A digital digital pet as it were.
Call of Duty: Modern Warfare

Infinity Ward managed to implement a real-time wristwatch feature in Call of Duty: Modern Warfare. This would allow you to see what time it was by actually glancing at your wrist while in game. That's kind of neat, but also rather useless.

However, it was because of this basic feature that the team discovered they could do some rather out there ideas. For instance, they thought about stat tracking and other features you might find in a modern smartwatch or fitness tracker. Those idea just kept ballooning until eventually they hit upon the idea for adding a digital pet.

They call them Tamagunchi and yes, they are indeed inspired by the real Tamagotchi that were all the rage in the 90s. If you choose to equip one of these on your character in multiplayer and the co-op Spec Ops mode, you will get to raise the digital pet as your own. You will need to feed it and care for it. Of course, the "food" you feed it is kills. Get a sick killstreak and it will "chirp with delight as you rack up the points." If you suck, it'll get mad at you.

The idea was birthed from art director Joel Emslie. Here is what they had to say about how it will react to your performance.

"This little thing on your wrist, every time you get a string of kills, it goes, 'Ya-ta!' and it makes a little noise, then you look at it, and it evolved out of an egg. Tamagunchis are fed by the player’s performance in multiplayer. It’s just this little active wristwatch thing.

"If you don’t take care of your Tamagunchi, it will rot and die."
But that won't happen to yours, right? You aren't a monster, right?

Infinity Ward notes that you don't have to equip the Tamagunchi if you don't want to. For those of you who aren't against the idea, you can start raising your digital digital child when Call of Duty: Modern Warfare releases on October 25 for the PC, PlayStation 4, and Xbox One.
