However, I noticed that the Grand Hyatt has a particular motif repeated across the stone floor of its lobby. The symbol seemed strangely familiar, but I couldn’t quite place it. It wasn’t until I noticed the pattern covering the floor of an elevator that it hit me–the GrandHyatt is clearly a front for Umbrella.
Vanity is a terrible weakness, and Umbrella falls for it every time. No matter what sort of secret laboratory or hazardous waste facility they may construct, they always brand the hell out of everything with their logo. It’s like they were worried that people wouldn’t know who was responsible for releasing zombies upon the unsuspecting populous.
And as we can see, here in the Grand Hyatt Taipei, the tradition continues. We can safely surmise that the hotel is either an Umbrella front, or is innocently reusing a building that was originally constructed for the purposes of nefarious research. Either way, it’s obvious that a secret lab lurks beneath the hotel. We just need to find the Jack of Spades Key to enter the locked door that will lead us underground.
