What beats the SG 553?

Economy context

  • SG 553 + Kevlar + helmet$4,000$100 left
  • SG 553 + Kevlar$3,650$450 left
  • SG 553 alone$3,000$1,100 left
  • Galil AR + Kevlar + helmet$2,800$1,300 left
Kill reward $300 — 10 kills pay the gun back. Armour: Kevlar $650, with helmet $1,000 (Valve’s items_game.txt).

Counterplay tips

  • Fight it beyond 23.78 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 1.12 m.
  • It needs 4 chest hits at 15 m against armour — trade it rather than duel alone.
  • It moves at 210 u/s — re-peek fast; it is slow to follow.
  • Drop its holder first: they lose a $3,000 gun, and each kill it makes pays them $300.

Yes — 114 damage to a helmeted head at 30 m.
