The building looks like a face because of that thing coming from the ship thing.
The "building" is a Colossus, it's from the game Shadow of the Colossus, they all look like buildings but with fur on some of their parts, and have some glowing spots on them that point out weak points to stab them in
I think hitting them in their weak points is the only way to take them down in Shadow of the Colossus and anything else is a severe waste of time or something
Shadow of the Colossus looks nice once you get to the battling, but it's a really wide open landscape, so you're just traveling for hours and hours looking for the next enemy to take down, so it's got a lot of boring parts in between
