[PLAYSTATION 2 ] Global Defence Force

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.
