Jagex announces 10-player raids are coming to RuneScape, their venerable MMORPG. Participation requires being a premium RuneScape member, and while there are no level requirements, they recommend this for participants at high combat levels with top-end gear. Here's more:

The first of RuneScape's Raids – The Liberation of Mazcab – is now yours to conquer.

To start, join a group of up to 10 players in the Grouping System, and select 'The Liberation of Mazcab'. Then, head north to the magical barrier between the two goebies, and enter to get started.

You'll venture through an instanced area, using your teamwork and combat skill to make it to two bosses: the cruel Beastmaster Durzag and the mighty water elemental Yakamaru. Even reaching them will take teamwork and skill, and it'll take everything you've got to defeat them.

There are also Raid Feats – special acts of daring for the bravest and craziest raiders to aspire to. There are five per boss, and completing all of them unlocks the Daredevil title.

These are some of the most challenging encounters ever seen in RuneScape, so you're on your own from here. We're really excited to see you get to grips with them.
