Resident Evil: The Board Game – Into the Darkness ExpansionExpansion

From BoardGameGeek:

Tiptoe through the Third Floor and the underground cave system in tense new scenarios where you'll face rotating tiles, boulder traps, and poison. Watch out for the enormous Yawn's gaping maw, and the ensnaring webs of Black Tiger and her spiders... Dare you step into the darkness and take on these two huge new bosses, so big they engulf multiple squares? Including six gripping new scenarios, this expansion adds 8 hours of extra gameplay to your Resident Evil: The Board Game campaigns. Or, play each scenario as a terrifying standalone experience.
