N31L

"Please, do not disassemble. N31L lives."

- N31L's first quote upon being activated

N31L, also referred to as Neil as well as KITT (Knight Industries Two Thousand), is a character featured in Call of Duty: Infinite Warfare, in the Zombies maps Zombies in Spaceland and The Beast from Beyond. In Zombies in Spaceland, N31L functions as a utility for the player, offering challenges that reward the player with a set amount of tickets whenever they are completed, and in The Beast from Beyond, N31L has been upgraded to N31L-X, providing the main power to the map, and also an important part in the main quest.

When all five challenges in one of N31L's three sets are completed in Zombies in Spaceland, the player will have the option of calling in David Hasselhoff as a friendly AI. However, the Seti-Com cannot be built or turned in while Hasselhoff is active. Fully constructing N31L will grant the player a large XP bonus, as well as a contribution towards the Sticker Collector achievement/trophy.

After all three waves of challenges are complete, Hasselhoff can be called in at any time at the price of $5000.
