Choose a Bloons TD 6 hero at any Site of Grace and fight through the Lands Between as them.
Play Elden Ring as a Bloons TD 6 hero.
Rest at any Site of Grace and press H (keyboard) or R3 (controller) to open Monkey Heroes: the Bloons TD 6 roster with their real portraits, read from your own copy of Bloons TD 6.
Playable now: Quincy, Gwendolin and Obyn Greenfoot. The rest of the roster is listed as coming soon.
What you need: Elden Ring (1.17.1) and Bloons TD 6 installed. Melty does the rest. The first Play prepares the heroes from your two games (about two minutes).
Safe for your account and saves: it's single player and offline, with Easy Anti-Cheat off. The mod plays on its own save (copied from yours the first time), so your normal save is never touched. Starting Elden Ring from Steam gives you the normal online game. No game files are included: everything from Elden Ring and Bloons TD 6 is read from your own installs.
