**Status.** A working encounter proposal after focused review; its frequency and quality remain unvalidated. It shows two ordinary encounters in one proposed area and argues which kind should be common. Example fiction is labelled. Rules for controls, perception, reinforcement and interruption belong to [Combat Rules](/Hold%20The%20Flood/Combat%20Rules); this article applies them to the player experience. No enemy roster, campaign map or balance figure is proposed, and nothing here establishes that any of it is enjoyable.

**What the player sees before committing.** From the junction mouth the whole run is visible and lit. The crowd's spread is readable: thick across the middle, thinner along the left wall. And halfway down there is an alcove that ordinary enemies path around — none enters it, and none is standing in it.

That is the whole of what can be observed, and it is observable from the mouth without fighting anything. Why they avoid it is not established, and the player has no grounds to conclude it is safe for *them* — an anomaly worth recording and testing, not a proven refuge.

**Decisions.** Push the middle, where the crowd is densest and a cascade has most to work with. Move along the thin wall, trading damage for exposure and timing. Or back out and take a branch route, which costs oxygen and time and is a legitimate answer, not a failure. With ordinary fire mostly automatic, these are positioning and timing choices: the run is crossed by deciding where to be and when to spend a special, not by landing individual shots.

**With the Relay Cascade Array.** Ordinary fire is mostly automatic and special abilities are triggered by hand (owner requirement), so the player's decisions here are where to stand, which way to press, and when to spend a special — not whether each shot connects. Density is the Array's best case: moving into the packed middle puts its automatic output where the chain has most to branch through, and the run empties. That is simply a win: the run's crowd is gone for this expedition, and the player has bought the direct route and the oxygen they would have spent going around. No replacement wave arrives and no compensating elite appears. A build that trivialises an ordinary crowd is the point of having built it.

What it does not buy is a quiet door. The run up to the door vestibule is this encounter's boundary; clearing it does not defeat the caller beyond, or consume groups in connected spaces. Nor does "clear" mean sealed: something living outside can later walk in along a real route, cued by sight, sound or door movement along that connected route. It does not spawn as a penalty for clearing the crowd.

**The two rigs spend differently, and neither is simply cheaper.** The Array's modules occupy capacity while carried but are not consumed per use. Keeping or changing that loadout commits space; equipment can still be acquired, removed or left during an expedition under the build rules. The Cycler keeps capacity flexible but spends chosen salvage each time, so its lane costs colony-bound material during the trip. Which is dearer depends on what is scarce that expedition.

**Why fight rather than pass.** The intended payoff is seeing an assembled rig clear the crowd and win direct access. The alcove is also visible to someone who slips past; noticing it does not require a fight. Enemy behaviour is legitimate information; it is not a reward for combat, and manipulating it is not the experiment.

**Withdrawal.** The player can attempt to reach the junction past occupants and pursuers. Enemies continue pursuing while they perceive the astronaut, then search and settle after losing the cue. Withdrawal spends time and oxygen and may defer the objective.

**On return.** A later expedition may change population and density. Deliberate persistent changes and recorded evidence follow the exploration rules; the earlier clearance is not a guarantee for a new expedition.

**The pressure is caused, not scheduled.** Nothing escalates because the player is doing something interesting. The door grinds, and grinding is a physical event ordinary enemies come to look at. This example also holds one caller — an ordinary enemy that, allowed to finish its warning, brings a group from the adjacent space. Before committing to the first bolt the player can see or hear it, recognise its warning behaviour, and see the connected entrance it would summon from. Dealing with it first is a real priority decision with a readable consequence. Ordinary fire takes the nearest valid target, so reaching the caller with it means positioning until nothing else qualifies first — which may mean clearing what stands between. The alternative is spending a manual special to stop the warning in time. That is the choice: rearrange yourself, or spend something. The run in encounter one has no such source.
