Ok. So, I can’t say with 100% certainty that this isn’t legit, but I can say with 95% certainty that it isn’t legit. The closest title the game mentioned here (that I can find at least) is a Facebook strategy game titled Stormfall: Age of War, which came out back in 2012.
While Stormfall is made by Plarium, a game company would not be looking for test players 2 years after said game has released (at least none that I know). Long story short: No thank you, sir, because this says virus to me about ten times over.
I got the same thing. Definitely shady. /:
