Call Of Duty : Modern Warfare 2
Requiring 25 consecutive kills (or 24 with the Hardline perk) this killstreak is the hardest to acquire in Call of Duty: Modern Warfare 2. Once used, a ten second countdown will display on all player's screens as the nuclear warhead, although invisible, falls to earth, and a siren will sound. Once the countdown expires, the entire battlefield will be engulfed in white light as the nuke explodes. Time will appear to slow, all vehicles and sentry guns will explode, and finally, all spawned players including the user die on the spot. A Tactical Nuke detonation results in an automatic win for the user and their team, no matter what the current score. Getting the Nuke requires a prolonged amount of camping, cautious gameplay and strategy. Because of this, Nuke Boosting has become increasingly prevalent, where two players sit in a corner of the map with a Tactical Insertion and one kills the other 25 (24 with Hardline) times until the Nuke is acquired.
