I played on version 1.4.4—that's "Intravenous 2," and the campaign within is a remaster of the first game, but I think it will work on other versions as well (maybe even on the original first game, I haven't tried it). It's designed for those stuck on a certain episode and unable to progress due to a bug or broken script, or for those who simply want to see one of the endings.

Don't forget to back up your saves, as it may not work on newer versions!
