100 kills with explosives
Danger Close is a tier two perk in Call of Duty: Modern Warfare 2 that increases explosive damage by 40%. The Pro version increases the damage of all explosive killstreaks, such as Chopper Gunner or Harrier Strike, by 40% and is unlocked by getting 100 kills with explosives while using this perk. It replaces Sonic Boom from Call of Duty 4: Modern Warfare and Fireworks from Call of Duty: World at War.
This perk is unlocked at rank 33 and is the last tier two perk unlocked.
- The title that one gets after getting 250 kills with explosives using this perk is 'Sonic Boom' a reference to the perk which Danger Close replaced from Call of Duty 4: Modern Warfare.
- Danger Close is often used in conjunction with One Man Army to gain practically a infinite amount of grenade launcher ammo. However, this is very frowned upon by other players.
