Valve's Team Fortress 2 is about to be invaded by Mabinogi gold, the upcoming MMO from Trion Worlds. Both companies announced today that Steam customers who pre-order Mabinogi by March 4th will receive two exclusive melee weapons in Team Fortress 2: the "Sharpened Volcano Fragment" and "Sun-on-a-stick." Additionally, the Valve team is adding a permanent Team Fortress 2 achievement that grants players a redeemable code for an equally exclusive (and terrifying) headpiece in Mabinogi, the "Well Spun Hat."Team Fortress 2 players will automatically receive the melee weapons beginning today, while players lusting after the Well Spun Hat must complete the new "Mabinogiwalker" achievement. After applying the code on their Trion account page, Mabinogi players will receive the hat in their in-game mailbox beginning with the game's headstart period on February 24th.All Steam pre-order customers will receive the weapons, including those who've already purchased Mabinogi through the digital platform. This offer is available to Steam users worldwide.
