Warhammer 40,000: Space Marine 2's PC launch has sparked controversy over its mandatory inclusion of Epic Online Services (EOS), even for Steam users who don't utilize crossplay. While Focus Entertainment clarified that linking Steam and Epic accounts isn't required for single-player, Epic Games confirmed to Eurogamer that crossplay mandates EOS for all multiplayer titles on their store. This requirement extends to games on other platforms, forcing developers to integrate EOS to offer cross-platform functionality. While developers aren't obligated to use EOS, it's presented as the most straightforward solution for achieving crossplay across PC storefronts, especially given its free-to-use nature and pre-built functionalities.
This mandatory inclusion has ignited a firestorm of negative Steam reviews, primarily focusing on the unannounced EOS installation. Concerns about "spyware," the Epic Games launcher, and the extensive EOS EULA, particularly regarding data collection, fueled the backlash. However, many games, including notable titles like Hades, Elden Ring, and Hogwarts Legacy, also utilize EOS. The prevalence of EOS, particularly due to its integration with the widely used Unreal Engine, suggests this controversy might stem from a knee-jerk reaction to a common industry practice.
Ultimately, the decision to retain EOS rests with the player. While uninstalling EOS is possible, it disables crossplay functionality. Despite the negative reception surrounding EOS, Space Marine 2 has received largely positive reviews for its gameplay, with Game8 awarding it a 92, praising its faithful representation of the Space Marine experience and its status as a superb sequel.
