Tactical Mask renders the player immune to the effects of Nova Gas. Its Pro version reduces the effects of Flashbangs and Concussion Grenades on the player by 90%. This is to say that if hit by a Flashbang, the player's vision will dim for a second before returning to normal. If hit by a Concussion Grenade, the player's vision will blur as if stunned, but movement and turning speed will be unaffected. This lasts for about two seconds before the player's vision returned to normal. It also reveals the general direction of any enemies that are hit with the player's Flashbangs or Concussion Grenades via a small yellow directional indicator near the crosshair. If multiple enemies are stunned or blinded by the player's tactical grenades, multiple arrows will show up on his crosshair.
- Flash Kills — Kill 20 enemies that are blinded by your Flashbang.
- Concussion Kills — Kill 20 enemies that are stunned by your Concussion Grenade.
- Nova Gas Kills — Kill 20 enemies poisoned by your Nova Gas.
