Despite Warhammer 40K: Space Marine 2 enjoying both critical and commercial success, fans continue to suffer from issues playing the game’s co-op mode and online component in general. While Space Marine 2 delivers an action-packed story mode, the game also features several ways to play online, both cooperatively and competitively. However, the game’s co-op mode is notoriously difficult to get working, with Space Marine 2 players feeling frustrated by an all-too-common matchmaking error.
