This page shows two ordinary encounters in one area and argues which kind should be common. Rules for controls, perception, reinforcement and interruption belong to [Combat Rules](/Hold%20The%20Flood/Combat%20Rules); this page applies them to the player experience. [Build Comparison](/Hold%20The%20Flood/Build%20Comparison) explains the two loadouts used below, and [Hordes and Builds](/Hold%20The%20Flood/Hordes%20and%20Builds) shows the current detailed build examples.

A segment of the long service route: a junction opening onto a straight run of working light, and at its far end a pressure door jammed on its manual bolts. The run is in vacuum. Both encounters below happen here, in one trip.

**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.

All of that is observable from the mouth without fighting anything. The player has no grounds to conclude the alcove is safe for *them* — it is 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 and special abilities triggered by hand, 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.** 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 stays defeated in the current station arrangement, 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 information in its own right, not a reward for combat, and manipulating it is not the experiment.

**Temporary growth.** Under the stage-only growth described in [Combat Rules](/Hold%20The%20Flood/Combat%20Rules), clearing an announced release's committed attackers or sealing their access earns one upgrade choice. Preventing the release before commitment buys safety and access without an upgrade; escape leaves it unresolved. All temporary upgrades end on any return aboard.

**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 living return preserves the arrangement and defeated creatures; surviving creatures can still move in along visible routes. A resolved stage stays spent. Death shifts unconnected areas and resets transient crowds, while selected permanent changes and recorded evidence remain.

**Objective.** Cut the door's jammed bolts and hand-cycle it open with the suit's baseline cutter — the established act on this route.

**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. The ordinary-fire default takes the nearest visible 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 additional Caller or alarm release.

**Decisions, and what they cost.** Resolve the caller/source, present enemies and travelling groups before working, committing the relevant equipment or inputs up front. A separately cued later arrival can still change the situation. Work in bursts between arrivals, using a Cycler shove to displace what arrives and buy stages. Or take what has been done and leave.

The middle option has a price that lasts: taking hits spends condition, with no passive field recovery. It narrows the margin before a damage death for the rest of that expedition, including the walk home. So working under fire is not free just because damage cannot cancel a stage — it borrows against every later margin on the trip.

**Interruption.** The work has named visible stages — each bolt, then each cycle of the door. Leaving before the current stage completes loses that stage and the time and oxygen already spent on it. Completed stages are checkpoints and do not roll back. Damage alone does not cancel the work; an enemy stops it only by a readable physical result, such as forcing the astronaut off the control or occupying it. So withdrawal has a real opportunity cost without permanent loss: the trip that ends here bought fewer stages than it hoped, and the bolts already cut stay cut.
