Resident Evil: Operation Raccoon City received mixed reviews from critics. Aggregating review websites GameRankings and Metacritic gave the Xbox 360 version 51.08% and 52/100, the PlayStation 3 version 48.17% and 52/100 and the PC version 40.00%.Official Xbox Magazine gave it a score of 7/10, as a "satisfying blend of gunplay and teamwork." Destructoid said that the game "suffers from poor design...but that doesn't stop it from being a genuinely good time that should satisfy anybody looking for a hardcore romp."The Guardian said "It's important to bear in mind that it's best experienced multiplayer rather than solo. But it's great fun and adds a fresh spin to a key time and place in the Resident Evil universe." GameShark said: "Raccoon City isn't the next real Resident Evil game (though its improved controls do bode well for that game). Instead, it's a mostly solid third-person, cover-based shooter set in the same universe."
Some reviews were negative. IGN's review stated "An actual zombie outbreak would have been less tragic," calling the game "little more than a poor man's SOCOM and a destitute man's Resident Evil." GameSpot echoed these sentiments, stating that the game "is a frighteningly flawed action-heavy spin-off that withers in the shadow of its superior alternatives".GamesTM gave the game 3/10, criticising the teammate AI, glitches, and unimaginative set pieces after having played the single player mode They would revisit the game after its release to review online options, and largely came to the same conclusions, criticising the poor AI and mission design, although they did state that the game was better online than offline. Once again, they awarded the game 3/10. Eurogamer called it an "under-designed and under-produced nightmare...that delivers the bare minimum in every category." GamesRadar summed up its review with "poor design choices, narrative missteps, and technical issues combine to make this one of the worst Resident Evil games to date."Game Informer ended their review with "Not even online play is enough of a reason to warrant checking out this botched experiment with the Resident Evil brand."Edge gave the game a 3 out of 10, concluding that "it’s hard to see what this distinctly low budget shooter has to offer beyond yet another return visit to already blood-saturated and well-trodden ground." Game Revolution even went as far as to say that the game hurt the Resident Evil brand name, and that the game "should never have had the Resident Evil name attached to it. It smacks of purely business-oriented decision-making. Players are guaranteed to walk into the store and see that name and expect something completely different. It's not fair to consumers and Resident Evil fans alike.
