The bridge announced it the same way it had always announced everything: by offering no announcement at all.
The walls came in. The post spacing tightened. The thermal overlay lit with warm signatures on both sides, not two or three but a continuous band of loaded mechanisms running along the rock face as far as the lock-on could resolve. He had never seen density like this. Every hole loaded. Every position covered. The floor ahead had no cold signatures yet but the character of the section had already told him what it was.
He kept walking.
The first arrows fired from the left wall simultaneously, four of them, aimed across a spread that covered the full centre of the bridge at head and chest height. He was already moving right, the thermal having shown the spike a half-second before the snaps, and three passed through the air he had vacated. The fourth caught the shield on his back with a hard knock, the impact distinct through the torso plate, the arrowhead stopped by the shield material without penetrating. He felt it. He did not slow down.
Right wall: two more, offset from the left sequence. He shifted back left and both passed behind him and buried themselves in the posts across the bridge. He was threading the crossfire without stopping and the bridge was running out of positions to aim from. He walked through the remaining loaded holes and nothing else fired.
Floor: cold band, narrow. He stepped around it without breaking stride.
Second cold band, two metres further, wider. He measured the stride and adjusted and committed his weight to the far side and the panel dropped under his left heel at the instant his weight transferred. The partial release took the heel with it for a fraction of a second and he pitched forward, the vine arm shooting out and catching the railing post ahead, and he pulled himself over the gap and onto solid planking and kept moving. The left shoulder registered the pull. Not the wound tearing. The strain of a joint that had been through too much and was not fully healed. He filed it and kept moving.
The chest was in the path. Cross inside the lid, visible from four metres through the lock-on, the mark clear. He passed it on the right edge of the bridge, tight against the railing, and the floor-level nozzle fired anyway. He had not known about floor-level nozzles. A short pressurised burst from a fitting in the plank surface, aimed at leg height, and it caught his right shin through the gap between the leg armour's lowest segment and his boot. A band of heat across the skin, immediate, sharp. Not as bad as the forearm burn had been. Worse than nothing. He kept walking.
The planks in the next section were wrong in a way the thermal could not show him. He felt the first needle through his left boot sole before he saw it, a small bright puncture that arrived and then began its spreading cold. The needle was not standing proud of the plank — it was flush with the surface, hair-thin, the kind of mechanism that relied on pressure rather than projection. His weight had done the work. He felt the second in his right calf two steps later, above the leg armour's ankle termination, through the skin. The leg armour covered his shin but not the narrow band above the boot line, and something there had been waiting for exactly that gap.
He kept walking, the spread of cold beginning in both sites simultaneously. Different from the first poisoning in character: that had been fast and incapacitating, hitting the hand that triggered it. This was slower, more patient, designed for a moving target. It expected him to keep moving. It was counting on the movement to carry the toxin further.
He pulled the vitality injection from the storage pouch without stopping, bit the cap, got it down. The cold spread to the mid-points of its reach and slowed. He kept walking and it began to retreat, the vitality injection working against it faster than pure endurance would have managed. In four minutes the cold was mostly gone. The puncture sites ached. He kept walking.
Three pivoting posts in sequence, one after the other, the triggers set faster than in any previous section. He blocked the first with the hydraulic arm mid-stride. Blocked the second with the same arm on the backswing. The third fired while the arm was still recovering and caught his left side as he turned to face it, the post's sweep blunter than expected, hitting the torso plate's edge rather than his ribs directly. The plate distributed some of it. Not enough. The impact drove into his left side under the plate's lower edge and something there decided to make itself known. Not a break. A bruise forming in real time. He turned forward and kept walking.
He took stock without stopping.
Right shin: burn, manageable. Left foot sole and right calf: needle punctures, toxin clearing. Left shoulder: strained, not torn. Left ribs: blunt impact, bruising. Vine arm housing: the shield had taken an arrow and was functional. Everything working. Everything damaged.
The section ahead had a different character from what he had walked through. The wall holes were still dense but the floor had a shape he recognised: the sequential pattern of a collapse section, the thermal showing a band of cold signatures running in a line down the bridge's full length. He had run one of these before and lost the scooter to it. He had nothing to lose this time except himself.
He ran.
The first plank dropped at his third stride. He felt it go under his heel, the familiar partial release, and the leg armour carried him through the gap without breaking pace. The second plank went under the heel of his next right stride. Then a stretch of solid surface for four strides — the collapse wave moving slower than he was — and then the floor behind him began dropping in sequence, the sound a continuous low series of separations, each one a fraction of a second after the last. He did not look back. The thermal showed the wave falling away behind him and ahead the floor was still cold-banded but intact.
The shin burn registered with each stride, a specific heat at the impact point that his body was cataloguing and setting aside. He ran through it. The leg armour absorbed the impact load that the burn made him want to protect. The gap opened behind him and he left it there and came out the far side on solid planking and kept going.
The combo setup appeared twenty metres ahead.
He read it in full: post spacing tight, thermal showing a cold band in the floor's centre and two warm holes in both walls at torso height, and one railing post with a different thermal signature at its base, a pivoting post, the mechanism warm from loading. Three threats, coordinated, designed for a person who had learned to handle each one separately and had not yet faced all three at once.
He went left to the railing edge and dropped low, his body angling below torso height as he closed the last ten metres. The arrows fired. Both crossed the air above his shoulders and hit the far side posts. He heard the pivoting post swing through the space a standing person would have occupied, the mechanism completing its arc through nothing. The floor dropped in the centre of the bridge, two metres to his right. He was already past it, his right hand on the railing for one stride, and then back on the planks and walking.
One arrow had clipped the outer housing of the vine arm. He felt it as a jar in the arm rather than a penetration. He flexed the hand, extended a vine, retracted it. Functional.
He kept walking.
The walls began to widen. The post spacing normalised. The thermal showed nothing warm in the walls for forty metres, then sixty, then as far as the lock-on could resolve. The floor showed no cold signatures. The holes that had been in the walls were replaced by bare rock. The dense sequence of the gauntlet was behind him and the bridge ahead was simply the bridge, grey and long and quiet.
He walked until the last of the tight section was clearly behind him. Then he stopped and checked everything.
Shin burn: painful, treatable later. Needle sites: clear, the vitality injection had done its work. Shoulder strain: present, manageable. Left ribs: bruised, moving with his breathing, not stopping his breathing. Vine arm housing: functional. Shield: an arrow lodged in the outer surface, not penetrating, he reached back and pulled it free. The shield had held.
He put the arrow shaft in the storage pouch. Even here, even now, there was no reason to leave it on the planks.
He did not immediately stand up.
He was damaged in seven specific ways and all of them were manageable and none of them had stopped him and the bridge was in front of him with its end somewhere ahead and he was still the person walking toward it.
He kept going.
