Chris Evans
not only plays a hero in Captain America, but he's also doing his part to make the world a better place in real life.

The Marvel star has teamed up with Omaze to raise money for Christopher's Haven, a Boston-area apartment complex that provides temporary housing for families of children who are being treated for cancer at nearby hospitals.

To raise money, Evans -- a Massachusetts native -- is giving fans a chance to participate in an Escape Room adventure with him. To demonstrate the concept of an Escape Room -- in which a group of people have to solve puzzles and riddles to get out of a locked building -- the 35-year-old actor set up an elaborate prank at a Comicazi comic book store in Boston.

Setting up a Captain America doll with a hidden speaker, Evans sat in a hidden room and surprised shoppers browsing the store by talking with them through the doll.

After convincing them to accept a challenge, the random shoppers got a chance to participate in an Escape Room adventure by solving puzzles set up inside and outside the store, all while Evans watched on a series of hidden cameras.

As the (sometimes hesitant) participants carried on with the adventure -- which included finding code numbers, yelling "Hail Hydra" in public to flush out secret operatives and using tools to solve puzzles -- they worked their way toward an awesome prize: meeting Evans in person.

If this is fun some random people had without even expecting it, it seems like participating in an Escape Room with Captain America himself would be a once-in-a-lifetime experience for whoever wins the Omaze event.

Fans can enter for a chance to win at Omaze.com/chris. All that is required to enter is a minimum donation of $10, which benefits Christopher's Haven. The campaign continues through Feb. 3.
