Nintendo working on an alien-themed game?

Nintendo is up to something. On April 2 the Mario maker filed a new trademark application for a game called "Code name: S.T.E.A.M. Strike Team Eliminating The Alien Menace."

The filing (via Gematsu) is listed as a video game, but that's all we know about it. Presumably, it will involve laying waste to some enemy alien faction in some manner.

The trademark application, filed with the United States Patent & Trademark Office (USPTO), lists Nintendo of America as its owner. We have reached out to the company for comment.

PAX East will be held this week in Boston, Mass., but Nintendo is not attending. Tomorrow, Nintendo will hold a special Super Smash Bros.-themed Nintendo Direct at 6 p.m. EDT.
