New email scam or real invite?

I just received an invite for the new RuneScape game, and the email says it’s called Aqua Coyote. The sender's address is:
The RuneScape: Project Survival Team [[email protected]](mailto:[email protected]).

Is this a scam or a legitimate invite? The email also included a Steam key for the game Aqua Coyote.

PS: I included the name because it is temporary as stated in the email. Still no official statement anywhere, looks very phishy
