EARTH DEFENSE FORCE: WORLD BROTHERS is a cooperative shooter with a third-person view. It can also be played alone. It's also part of a larger series. This spin-off from the serial video games of the franchise and other offshoots is distinguished by voxel graphics in a cubic style. Another difference is that here the events take place in another dimension on an alternative version of our planet. In the story, a celestial body (here it is square) split into pieces after the invasion of giant insects. The alien invaders are led by the Dark Tyrant. Members of the EDF (Earth Defense Force) organization are fighting with them. The third feature of the project is a lower entry threshold than in other titles. Guns are now divided into 10 types. To gain access to the entire arsenal, you need to upgrade.

In Earth Defense Force: World Brothers, players fight large ants, wasps, spiders and other such creatures, as well as kaiju. The battles take place in Japanese cities, the outskirts of villages, caves, deserts and other locations. Maps have become more varied than before. The story campaign is divided into 60 missions. Initially, 3 types of difficulty are available, but as you progress, new levels open up. The user now controls a squad of 4 characters. If there are not enough live partners or in a single player, the rest of the team members are controlled by AI. Each hero has a unique skill and weapon preference (this concept replaced the old class system). During the stages you can find and unlock new heroes. You can switch between them at any time.
