Monster Attack

Monster Attack is a third-person action shooter and the first game in the Chikyuu Boueigun / Earth Defense Force series.

The player takes the role of an EDF (Earth Defence Force) infantry man to single handily battle hordes of giant bugs, robots and alien ships that have invaded Earth, across 30 missions.

The PlayStation 2 (2000) is the best-selling game console in history, with a library exceeding 9,000 titles that spans everything from budget shovelware to genre-defining classics. That massive volume means PS2 collecting is accessible and affordable overall, but a handful of low-print-run RPGs and cult titles have become genuinely expensive — a common pattern once a console's original audience grows up with disposable income.

Gamevaro tracks Monster Attack for PlayStation 2 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 Monster Attack 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 PS2 release dates back to 2004.

Market insights

Monster Attack has a steady sales history on the tracked marketplaces, meaning enough copies circulate to establish a reliable market price.

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.
