Gameplay Description

A Medium Armored Operator, Frost comes equipped with three Sterling MK2 LHTs, nicknamed "Welcome Mats." The Welcome Mats are mechanical traps that can be used to incapacitate enemies.

  • Welcome Mats will immediately put any Attacker stepping on them into a DBNO state.
  • A trapped attacker cannot move or slow down the bleed rate. Attempting to move will only cause the Attacker to thrash around.
  • An Attacker caught in the Trap can only be rescued via manual revive, which will destroy the Welcome Mat.
  • Zofia's Withstand, Finka's Adrenal Surge, and Doc's Stim Pistol shots all cannot revive a player downed by the Welcome Mat.
  • The Welcome Mat can only put an Attacker in a DBNO state, even if that Operator has already been downed before. For example, if an Attacker happens to come across all three Welcome Mats in one game, they will be downed every single time.
  • An Attacker moving onto a Welcome Mat while downed will be instantly killed.
  • The Welcome Mat is fairly durable, being able to take a few gunshots (3-5) before being destroyed.
  • Melee will destroy them in one hit, but is not an advisable approach to destroy them given the nature of this gadget.
  • Picking up and resetting a Welcome Mat will reset its "health pool".
  • The Welcome Mat can be placed in most places on the floor, be it under a window or on the other side of a table, or even against the wall. Some tight spaces may or may not allow the Mat to be placed.
  • In Terrorist Hunt, AI Terrorists that step into a Welcome Mat will be instantly killed.


  • Any Operator that has Barbed Wire, which includes Frost herself, can use the wire to conceal Welcome Mats and make it harder for Attacking Operators to notice.
  • Frost works well with Bandit and Kaid, as the Welcome Mat is a mechanical gadget, meaning it cannot be destroyed nor affected by any electrified gadget. If an electrified set of Barbed Wire is placed on top of a Mat, any caught Attackers will die quickly.
  • Smoke also works well with Frost, as Attackers can easily get caught in a well placed Welcome Mat as they attempt to push through Smoke's gas, eventually succumbing to its toxic effects while they are downed from the trap.
  • Lesion is another Defender with a similar playstyle and gadget. If he is able to place his Gu Mine the right distance away from the trap, an incoming Attacker will get caught in the trap, with their leg triggering the Gu Mine, leading to a quick death.
  • However, if the Gu Mine is activated first, the Welcome Mat will cancel out the poison will not take effect.
  • As Frost’s Welcome Mat places enemies in a downed state, Caveira will be able to interrogate them.


  • Explosives can very easily destroy a Welcome Mat that's within their blast radius.
  • If swinging in from a window or vaulting over a Deployable Shield, an Attacker can quickly shoot a Welcome Mat with enough bullets to destroy it, preventing themselves from being trapped.
