or fishing; visit bustling towns; battle enemy gangs and attack their hideouts; hunt for treasure; take on missions and interact with familiar characters from across the five states; or fight against other outlaws in both spontaneous skirmishes and pitched set-piece battles; compete with other players or whole posses in open world challenges and much more.

If GTA Online is any indication, Red Dead Online is a game that will continue to change and expand over time. Despite launching back in 2013, Rockstar continues to update GTA Online with new features and options; the game’s biggest expansion, a sprawling multipart heist, debuted last December.
