Following first word of a crossover back in July, the popular manga and anime series "Attack on Titan" has expanded into Ethereum metaverse gaming platform The Sandbox with a new game called Attack on Titan: Invasion.

Attack on Titan: Invasion lets players become soldiers defending the Trost District against Titan attacks, working alongside characters like Eren Yeager, Mikasa Ackerman, and Armin Arlert from the source material. Players must complete training and successfully resist multiple invasion cycles to reach the final quest with Eren.

Playable on Windows and Mac, The Sandbox’s latest addition challenges participants to protect humanity by defeating waves of Titans. The success of the invasion depends entirely on players' combat abilities and strategic decision-making.

The Sandbox, which recently began its Alpha Season 4, continues to expand its portfolio of branded experiences with the latest offering. Over the years, The Sandbox has teamed with an array of brands and celebrities, including Snoop Dogg, The Smurfs, Paris Hilton, Warner Music Group, Tony Hawk, and beyond.

Attack on Titan NFT avatars for The Sandbox went on sale last week, selling for 120 SAND—almost $75 worth at the current price of the game’s token. The Attack on Titan: Invasion experience is free for anyone to play, even without an NFT avatar.
