Earth Defense Force games have traditionally been M-rated affairs. Earth Defense Force: World Brothers, the new spin-off game from Yukes and D3 Publisher, is a more family-friendly entry with colorful and blocky voxel graphics. World Brothers still has lots for EDF fans to love, though, including 4-player online co-op and copious humor and fan service. Its also the first EDF game on Nintendo Switch, in addition to PlayStation and Steam.
