The Resident Evil series has long been a staple of the survival horror genre, known for its intense gameplay, terrifying enemies, and immersive storyline. Resident Evil 5 built upon this reputation, introducing a co-op gameplay mode that allowed two players to play through the game's campaign together. This feature was praised by critics and players alike, enhancing the overall gaming experience. However, on the PC version, Capcom, the game's developer, made a surprising decision: to limit split-screen co-op to controller users, effectively excluding keyboard and mouse players from this feature.
