If roaming the post-apocalyptic Exclusion Zone wasn’t scary enough in Stalker 2, there are actually invisible enemies that can sneak up on you and cause some serious damage. While you might think that it’s an impossible challenge to take these on, they can in fact be beaten. Here, we’ll go through how to defeat these invisible enemies so you can say goodbye to the worry of being snuck up on ever again. How to kill invisible enemies in Stalker 2 If you’ve come across some invisible enemies in Stalker 2, you’re likely making your way through the There and Back Again mission. In this mission and the open world, there are two different invisible enemies you can come across – the Bloodsucker and the Poltergeist – with each being killable. Tackling the Bloodsucker first, this is definitely the easier of the two to beat since you’ll actually get a clear indication of where they are. Listen out for both their walking noise, especially on grass, as well as any noise emitting from the Bloodsucker itself. They have an almost growl that you can utilize to pinpoint their whereabouts before you get snuck up on, and you can start firing in their direction to get the kill. Additionally, Bloodsuckers do make themselves visible when they attempt to attack you so if you’re looking for a more risky play, you can wait for this, then shoot as fast as possible. As for the Poltergeist, specifically in the There and Back Again mission, you’ll have to wait until near the end to get your kill. When you make your way to the top of the boat to disable the radio, you can utilize the tight area and staircase to both get a glimpse of the Poltergeist as well as getting some shots off. If you do make a connection, it will turn into a pile of rocks, so you know you’ve done some damage. Do this a couple more times, being wary of getting attacked yourself since it is a powerful enemy, and you should be able to defeat it. Try sneaking too and potentially a grenade if you’ve got enough room, just to ensure you’ve got sufficient damage output without being too vulnerable. You’ll know you’ve got the kill because the body of the Poltergeist will be visible! Other Stalker 2 articles you may like Should you play the other Stalker games before playing Stalker 2?
