The Flashbang is one of the two grenade types in the game, the other being the Frag Grenade. Just like the frag, the flashbang detonates on impact. It blinds everyone who sees it for approximately three seconds.
The Flashbang is unlocked at Rank 9. Rank 22 and Rank 32 each expand the carrying capacity by one, resulting in a maximum of three.
It is best used when turning corners, as an enemy may be around, and will be incapacitated long enough to be ambushed. Experienced players can throw flashbangs through windows to ensure that everybody in a building is blinded.
The CTK-84 Flashbang (Charbtek CTK-84 Incapacitating Grenade, Flashbang in-game) is an incapacitating grenade manufactured by Charbtek Corporation. Those affected are blinded for a maximum of four seconds, while those facing away from the blast or standing outside of a 10 meter radius are affected less.
Although the appearance of this grenade in multiplayer is rare, the flashbang is proven useful with the Stealth perk Opportunism combined with the large range of effect it is very effective to mow down enemies in large group. It is best paired with a Tactical Mask.
The Flash grenade explodes instantly upon touching any surface, and blinds everyone in sight for 4 seconds. This grenade is only useful in multiplayer, since enemies in singleplayer are not affected by it in any way. The user theirself however can be blinded by it.
The grenade also affects enemies as well as you and your team mates, which means it can be abused to purposly blind your team mates and annoy them
In order to get the most from the grenade, throw it where you think the enemies will be and quickly look away, since if you are not directly looking at the grenade as it's touching the sourface it will have no effect on you. This under rated grenade can be very useful if used right.
When you are blinded by a flash grenade, you need to fully rely on your radar if you want to live. If the enemy that blinded you goes in for a knife attack, turn around and go back as much as you can, if the enemy is shooting at you, you will be able to see them on the radar and. You can take a risk and charge at them for a knife kill or throw a grenade back at them.
Can lead to the death of an enemy player/team if used right.
A misfire can blind the player himself or his teammates.
