RuneScape’s notorious Anti-Santa is back and plotting another war on Christmas festivities. It’s up to players to infiltrate his camp in a new seasonal quest and put an end to whatever he’s planning.
This is but the start of RuneScape’s Christmas 2015, which will run all month long. The event includes a multi-stage quest, daily advent gifts, Winter Weekends, and other fun activities.
The questline, titled The Pinch Who Stole Christmas, will play out over the course of four weeks as players investigate some mysterious disappearances. By completing each stage, players will unlock cosmetic rewards (such as a new snowboard design) and gain access to a cook-off event.
