About this game
The second game in the The Chikyuu Boueigun series , renamed Global Defence Force for its English release (similarly the first game was renamed Monster Attack for its English release).
It's been two years since the invading alien menace was defeated by the Global Defence Force (the game renames the "Earth Defence Force" from the previous game), but like any good off-world threat, they're back for more, and they've brought new weapons and technology in their attempts to take Earth and eliminate humanity.

Thankfully, the GDF has also been developing new technology to fight them.
Global Defence Force is a third-person action shooter.
Choose from either an GDF infantryman or the flight-capable Pale Wing, each with different abilities and dozens of weapons each, and set out to shoot down hordes of giant insects, enormous robots, and UFOs of incredible scale.

But leaving at that would undersell the game; there are numerous new alien types, weapons and environments that add much more variety to things.
The maps are larger and more detailed and missions are longer and much more scripted (where as the original game nearly always threw you into an environment against some preplaced bug's, this time you often have some simple objective(s)) to add further variety.
Finally the physics have been notably enhanced.
Like Monster Attack, the player in Global Defence Force fights completely by themselves despite being part of an army (unless playing offline only 2 player split screen); the ori
About PlayStation 2
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 Global Defence Force Tactics 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 Global Defence Force Tactics 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 2007.
