Tactics using the SG550[]

Normal matches[]

  • The first shot is very accurate when you are standing still.
  • Stay stationary. Moving a little will affect the scope's performance.
  • Just fire without scope when engaging close enemies.

Zombie Mods[]

  • Camp in closed areas such as in vents to achieve the maximum performance.
  • A 30 round SG550 can deal around 1830 ~ 3660 damage. Feel free to kill a zombie that has 3500 HP or less.

Zombie Scenario[]

  • If the starting money is $7500, the player can purchase SG550 with cost $4200 and $1200 for 600 rounds of reserved bullets, giving the balance of $2100.
  • In Dead End, after the 2nd barricade has been penetrated, there's a fence which can be reached by jumping on other player's back. Players can stand on top of it and destroy the 6th barricade near the end of the path. This weapon is recommended when in a room which has no better weapons.
  • In term of assisting against bosses when there's no cash weapon, a proper skill while shooting the weakpoint and seriously dodging attacks could be useful.
  • Beware of its low rate of fire and long reloading time. This weapon is not recommended for counter-attack nor escaping zombie hordes. Switch to any weapon that anticipates the situation.

Human Scenario[]

  • Recommended for Annihilation maps only for 'non-cash' player. Can be done like other sniper rifles, aiming bosses will deal serious damage while assisting M95 users.
  • Since it has the largest magazine around semi-auto sniper rifles, it is recommended in Sidewinder to kill every enemy that lies or camps on rooftops, preventing other players to be injured.

Tactics facing a SG550 user[]

  • Jump to avoid being hit.
  • The SG550 is never accurate for the first shot. Use this advantage to kill the user quickly.
