During a Halo Infinite technical preview livestream that premiered ahead of the first Halo Infinite beta test, 343 Industries Lead Multiplayer Designer Tom French confirmed that assassinations will not be in Halo Infinite at launch, but will eventually make their way into the game at a later date.
Assassinations fancy killmoves that allow players to execute enemies they catch off guard from behind have become a fan-favorite part of the franchise ever since they were introduced in Halo: Reach. However, 343 Industries has chosen to remove them from Halo Infinite for launch because of the fact that they put the player performing the assassination at great risk without any gameplay benefit. Back-smacking, or simply hitting a player in the back with a standard melee, kills them in one hit as well. Therefore, there s really no point to using assassinations.
