Killstreaks

Killstreaks (abbreviated as ks) is an act of getting a number of kills consecutively without dying. Performing this with 3, 5, and 7 killstreaks will often give you kit upgrades (not applying to Mercy.)

Here is all of the messages each killstreak provides you with additional notes.

Gender Neutrality Controversy
Due to the fact that the 7 and 10 killstreaks say "He's untouchable!" and "He's going HAM!!!", female players have asked for that message to be changed to more gender-neutral versions, like "They" or " ".

This suggestion has never been implemented to the game, as of August 6, 2016.

Kits
These are the upgrades kits get until a player dies. (Exception: Flash/Commando/Ninja 7 killstreaks.) Commando and Spider's effects could still occur for teammates even if they have died. (Teammate gets 7ks boost, dies, but still has it.)

Flash speed boost does not re-occur (unlike Commando/Spider 7ks)

Gravity Cannons will be taken upon death. (Similar to Flash 7ks)
