INT. UNDERGROUND HALLWAY – NIGHT
The group moves cautiously, weapons raised. Water splashes underfoot. Mist curls along the jagged walls.
VINCENT
Keep your eyes open. Stay in pairs.
MIKEY
(stopping)
I don't know about you guys, but I've never been in a dungeon that feels alive.
CARLA
It's alive because it wants you dead.
Dima's men grunt, keeping pace behind Vincent.
Suddenly, the ground shakes slightly. A low rumble echoes.
DIMA
(in Russian, subtitled)
It's not a quake. Something's moving.
INT. CROSSROAD CHAMBER – NIGHT
They reach a junction. Three tunnels lead in different directions. Symbols on the walls pulse faintly, the red glow waxing and waning.
CARLA
The sigils… they're pointing somewhere.
She traces them with her flashlight. It leads toward the middle tunnel, which seems narrower and darker than the rest.
VINCENT
Middle it is. Stay tight.
Mikey fumbles with his gun.
MIKEY
Tight. Sure. Tight like the noose on my neck?
DIMA
Stop talking. Move.
INT. NARROW TUNNEL – CONTINUOUS
The corridor twists unnaturally. The walls appear to breathe, expanding and contracting. The air grows thicker.
CARLA
(whispering)
This place… it reacts to us.
Suddenly, a loud, wet screech echoes. A massive shadow darts along the ceiling.
MIKEY
I hate this place. I hate this place!
From above, a multi-limbed, spider-like creature drops down — clawed arms snapping toward the group.
VINCENT
Form up! Don't let it separate us!
INTENSE COMBAT – NIGHT
Gunfire lights up the tunnel. Bullets hit the creature, but its thick, chitinous skin barely dents.
CARLA
Shoot the joints! Aim for the joints!
Mikey sprays wildly. One of Dima's men is swiped away, screaming. Vincent shoves Mikey aside just in time.
VINCENT
Mikey! Cover the flank!
The creature leaps at Carla — she ducks, rolls, fires point-blank. It shrieks and scuttles back, wounded but alive.
DIMA
(admiringly)
Not bad.
They realize that coordinated effort is the only way to survive.
AFTERMATH – TUNNEL CORRIDOR
The creature retreats into darkness. The group catches their breath, bruised and soaked.
VINCENT
No more lone heroics. We survive as one unit or not at all.
MIKEY
(half-joking, terrified)
Great. I like everyone equally now.
DIMA
Reluctantly.
Carla examines the walls.
CARLA
The sigils… they move with the monsters. If we follow them, we might find a way out… or straight into another trap.
VINCENT
Then we follow. Carefully.
INT. CRYSTAL-LIT CHAMBER – NIGHT
They enter a massive chamber. stalactites drip black water, and glowing crystals illuminate ancient glyphs on the floor.
At the center: a pulsing red portal, swirling with energy. The group freezes.
MIKEY
Portal. Great. Because that's normal.
CARLA
It's a gateway. To where, I don't know. But it's active.
VINCENT
We don't go near it. We observe.
Suddenly, faint whispers echo — unintelligible, seductive. The group instinctively huddles together.
DIMA
Whispers? In my experience, whispers mean death.
CLOSE ON – RED PORTAL
The portal shimmers, revealing glimpses of otherworldly landscapes, monsters hunting, twisted corridors — glimpses of the dungeon's deeper layers.
CARLA
(terrified)
We're not alone. Others have been trapped here… and they didn't make it.
Vincent studies the portal, his jaw tight.
VINCENT
Then we learn fast. Or we die here too.
EXTREME CLOSE-UP – MIKEY
He swallows hard, voice shaking.
MIKEY
I didn't sign up for this…
VINCENT
No one signs up for this. You survive anyway.
They take another step forward — together, the first time fully united against the dungeon.
INT. TUNNEL – NIGHT
The camera pulls back. The corridor stretches endlessly, walls pulsating. Behind the group, a shadow moves just out of sight, observing, calculating.
The dungeon lives. And it has just begun to hunt.
FADE OUT.
