Warhammer 40,000: Space Marine 2's PC release has ignited a firestorm of controversy, not from its brutal gameplay, but from an unexpected foe: Epic Online Services (EOS). This article explores the developer's rationale and the resulting player backlash.

Space Marine 2's Mandatory EOS: Crossplay's Unexpected Price

The launch of Warhammer 40,000: Space Marine 2 has been overshadowed by the mandatory inclusion of Epic Online Services (EOS), even for players who purchased the game on Steam and don't use crossplay.

While Focus Entertainment clarified that linking Steam and Epic accounts isn't required to play, Epic Games confirmed to Eurogamer that crossplay is mandatory for all multiplayer titles on the Epic Games Store. This policy necessitates EOS integration in Space Marine 2, regardless of player preference.

An Epic Games spokesperson stated, "Cross-play across all PC storefronts is a requirement... ensuring players and friends can play together regardless of where they bought the game. Developers can choose solutions, including EOS, which may require a secondary installation for the social overlay."

The core issue: While developers aren't forced to use EOS, it's the easiest way to meet Epic's crossplay requirement for games on their store. EOS offers pre-built solutions and is free to use.

Player Outrage Over EOS's Mandatory Installation

While some embrace crossplay, many players strongly oppose the mandatory EOS installation. Concerns include its perceived nature as "spyware," a preference to avoid the Epic Games launcher, and the lengthy, potentially confusing EULA, particularly regarding data collection (which applies to certain regions only).

This led to negative Steam reviews focusing on the unannounced EOS inclusion, despite it being separate from the Epic Games launcher. The controversy is amplified by the fact that EOS is used by hundreds of games, including major titles like Hades, Elden Ring, and Hogwarts Legacy, often due to its integration with the widely used Unreal Engine.

The question remains: are these negative reviews a knee-jerk reaction, or a valid concern about a prevalent industry practice?

Ultimately, players can uninstall EOS, but this means losing crossplay functionality.

Despite the backlash, Space Marine 2 remains critically acclaimed. Game8 awarded it a 92, praising it as a "near-perfect" sequel. For a detailed analysis, see our full review!
