UPDATE: Teaser dialogue decoded.

Liara’s speech - portrayed as ever by Ali Hillis - was decoded by Soundcloud userMosaic Horse.

BioWare has since provided its own cleaned-up version:

Thank you to all the agents who decoded the footage.

Mass Effect 5.

“I can see it… How did we miss this?”

Liara can be heard saying.

As you’d expect, the teaser only throws up further questions.

Why is Liara working with the geth?

What have those pesky humans done now?

And why has no-one elected a better Council yet, even centuries later?

BioWare’s latest Mass Effect 5 art tease.

Some things never change.

“Although, they should know by now not to underestimate human defiance!”

“For interior use only.

I’d put a lot of money on this being our hero’s new spaceship home away from home.

Above the partly-constructed Relay’s ring, large ships can be seen air-lifting fresh pieces into position.

So, why are new Relays being built?

If so, it’s nice to know the quarians survived in the Mass Effect canon post ME3!

An animated version of this artwork has also been published viaTwitterfeaturing some mysterious-sounding audio.

Fans will no doubt be kept busy deciphering the sound clues on offer here.

A filename for a downloadable version of this video reveals it to show the Satherium System.

Happy#N7Dayfrom across the stars!

And that’s about it for this year’s N7 Day celebrations.

A few crumbs, yes, but better than nothing.
