Days after Daybreak Games announced that the open beta for H1Z1 on PlayStation 4 crossed one million players, it’s now celebrating another milestone. On May 26th, the studio confirmed that its Battle Royale-style title had seen more than 4.5 million players on PS4.

To thank players, Daybreak has provided Blue Barbed Hellfire 4-6 in players’ inventories. Furthermore, Duos is now available for players with the most recent patch (along with different fixes).

H1Z1 recently left Steam Early Access, having started out as a zombie survival title before being split off into Just Survive and King of the Kill. The latter would be renamed to H1Z1 and launch as a Battle Royale title with the vehicle-heavy mode Auto Royale.

Suffice to say, there wasn’t much enthusiasm on Steam and H1Z1 went free to play shortly after. It did very little to help and the company suffered lay-offs in the meantime. However, it appears that the reception to the PS4 open beta has been strong. Can Daybreak continue with this momentum? We’ll find out in the coming months.

Daybreak Games Company’s off-shoot of H1Z1, namely King of the Kill, will be releasing outside of Steam Early Access on September 20th for PC.

Larry LaPierre, senior VP of games at Daybreak, noted that, “You could make top 60 in one match and top five in the next; the drama of that competition makes King of the Kill extremely entertaining to play and watch.

“The game is inherently competitive, but by design all players have a chance of claiming the coveted number one spot, not just the elite. The feeling you get when you outlast hundreds of other players – it is what drives players to compete – and you can’t get it anywhere else.”

Several improvements and changes have been made in Early Access including a revamped world map in the form of The Arena, a new UI, training mode, improved combat and vehicle systems, Skirmishes and other such changes.

Unfortunately, development is currently “paused” on the Xbox One and PS4 versions of the game. Head to the developer’s official site for more information.
