Look, the Zone isn't supposed to be fair. We all knew that going in. But Stalker 2 Ad Astra Per Aspera is a special kind of "welcome to Chornobyl" that has a lot of players throwing their headsets across the room. It’s one of those main story missions that feels less like a quest and more like an endurance test designed by someone who really hates your stamina bar.
If you're currently knee-deep in radioactive sludge wondering why your brain is melting, you're not alone. This mission is a gauntlet of swamp navigation, psi-fields, and a scripted sequence that is, frankly, kind of mean.
Basically, you’re sent down to the Swamps to find Faust and reclaim your scanner. But the path to the old Clear Sky base is blocked by a massive psi-barrier. To drop it, you have to hunt down four psi-beacons scattered across the worst terrain the game has to offer.
Preparation Is Everything (No, Seriously)
Don't just run in. Seriously.
You’ve probably seen the optional objective to find a suit with high psi-protection. Ignore this at your own peril. You can grab a SEVA-D suit or an Ecologist suit (SSP-99) if you're willing to do a bit of scouting first. Some players find a free Ecologist suit in the train cars just west of the swamp, while others swear by buying a suit from Icarus in Zaton.
If you can't be bothered with a new suit, you need Psi-Block. Stock up on it. You’ll also want a lot of vodka and medkits. The water in the Swamps is irradiated and it slows you down to a crawl. You’re going to be burning through resources just to stay alive while you walk from point A to point B.
One big tip from the community: go light. You’re going to find a ton of loot toward the end of this mission. If you go in carrying 50kg of gear, you’re going to have a miserable time trying to outrun the threats at the end.
The Four Beacons of Misery
You have to deactivate these in the Swamps. The map marks them, but getting to them is the real trick.
- The Old Church: This one is a classic Stalker setup. It’s a giant, crumbling church filled with a Bayun cat mutant. These things are creepy as hell because they mimic human voices to lure you in. Once you kill the cat, you have to break some yellow planks in the pulpit, drop down, and then platform your way up to the attic to find the beacon.
- Burnt Farmstead: This area is a nightmare of fire anomalies. It’s also home to a pack of Blind Dogs. The beacon is at the top of an old watchtower. Use the anomalies to your advantage; if you kite the dogs into the fire, they’ll do the work for you.
- The Pumping Station: This is probably the hardest one because of the Controller. These mutants are the worst. They blast your brain from a distance, making your screen wobble and your health drop. Stay behind cover and peek out to land headshots. The beacon is on the roof tower of the station.
- Second Vanguard: This is further south. The terrain here is just a mess of narrow land strips. If you fall into the deep water, you're dead meat. Climb the ladder on the large tower to find the final beacon.
The Scripted Chaos at Warren Shack
Once the beacons are down, the game decides to turn the heat up. As you head toward the Clear Sky base, you’ll pass through a place called Warren Shack.
Everything goes wrong here.
First, a Chimera spawns. These are arguably the most dangerous mutants in the game. They jump, they hit hard, and they have way too much health. Most players recommend just running. In fact, there is an achievement called "Run, stalker run!" for a reason.
While you’re trying not to get eaten by the Chimera, a scripted Emission begins. The sky turns blood-red, lightning starts hitting everything, and your health starts ticking down. You have to book it to the Clear Sky base and get into the underground shelter.
Honestly, it feels a bit janky. The Chimera often spawns right behind you even if you just checked. Just keep your finger on the sprint button and don't stop for anything.
Meeting Faust and the Aftermath
Inside the base, you’ll get a cutscene with Faust. He’s a central figure in the plot, and this meeting is a huge lore dump. After the dust settles, you'll finally get your Scanner back.
You also get a pretty sweet reward: Faust's unique handgun, the Deadeye.
Don't forget to look for the Journalist Stashes nearby. There is one in a ruined building near the base that contains a Wanderer Suit. It has great resistances and a +8 kg carry weight bonus, which is a godsend after a mission that probably broke most of your current gear.

Stalker 2 Ad Astra Per Aspera is a bridge. It moves you from the mid-game into the deeper mysteries of the Zone. It’s frustrating, it’s muddy, and it’s occasionally unfair—but that’s exactly what Stalker is supposed to be.
Quick Checklist for Survival:
- Pack light: You want maximum stamina for the Chimera run.
- Psi-resistance: Get a SEVA suit or at least 5-10 Psi-Block pills.
- Watch the water: Stick to the grassy patches in the swamp to avoid the movement penalty.
- The RPG trick: There is an RPG-7U hidden in a locked room at the pumping station (break the boards through the window) that makes the Controller fight a lot shorter.
Once you’ve cleared the base and escaped the Swamps, your next step is usually the mission Extreme Simplicity. But before you head there, find a technician. Your armor is likely shredded, and you’ll need every bit of protection for what comes next.
