Warhammer 40,000: Space Marine 2's PC launch sparked controversy due to the mandatory installation of Epic Online Services (EOS), even for Steam users not interested in crossplay.

EOS: A Crossplay Mandate

Epic Games confirmed to Eurogamer that crossplay is mandatory for multiplayer titles on their store, requiring EOS integration. While Focus Entertainment clarified that linking Steam and Epic accounts isn't required for single-player, EOS remains necessary for cross-platform play. This policy forces developers offering crossplay on the Epic Games Store to utilize EOS, even if it's not desired by all players.

An Epic spokesperson stated, "Cross-play across all PC storefronts is a requirement... Developers are free to choose any solutions that meet this requirement, including Epic Online Services..." Essentially, EOS offers a convenient, free solution for developers to comply.

Backlash and the EOS Debate

The mandatory EOS installation triggered negative Steam reviews. Concerns about perceived "spyware" and the lengthy EULA, especially regarding data collection in certain regions, fueled the backlash. However, many games utilize EOS, often due to its integration with the widely used Unreal Engine.

The controversy highlights a broader industry practice. While players can uninstall EOS, they lose crossplay functionality. The negative reviews raise questions about whether the reaction is a knee-jerk response or reflects legitimate concerns.

Despite the criticism, Space Marine 2 remains critically acclaimed, receiving a 92 score from Game8, praising its gameplay and faithfulness to the Warhammer 40,000 universe. The game's quality overshadows the ongoing EOS debate for many.
