SOF flood outbreak

It’s been awhile since I played HW2, but did they ever actually discuss the flood outbreak while the SOF was floating through space?? I watched a video on it the other day and I just wondered if they ever talked about it sometime during HW2. The only reason I think that they didn’t talk about it was that the game came out before the outbreak was actually canon, which would explain why they still had basically all of the crew from the end of HW. Because the way the story tells it, the majority of the crew was infected. So does anybody know if they did talk about it and I’m just stupid or if they just left it out of the story.

From what I remember they don’t explicitly mention it in HW2, but I don’t think that de-canonizes the flood outbreak.
