Insta-Kill is a versus multiplayer gamemode in Serious Sam HD: The Second Encounter and Serious Sam 3: BFE.


Insta-Kill is a variant of Deathmatch where each player is only equipped with a RAPTOR Sniper Rifle that can kill anyone in one hit, no matter if the gun is zoomed in or not. Otherwise, the rules are the same; kill enough people to reach the kill limit or have enough kills when the time limit is over.

Insta-Kill can be played in any Deathmatch level.


  • Take advantage of the Sniper Rifle's scope to take out enemies at long range. However, don't stand in one location for too long, or people will start to hate you for camping.
  • This game mode is built for those with good reflexes, as the ability to quickly react to and hit enemies is vital because of the one bullet the Sniper Rifle fires and the small delay between shots.
