Diablo 3 is getting a nice packaged release on the Blizzard store with the release of the Diablo 3 Battle Chest. It includes Diablo 3 and the Reaper of Souls expansion pack and it costs only $29.99 for the PC. If you don’t already own the game and its expansion, this is a pretty good deal. It’s also set for release in retail stores, if you prefer not to wait for shipping.
If you’re playing it on the PS4 or Xbox One, then you already own the Ultimate Evil Edition, which is basically the same thing.
The new Battle Chest includes all the updates for the game, so you can get started right away without having to update.
The Battle Chest should have you ready to go for the Necromancer class, which comes out next year. It should also prepare you for the release of the Diablo remake in Diablo 3, which is going to be an annual event starting this January called the Darkening of Tristram. You can read up more on the Necromancer here.
