Marvel Studios' newly-launched Captain Marvel website has revealed there might just be a lot more Skrulls on that train than we first assumed.

If you click the "PLAY THE GAME" button on the retro website, players are challenged to identify who is and isn't a shape-shifting Skrull. Of the eight characters, four are Skrulls, including the old lady Brie Larson's Carol Danvers beats down in trailers and promotional clips. This could indicate that there are more Skrulls in this scene than previously thought.

It remains to be seen if any of these newly-identified Skrulls will help their ally out during the scene, and it's entirely possible they won't end up actually being Skrulls in the film. Still, the game really emphasizes how hard the Skrulls make it to trust otherwise normal looking people.

The rest of the website is a throwback to the '90s and allows fans to view multimedia such as movie images, trailers and character portraits. The site also allows fans to buy tickets to see the Marvel Cinematic Universe's strongest superhero take down the alien invaders.
