UPDATE 3.30pm: Moscow commuters beware - we've been told that while the Amiibo interacts with the gate's locking mechanism and changes its light to green, the gate itself will still close on you should you try to pass through.
Here's a more detailed explanation from Eurogamer reader and Moscow resident Vyacheslav Mostitsky:
"The confusion here is that the gates in Moscow metro seem to be opened all the time, but in fact they're actually closed. You need to place your card on the reader to 'unlock' it and go past them. If you don't, the gates quickly shuts right before you, possibly injuring your private parts.
"You can see that green light disappear really quickly - it's supposed to stay green until you're past the gates."
ORIGINAL STORY 28/11/14 2.55pm: A Russian Nintendo fan has filmed his Samus Amiibo toy apparently interfering with the ticket barriers of the Moscow metro.
The NFC figurine is shown interacting with the gate's own NFC-reading sensor. After a second, the gate's light turns green.
Repeated touches of the Amiibo's base to the gate's reader allow Samus' owner to open and close the gate several times.
As yet there have been no reports of Amiibo figurines working as Oyster cards on the Tube.

Meanwhile, a rare production error has resulted in another Samus Amiibo figurine with two arm cannons.
Samus usually wields her arm cannon on her right-hand side. The standard Amiibo design reflects this, but a production error has seemingly resulted in a special dual-wielding variant.
Several other production error Amiibos have also been photographed out in the wild - although many are less picturesque (see below).
Nintendo's first wave of Amiibo figurines launch today in the UK alongside Super Smash Bros. for Wii U. Three more waves have already been announced for launch in December and into the new year.
