Earth Defense Force 2: Invaders From Planet Space

Earth Defense Force 2: Invaders From Planet Space is a port / remake of Global Defence Force. It was released by XSEED Games, Marvelous USA, Inc., and D3 Publisher in North America on December 8th, 2015 for the PlayStation Vita on the same day as Earth Defense Force 4.1: The Shadow of New Despair. It cost $29.99 at release.

Strictly speaking the game is a port of Global Defence Force Portable rather than the original game. Portable (which certainly seems an appropriate title) was a Japan-only PSP version which included additional weapons for the two classes and seven new levels (for a total of 78), all of which are present and correct in IfPS.

The game follows the tactic of Earth Defense Force 2017 Portable of reworking the original title in such a way as to introduce an additional class - in this case, the Air Raider seen in Earth Defense Force 2025 - bringing the total number of playable classes to 3. The IfPS Air Raider is a cut-down version of the class without the ability to summon vehicles and with different strike options, hence his having a separate page to the 2025 class; the Impulse mines and C Bombs are also given back to the Infantry class. The giant insects are officially referred to as "Buggernauts" as opposed to "Gigantors" in the original translation. It also officially dates EDF 2 to take place in 2019, two years after Monster Attack or Earth Defense Force 2017, and 6 years before Earth Defense Force 2025 or The Shadow of New Despair, though since 2025 is also a remake of Global Defence Force and does not acknowledge anything happening in 2019, it does not fit into the same continuity.

It also features a multiplayer mode and a new English dub (the EU release of Global Defence Force had no speech). It is rated T for animated blood, mild language, and violence.

Storyline
This information is copied verbatim from the official site for the sake of posterity.

Dateline: 2017
The alien invasion struck without warning. Enormous insectoid creatures known as “Buggernauts,” and their alien masters known simply as “Invaders,” arrived from outer space and wrought havoc upon the world. They had no interest in communicating with us – they sought only to wipe us off the face of the planet. The end of mankind was at hand...

Dateline: 2018
Against all odds, we fought back against the invasion fleet, and after one final, fierce clash, we drove the aliens away and began the painful process of rebuilding. Now that we knew we weren’t alone in the universe, however, the nations of the world came together, began laying the foundations of a world government, and agreed to establish a multinational military power known as the “Earth Defense Force.” Dedicated to defending Earth against any further incursions from beyond the stars, members of the EDF are trained to battle any conceivable threat by any means necessary.

The EDF’s new ace in the hole is a special ops division known as the “Pale Wings.” Equipped with versatile jetpacks and energy weapons based on reverse-engineered alien technology, they’re ready any time of the day or night to crush the enemy from above.

And at the rear of EDF’s ranks, elite “Air Raiders” stand at the ready too, applying their tactical knowledge, high-tech gadgetry and precision bombardments to keep any potential threats right where we want ‘em: dead.

Dateline: 2019
After scarcely more than one brief year to get all our ducks in a row, the aliens have returned for an encore. But this time, the EDF is ready and waiting. Wait till they see what we’ve got in store for ‘em now...

Infantry
The grunt soldier, or Infantry, is the generic term for the EDF ground force and its individual soldiers. They form the backbone of the EDF Peacekeepers, and there are about 300,000 of them all over the world.

Infantrymen are skilled with weapons that cause kinetic damage, such as rifles and rocket launchers, and are combat experts skilled in many other types of man-portable weapons as well.

Pale Wing
The Pale Wings are an elite force who use special weapons and jetpacks. Because their gear needs to be lightweight, their armor is not as strong as the Infantry's.

Pale Wings use special weapons made with the Invaders' technology, but those weapons often consume the same energy they use to fly, so a skilled soldier must pay close attention to their energy reserves at all times.

Air Raider
Air Raiders are not keen on close-quarters combat, but that doesn’t mean they don’t have their place in bug extermination. They can survey the battle from afar and call for intense aerial bombardments, which can annihilate enemy forces over a wide area and often turn the tide of battle. Air Raiders are also excellent drivers and pilots, able to handle both tanks and gunships with ease.
