Capcom never said anything about the PC version lacking the feature before launch, which has understandably angered fans. The game'sstill marks out offline co-op as a feature, but an addendum underneath clarifies that the "PC version does not support offline co-op play in the Campaign or Raid Mode."
Which would be needlessly confusing, but sort of grudgingly acceptable, if it wasn't for that fact that the addendum was apparently added at the last minute right before launch.
"I don't have any info on the local coop/split screen," wrote a Capcom rep, "but I've alerted our PR and dev folks if there's any info on it. I'll be sure to let you know as soon as I have information. Just to be clear though, the game will eventually support online coop; it just won't be ready for Episode One. Same goes for the console versions."
Not everyone has the setup or the inclination to play local co-op of course, but it's been a pretty big part of the Resident Evil franchise for a while now. Whatever Capcom's reasons for cutting it on PC, not mentioning it before release and then changing the store page at such short notice is only going to alienate the PC audience.
has yet to officially respond. We'll keep an eye out for any further updates.
