Earth Defense Force, known in Japan as Chikyū Bōeigun (Japanese: 地球防衛軍; lit. Earth Defense Forces), is a science fiction third-person shooter video game series by D3 Publisher, originating as an offshoot of the Simple series. As of 2024, it consists of eleven entries and six main installments, developed and published by various studios and publishers since 2003, primarily Sandlot. The series follows the titular Earth Defense Force (EDF), an international armed force that fights to defend Earth from alien invasions by extraterrestrials that field massive insectoids in their war against humanity. Individual Earth Defense Force releases generally receive mixed or average reviews, but the series has been lauded for its simplistic but entertaining premise and campy tone, and it maintains a strong cult following.

## Premise

[edit]

Earth Defense Force has roughly five separate continuities as of 2024. However, in general, all entries in the series share a similar basic premise, following the Earth Defense Force (EDF), a specialized multinational defense force established and supported by every country and staffed by the world's militaries, tasked with defending Earth and humanity from external threats. The vast majority of Earth Defense Force installments are set after the discovery of the Ravagers, an intelligent and organized alien race, with the formation of the EDF sometimes explained as being a precautionary measure. The Ravagers prove to be hostile and attempt to invade Earth, deploying massive insectoids such as ants, ticks, pillbugs, beetles, hornets, and spiders to destroy Earth and exterminate humanity; this prompts the full-scale deployment of the EDF to fight back and repel the alien invasion.

The series installments are mostly set during the 2017 invasion, during later invasions in 2019 and 2025, or, in different continuities such as the one introduced in Earth Defense Force 5, 2022 and 2026. Several conflicts also feature alien races and enemy types distinct from the Ravagers and the insects, including the bipedal frog-like Colonists (their "resemblance" to humans based on generic characteristics such as having two eyes is a running gag), the advanced grey alien-inspired Cosmonauts, the reality-bending but genocidal Primers, assorted robots and probes fielded by the aliens, and various kaiju.

The EDF largely consists of infantry units and armored fighting vehicles, and the series entries typically depict the player as a member of either regular infantry or elite special forces. The game's playable characters are represented by different character classes ("armors") that vary depending on the game, but across most entries the basic armors are the "Infantry"/"Trooper"/"Ranger", a standard all-rounded soldier wielding standard service weaponry and explosives; the "Pale Wing"/"Wing Diver"/"Jet Lifter", a female special forces scout with a light but vulnerable jet-powered winged suit; the "Fencer", a support soldier in a heavy but slow exoskeleton wielding heavy guns, powerful swords, and usually also a ballistic shield; and the "Air Raider", a logistical technician reliant on controlling close air support, drones, and requisitioning usable combat vehicles such as tanks, infantry fighting vehicles, helicopters, hoverbikes, and mecha.

It was the first game in the series to be developed outside Japan and also the first to feature online co-op. It is essentially an "Americanized" rendition of the Earth Defense Force series, and follows American EDF forces as they defend the United States from aliens and insects, presented as a non-canon "side story" to Earth Defense Force 2017.

Earth Defense Force: Iron Rain is a spin-off developed by Yuke's for the PlayStation 4 and Microsoft Windows.[17] Announced at TGS 2017, it is a non-canon spin-off story intended for Western audiences (similar to Insect Armageddon) with little relation to Sandlot's entries and an overall presentation intended to be "more serious than the series' traditional campy tone."[18] Set in an alternate 2040 following years of conflict since the first alien invasion in 2028, the game follows the now-downtrodden EDF's Blast Team as they attempt to fight back against a world largely claimed by the aliens and insects, while also clashing with the Kindred Rebellion, a rebel army composed of disillusioned EDF soldiers.

#### Earth Defense Force: World Brothers (2020)

[edit]

Earth Defense Force: World Brothers is a voxel graphics spin-off developed by Yuke's for the PlayStation 4, Nintendo Switch, and Microsoft Windows. It was released in Japan in 2020 in Japan and in North America and Europe in 2021.[19][20][21][22] It features character-switching gameplay unique for the series, allowing the player to control a squad of four characters. World Brothers features a more light-hearted plot and tone than the rest of the series, and is intended as an homage to the series as a whole, featuring characters and references from previous entries. The plot revolves around the EDF's fight against aliens who manage to physically shatter Earth into multiple pieces, cutting off the EDF's divisions and preventing aid and resupplies. Unbeknownst to them, the aliens are under mind control by the Dark Tyrant, an evil entity seeking to destroy Earth; in a twist on the series' usual premise, the EDF tries to free the aliens and insects to team up with them against the Dark Tyrant.

#### Earth Defense Force: World Brothers 2 (2024)

[edit]

Earth Defense Force: World Brothers 2 is a voxel graphics spin-off developed by Yuke's for the PlayStation 4, PlayStation 5, Nintendo Switch, and Microsoft Windows. It was released September 26th, 2024.[23] The game features a similar plot to the original World Brothers, with the EDF investigating another shattering of Earth, this time caused by the Gaiark, an entity within the planet itself.[24]

Despite generally mixed reviews, the Earth Defense Force series, particularly from Earth Defense Force 2017 and onwards, has been described as having a cult following. Joe Juba of Game Informer defined Earth Defense Force 2017 as a cult classic, stating that "the developers at Sandlot clearly want to tell a story about humanity's struggle against giant invading ants and robots, and the passion for that story shines through despite its technical shortcomings";[35] in reviewing Earth Defense Force 5 five years later, he similarly opined that the series has "always had a single-minded commitment to one simple truth: It's fun to use weird weapons to blast lots of aliens."[36] Though James Stephanie Sterling gave Earth Defense Force 2025 a negative review, she did acknowledge that the series "has managed to earn itself a fierce cult following through audacity alone".[37]
