In the main menu you will find all the instructions to play, survive enough time to build the transmission tower to win the game!
The World
Humanity has collapsed after decades of escalating ecological collapse, industrial toxins, and uncontrolled nuclear spills.
Your Situation
You are the last surviving operator of an emergency shelter—an underground bunker built by a now-defunct Soviet-era research program. You were not meant to stay long, but the world outside deteriorated faster than expected.
Your only hope is the half-destroyed Rescue Beacon hidden in the bunker. If you can repair it and amplify the signal, an orbiting autonomous drone (one of the last operational machines in the sky) may detect it and extract you.
The Threat
The environment itself is your enemy:
Toxic fog eats away at your filters.
Radiation rainfall destroys equipment in minutes.
Black smog induces hunger and thirst spikes.
Dust storms bury scavenging routes under corrosive particles.
No mutants, no raiders—just a dead planet slowly killing you.
The Struggle to Survive
You are surrounded by fragments of the old world:
Broken Soviet tools
Cracked electronics
Damaged chemical barrels
Rusted plates and wires from abandoned air filtration systems
Using these scraps, you rebuild filters, craft purifiers, and slowly restore the ruined shelter piece by piece.
Meanwhile, weather anomalies hit in unpredictable intervals—echoes of a world poisoned beyond repair.
The Goal
Reach Beacon Stage 3.
When the beacon activates, a distress drone might still be listening.
If it is… you escape.
If not… the shelter becomes your tomb like all the others.

Seems like a pretty bad game?
Next to no clue what just about anything does, weather is meaningless because you can't play around it (staying inside doesn't slow decay, scavenge is too long to take advantage of loot etc) even with airlock this doesn't change
Some wires got randomly eaten at some point? Which is a pain because I both needed them and they're hard to get - didn't make anything, they just went away
No clue what base did, water purifier and food synth seemed to do nothing
No faster than when first starting the game, kind of just a waste of time
If these buildable and features actually did something, I would ask for more tooltips - as it is, genuinely not sure they have a function to begin with
Also when you fullscreen the game, the actual game elements don't adjust to the screen size so it stays tiny and you have to zoom your browser
i completed the game, manage to fix the beacon to level 3 by having no idea what it needed. The game isn't bad, but require abit more instruction on what does what and what gets what, throughout the game i am not sure if there is a RNG behind item drop, but i didnt manage to get much chemical and couldnt deduct where it came from, the other parts however is quite obvious on where you get them from, since the drop rate seems to be higher.
so, in general the game need a better instruction on loot, and a better instruction on fixing the beacon, cause i dont think i see any indication on what it needed to fix the thing, and i simply spam on tech till the button appear and fix the beacon.
what expedition gives chems? been playing 30 min and haven't got any ye
Supplies gave chems (never get rare chems), Scrap gave plates for whatever reason, Tech gave wires
