KOS Explained Simply

/wp:heading
wp:paragraph

KOS is short for “Kill On Sight.” It’s when someone blasts another player the moment they see them. No “hello,” no teamwork—just straight to battle.

/wp:paragraph
wp:paragraph

You’ll see this often in games where fighting other players is a big deal, like survival adventures or PvP zones.

Where Did KOS Come From

/wp:image
wp:paragraph

The idea of striking first has been around since multiplayer games began.

/wp:paragraph
wp:paragraph

But “Kill On Sight” really took off in the 2000s and 2010s with games that never end, like survival hits.

/wp:paragraph
wp:paragraph

Take DayZ, which started as an ARMA 2 mod in 2013. In that game, you had to figure out fast: trust a stranger or take them down.

/wp:paragraph
wp:paragraph

That’s when KOS became a buzzword for players who attack everyone and a heads-up for risky spots.
