No matter what, I'll always do some type of guide for every console Resident Evil game. Through the good and the bad, I'll write for them all, and that is a promise, so long as I have the spare time to do so.
Resident Evil: Operation Raccoon City is a true mix of good and bad. I think the good outweighs the bad when played in multiplayer though. Honestly, it is not as bad as reviews make it out to be. That still doesn't change the fact that it's a mediocre game overall to me. I often tell friends "It's loads of average fun!", mainly trying to pinpoint that I have fun with it, but I can see that the game is far from perfect. Here is my review for Operation Raccoon City.
But anyway, this guide covers all the USS Wolfpack campaign mission and I'm working on the downloadable Spec Ops (Echo Six) missions as they release. I'll fix up a full item list with all item locations before too long. With the Spec Ops campaign, the item locations probably won't be as detailed as they are in the USS campaign walkthrough, but all the intel will be listed in full detail for all campaigns.
This guide is very rushed and I think it's pretty half-assed compared to what I usually do... mainly from lack of motivation to write much for the game, but at least I can say that I did something for ORC. I can promise you, the RE6 guide will be WAY better than this one.
