Stalker 2's open world always has plenty of chaos to throw at you, but some of its more formidable foes are basically invisible when you first engage with them. Yep, the game's 'Poltergeist' and 'Bloodsucker' enemies come in various invisible forms, but they can be beaten with the right approach.

Stalker 2 Invisible Enemy: Bloodsucker
Bloodsuckers are the more common of these two invisible enemy types, and actually, these ones will fade into view every now and then - which is the perfect time to strike.
Stalker 2's Bloodsuckers will often dart around as they approach you - and if you use our recommended aim assist settings, you should feel your controller pull towards them as they get closer. As that happens, it's worth unloading a few rounds into their invisible bodies - and you should see blood splatters appear when you strike.
However, we found that the best time to take down Bloodsuckers is when they get super close and try to hit you. At this point, if you can effectively dodge them (or quickly move after they hit), you should be able to see their bodies for a few short seconds before they dart off again. Fire as many rounds into them here as possible - preferably with a close-range weapon like an SMG.
If you do this a few times on the game's normal, 'Stalker' difficulty — taking time to heal when needed — you should successfully take down any Bloodsuckers in your way.
Stalker 2 Invisible Enemy: Poltergeist
Poltergeists are the tougher of these two enemy types, and they'll stay invisible throughout an encounter. You'll notice them use random objects around you to inflict damage, and as bait to try and lure you in.
Sound is super important with Poltergeists - crank your volume and listen for their static sound. Eventually, you should see what looks like a dusty orb of energy, which will take damage if you shoot at it.
The best course of action with Stalker 2's Poltergeists is to avoid the objects they summon, and only shoot when you have a good line of sight on the energy orb. These guys can be stubborn, but if you keep repeating this pattern — avoiding their object attacks and getting shots down range when you catch a glimpse of them — you should eventually defeat any poltergeists that stand in your way.
