How to kill secretly in STALKER 2
When performing stealth kills in STALKER 2: Heart of Chernobyl, Skiff's knife is used for more than just chopping boxes and boards. If you find yourself in a situation where you can avoid fighting an entire enemy camp, you can sneak up behind the enemy, whip out your knife, and press the fire button for a stealth kill. Please wait until Skiff raises his knife before attacking, otherwise he will perform a normal knife attack, which has a low chance of directly killing the enemy.
The animation of the knife attack takes some time to execute, so make sure there are no enemies nearby, or that the approaching enemies have their backs to you. Remember, you can pick up the body and hide it so it doesn't alert other enemies. Be aware that this method will not work on mutants like ghosts.
The stealth mechanics in STALKER 2: Heart of Chernobyl can be a bit wonky at times. If there is solid cover between you and the enemy, it shouldn't be difficult for you to avoid their sight. However, if you walk out into an open area and the enemy is facing your general location, there's a good chance they'll spot you. Therefore, stealth kills are most effective in some linear areas, such as the domed underground facilities under "smaller areas".
