Earth Defense Force 2017, known in Japan as Chikyū Bōeigun 3 (地球防衛軍3?, lit. "Earth Defence Force 3"), is a third-person shooter developed by Sandlot, and published by D3 Publisher, for the Xbox 360. It is the follow-up to Global Defence Force, and is the first game in the Earth Defense Force series (as well as the first game based on D3's Simple series of budget games) to be released in North America. Earth Defense Force 3 was the best selling Games on Demand game in Japan for 2009.[1] The game was released on the PlayStation Vita in Japan on 27 September 2012.[2] It was released digital-only in North America on 8 January 2013[3] and in Europe on 16 January 2013.[4]


In the year 2013, radio waves from deep space are picked up by scientists, proving to humans the actual existence of alien life. In the year 2015, the Earth Defense Force, a unified multinational military organization sponsored by nearly every country, is established in case the aliens prove to be hostile.

EDF ground forces are formed around three basic groups; Scout Teams, Ranger Teams, and Storm Teams, which fulfill recon, infantry, and special ops functions, respectively. They are supplied with the latest weapons and equipment, and have hundreds of thousands of soldiers stationed on every continent. However, half of the people weren't so sure if these extraterrestrials would be proven to be a threat or menace.

But then two years later, (which was the year 2017) first contact is made when hundreds of UFOs proceed to hover over every major city across the globe, led by a massive mothership positioned over Tokyo, Japan. The aliens, which politicians have called them Ravagers, initially make no aggressive action towards humanity. As the EDF is mobilized, giant acid spitting insects resembling ants begin to appear and attack civilians. The protagonist is an unnamed Captain in Storm 1, a Japanese unit regarded as the best in the EDF, and helps exterminate the ants in Tokyo. Soon after, the UFOs start releasing more ants onto the ground, proving their hostile intentions. An air assault is attempted on the mothership, but is utterly destroyed by alien gunships. Giant mecha and spiders are added to the fray, which contribute to already heavy losses. After weeks of brutal urban warfare, the surviving EDF forces abandon the cities and begin a guerrilla campaign in the rural areas.

While patrolling the Japanese countryside, Storm 1 is informed by command that an extensive alien nest is being built underground. From this nest, the Ravagers will be able to spawn an infinite number of bugs and bypass EDF defenses. Intelligence provided by Scout Teams shows that a single alien Queen is at the center of the nest, and its destruction will stop the production of the rapidly multiplying bugs. Storm 1 assaults the nest with the help of all available Ranger Teams, and successfully kills the Queen.

A few days later, Storm 1 assists a Scout Team with monitoring the mothership, which has landed on the Japanese coast and appears dormant, damaged, and defenseless. Oddly, it is observed sucking in huge amounts of air and releasing carbon dioxide, implying that the ship is more than a synthetic machine, and may be the hive intelligence controlling the Ravagers . Command orders the Teams to assault the mothership with heavy weapons, but it re-activates and wipes out the Scout Team.

Before the Ravager mothership retreats, it drops a massive four-legged mecha on the coast, which uses a powerful plasma cannon to assault EDF positions. Storm 1 destroys the mecha before it can cause too much harm, and later neutralizes several cyborg creatures of Godzilla proportions. While the Japanese contingent of the EDF continues to hold out, the rest of the world is soon overrun and enslaved. Japan stands as the last unoccupied territory.

All remaining insects and mechs on the ground make a beeline to the bombed-out ruins of Tokyo, where the mothership has stopped to repair and arm an enormous cannon, capable of destroying anything in its path. The remaining EDF forces move to block the Ravager advance so Storm 1 can destroy the mothership. In a climactic battle, Storm 1 focuses fire on the weak spots the cannon has revealed, and the mothership crashes to the ground, exploding in a huge fireball. The remaining Ravager forces become disorganized and flee.

The Earth Defense Force begins operations to free the occupied areas of Earth, and by 2018 the last of the Ravagers are wiped out. With the planet finally liberated, a collective chant of "EDF! EDF!" is heard across the globe.


The player takes control of an EDF soldier who is part of the elite unit Storm 1. To fight these alien forces the player can access over 150 weapons in the game, ranging from assault rifles and sniper rifles to rocket launchers, grenades and laser weapons. Only two weapons may be selected for each mission. Some levels also contain vehicles which can be commandeered; a tank, a helicopter, a hoverbike and a bipedal mecha are available. The game takes place across 53 levels featuring destructible environments, taking place in settings such as cities and underground caves.[5] There is no penalty for collateral damage that is inflicted on the environment by the player, for instance buildings will crumble after sustaining a single hit from a rocket launcher or grenade. Other EDF soldiers can be recruited or followed, and attack enemies on sight, as well as provide radio chatter.

There are five difficulty levels. More effective weapons are dropped by the enemies in the game at the higher difficulty levels, encouraging players to repeat the missions. In addition to weapons, armor enhancements which function as permanent maximum health bonuses are dropped along with healing items.

PlayStation Vita port[edit]

A PlayStation Vita version of the game was announced on June 5, 2012 as Earth Defense Force 3 Portable.[6] The new version will include both local and online co-operative play,[7] as well as the return of Palewing from Earth Defense Force 2.[8] The game was released on September 27, 2012 in Japan.[9] It was released digital-only in North America on 8 January 2013 and in Europe on 16 January 2013 as Earth Defense Force 2017 Portable.


Reviewers pointed out the game suffered from relatively poor graphics, a lack of many standard features and characteristically poor voice acting. However, the game still received solid reviews from western critics, whose general consensus was that the game is "inexplicably fun".[10] Some advocate it as a "gamers' game" with nothing in the way of the pure game, like Kieron Gillen in his 9/10 Eurogamer review;[11] the game's strong emphasis on arcade-style gameplay, with massively destructive weapons and hordes of enemies, suggests that this may have been the driving philosophy behind its design. Some outlets however, have claimed that the game pales in comparison to its predecessor, which had a larger range of enemies, missions, weapons and a second playable character.[12]

Earth Defense Force 2017 holds a GameRankings score of 70.66%.[13]
