This leads into mass fighting and mayhem, and it is up to Grim, Billy, Mandy, and Irwin to figure out who unleashed the balls.
Each character has special abilities and moves, as well as weapons to utilize.
Each character also has a Mojo meter, which is a power bar.
If filled once, it can be used to deal heavy damage, and if filled twice, it can be used to knock out all players.
The game spans across several levels that are destructible and feature roughly most of the major characters from Grim Adventures, and have various single-player and multiplayer modes.
About Game Boy Advance
Nintendo's Game Boy Advance (2001) offered near-SNES-level graphics in a handheld and became a home for excellent ports as well as original titles across nearly every genre. GBA cartridges are generally durable and plentiful, making it an approachable platform for new collectors, though a few late-release RPGs and limited exclusives have become genuine chase items.
Gamevaro tracks Grim Adventures of Billy & Mandy for Game Boy Advance with separate market values for loose, complete-in-box (CIB) and factory-sealed copies, sourced from real eBay sales. Prices also vary by region — PAL, NTSC-U and NTSC-J releases of the same game often sell for different amounts due to print run sizes and regional collector demand.
