The latest teaser for Activision's still unannounced first-person shooter Call of Duty: Infinite Warfare shows a brief video and a link to chat with a Facebook Messenger bot to help crack a code.

The video shows "Lt. Reyes" breaking through the previous teaser video from the enemy Settlement Defense Front. He tells you to contact him on Facebook Messenger. When you go to the provided link, you appear to be chatting with a Lt Reyes bot who tells you to crack a code to help them out.

The code can apparently be found inside the Nuk3town map in Call of Duty: Black Ops III, which was the place Activision used for previous teasers for Infinite Warfare. If you own the game, feel free to go into the map and find the code to assist "Lt. Reyes".

The official reveal for Call of Duty: Infinite Warfare looks like it will be released sometime in the coming week. The game, which is rumored to feature space battles, will also be sold in a Legacy Edition, which will come with a code to download a remastered version of Call of Duty 4: Modern Warfare.
