CS2 weapon · SMG · both sides MP5-SD

Valve: “Nimble and stealthy for mid-range damage.” Often imitated but never equaled, the iconic MP5 is perhaps the most versatile and popular SMG in the world. This SD variant features an integrated silencer, making an already formidable weapon whisper-quiet.

You can land several hits — a helmeted head takes 2 even up close.

Economy context

  • MP5-SD alone$1,400$2,700 left

Kill reward $600 — 3 kills pay the gun back. Armour: Kevlar $650, with helmet $1,000 (Valve’s items_game.txt).

Counterplay tips

  • Fight it beyond 14.38 m: past its standing accurate range even the first shot is not sure to land.
  • Catch it moving: on the move its first shot is only sure within 4.98 m.
  • It needs 8 chest hits at 15 m against armour — trade it rather than duel alone.
  • It moves at 235 u/s — expect it to reposition quickly.
  • Drop its holder first: they lose a $1,400 gun, and each kill it makes pays them $600.

No — 2 hits to a helmeted head at 30 m (50 each).
