Tokyo flood tunnels

Taikos.... Taikos in the deep.

Careful, looks like they anticipated you ducking into the sewer, they sent a sniper team to cut you off.

That's a deep cut but that was my 1st thought as well.

For me, it's the fact that that entire space could be filled with water.

I used to get the same eerie feeling lifeguarding as a kid, walking around in drained Olympic size pools. Always weirded me out for a minute. Like any second it could fill back up.
