Blizzard has announced a Collector's Edition of its upcoming Diablo 3 expansion Reaper of Souls , which will bundle a box-load of extra content to series fans willing to part with a little extra cash over the standard version of the game.

For your £65, you'll get a physical copy of the game for PC or Mac, a Behind the Scenes Blu-ray/DVD two-disc set with interviews, discussions and commentary from the developers, a CD soundtrack, a hardback art book and a mouse mat featuring the game's main antagonist Malthael, the Angel of Death.

You'll also get access to some exclusive in-game content for Blizzard's most popular games. For Diablo 3, this includes three unique helmets, a selection of weapons and a spectral hellhound minion to accompany you through Sanctuary. World of Warcraft players will gain access to a Treasure goblin pet, while StarCraft 2 gamers can pick from several new Crusader-inspired portraits and Malthael decals.

Reaper of Souls is the first major expansion to Diablo 3, which increases the level cap to 70, adds a tough new fifth act along with new skills, runes, and passive abilities for all characters. A new Crusader character class, which specialises in defensive play, new weapon types including flails and larger spears, and holy magic will also be added.

If you want to secure a copy of the £65 Collector's Edition, Amazon has it available for pre-order now. The game itself doesn't launch until the 25th of March, so you still have time to level up those Diablo 3 characters before the new expansion arrives.
