While attending their school's science fair, they accidentally unleash an ancient and evil demon by the name of Moloch who threatens to bring an end to their world.

The player can switch between either D.J. or Pandora, using a plethora of creative weapons like C-4 hamsters, firearms which range from pistols to shotguns as well as D.J.'s trusty scythe to decimate the enemies.

The gameplay consists of using both the stylus to perform touch-screen gestures and pressing regular pad buttons to create a variety of attacks.

There is also multiplayer with two mini-games that can be played between friends.

One of which is Reaper Ricochet where players bounce C-4 hamsters off of tombstones at each other and the other is War Mode where two teams can engage each other in side-scrolling shoot-em up's.

About Nintendo DS

The dual-screen, touch-enabled Nintendo DS (2004) became the best-selling handheld of all time, helped by its huge and genre-diverse library. Cartridge-based DS games have held up well physically over 20 years, and complete-in-box copies of the system's biggest sellers (Nintendogs, Pokémon, Mario Kart) remain very accessible for new collectors starting out.

Gamevaro tracks Death Jr. and the Science Fair of Doom for Nintendo DS 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.

Adding Death Jr. and the Science Fair of Doom to a Gamevaro collection takes seconds — search by title or scan the box barcode, and the app fills in cover art, release details and current pricing automatically. This NDS release dates back to 2007.

Rarity & condition

Only a handful of market sales have been tracked for Death Jr. and the Science Fair of Doom, suggesting it doesn't trade hands very often — a sign of relative scarcity compared to more common Nintendo DS titles.

Complete-in-box (CIB) copies typically command a premium over loose cartridges/discs because the original box and manual are more fragile and get discarded or damaged over time — fewer complete sets survive.
