Below from the Call of Duty Wiki:
Cranked, also known as PCP as an April Fool's day joke, is a game mode in Call of Duty: Ghosts and a custom game option in Call of Duty: Infinite Warfare. The gametype is similar to Team Deathmatch with two teams competing to earn kills. Whenever a player gets a kill, they earn a "Cranked" bonus, giving them faster movement speed, reload, and ADS. Upon getting the bonus, the player is given a 30 second timer. After each kill or assist the player earns, the timer will reset. If the player fails to get a kill or assist within the time limit, they will explode and die.
The first kill a player gets upon spawning or respawning will add one point to the team's score. Each "Cranked" kill or each kill the player gets with the timer will add two points to the team score. The first team to reach 150 points wins the game.
