Activision has done some silly things in the past when it comes to promoting Call of Duty, but their latest stunt is actually a little bit cool: it's a bot that you talk to over Facebook Messenger.
Facebook Messenger bots are a new thing for developers, with Facebook rolling out a beta version of the Messenger Platform a few weeks ago.
"Whether you're building apps or experiences to share weather updates, confirm reservations at a hotel, or send receipts from a recent purchase, bots make it possible for you to be more personal, more proactive, and more streamlined in the way that you interact with people," Facebook says.
So naturally, the Call of Duty devs decided to give it a whirl. They released a couple of short videos over the weekend that seem like they'll fuel into the plot of Infinite Warfare, which is getting a huge reveal tomorrow.
It's the beginning of a trail of crumbs for Call of Duty fans to solve. But how do you actually "solve" the puzzle?
By talking to Lieutenant Reyes on Facebook Messenger.
The idea is to recover an access code for the SATO defence grid, and Lt. Reyes helps out by giving you the first letter: "G". He'll also ramble on about the battle currently taking place, and if you press him on that he'll reveal that the enemy from the first video is using a ship to hunt for the same codes as you.
The "ship" in question
If you want to know more about the lore, characters or armed forces, Reyes is only too happy to tell you. It'd be interesting to see just how many responses Infinity Ward has coded into the bot, although that might be something more apt for a GDC talk next year.
You can find all the answers and breadcrumbs, if you want assistance, on the official sub-reddit. The numbers and letters were hidden around the Nuk3town map in Black Ops 3 (as teased in the trailer).
Once you've put in the code — or just borrowed it from the internet — Lt. Reyes thanks you for your service and tells you to "return here for transmission". You can then ask for "New Orders", which starts a message chain with Corporal Rodriguez.
"Reyes said you'd be heading my way. I'll be here until the ball drops at 1600 GMT. Until then, make yourself comfortable," the bot writes.
Whatever the tease ends up being, we'll know more around 3:00 AM AEDT tomorrow.
