Chain Run

Chain Run, Slash it Open with a Stolen Bike!! (盗んだバイクで斬り開くッ!!「チェン走」Nusunda baiku de kiri hiraku ~tsu! ! `Chen hashi') is an 8-bit style web browser mobile game released on August 3rd, 2023, to commemorate the release of Volume 15 in Japan.

It features unique 8-bit sprite art of both Asa and Denji, with Pochita as the mascot on the website. It was initially released alongside a campaign to win a Chainsaw Man bike figure, depicting the bike that Denji and Asa ride during the Falling Devil Arc.

Gameplay
The aim of the game is to survive as long as possible, while escaping the tentacles chasing you. Said tentacles will multiply the further you progress, increasing difficulty. You may also occasionally encounter the Gun Devil and Darkness Santa Claus as minibosses. On your journey you will also encounter the likes of the Tomato Devil, Chicken Devil, and another unspecified Devil which you can run over to increase your Score. The game does not have an ending and will continue endlessly until the player dies. The game also uses panels from the manga to tell the story, specifically scenes leading up to Denji and Asa's escape via bike.

If the player is killed, the results screen shows a manga panel of Denji lying on the ground defeated, pressing "Try Again" will show a panel of Denji pulling his ripcord to revive.
