If that footage is in-engine I'll eat my hat.
"This is a game we’re playing around the office right now" is extremely provocative.
Edit: ah, you removed your request for citation. Doh. :)
The article says:
> This is the video of a real-world, first-person shooting game that Magic Leap says it was going to show at TED this week.
At first I parsed that as saying Magic Leap was going to show the game at TED, but what I've seen other articles say is that they were going to show this video at TED.
There is no way this is in-engine AR. This has to be a concept video for a prototype they're working on.
For them to say they're playing this around the office isn't exactly a lie -- they may very well be working on a prototype that has similar mechanics -- but it's bending the truth.
