This year we're taking it to the next level with explosive events and activities - including two fully fledged challenge teams who'll be going head-to-head with each other throughout the full 24 hours.
We'll also be hosting some pretty hot live entertainment, including a live fire walk outside of the Jagex offices.
Of course, we'll also be featuring your favourite JMods on our live stream and showcasing some awesome game content.
We'll be reopening the Well of Goodwill[help], too: an in-game feature which allows you to donate in-game wealth and items to raise money for SpecialEffect, with every 5 million you donate converted into US$1, and each Bond you donate converted into US$4.70. All money raised through the well will be sent on directly to charity.
GameBlast is a community event, so we've invited over 30 players to join us at Jagex HQ this year, featuring on the live stream and adding to the great line up we've got planned.
There'll be a brand new item in Solomon's General Store as well – only available to purchase during the upcoming Double XP Weekend. The new outfit - wearable in-game as a cosmetic override - will feature the '24' GameBlast logo, with all proceeds going directly to SpecialEffect.
Last year we raised almost £50,000 for SpecialEffect and this year we're hoping to raise even more. With your help we know it's possible and above is just a teaser of what we've got planned for the night, so stock up on your energy drinks, get your snacks on standby and prepare for an action-packed night of fun, laughs, gasps and mad XP gains.
