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";[34] 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."[35] Though Jim Sterling gave Earth Defense Force 2025 a negative review, they did acknowledge that the series "has managed to earn itself a fierce cult following through audacity alone".[36]
