《最远的边陲》的掠夺者强度随人口和财富增长。一个200人口、有金库的城镇会招来40多个带着攻城槌的掠夺者。没有像样的城墙、箭塔和部队管理，殖民地几分钟就会被踏平。本指南涵盖城墙工程、箭塔摆放、部队管理、疾病控制，以及从木栅栏到石头要塞的完整防御升级路径。
🏰 Wall Engineering: Palisade to Fortress
| Wall Type | 生命值 | Cost/Tile | Raider Protection | When to Build |
|---|---|---|---|---|
| Wooden Palisade | 200 | 2 logs | Blocks melee raiders. Archers shoot through gaps. Battering ram breaks in 4 hits. | Year 1-2: 30+ population |
| Stone Wall | 800 | 3 stone | Blocks all melee. Battering ram needs 16 hits. Immune to fire arrows. | Year 3-4: 80+ population |
| Fortified Stone Wall | 1,500 | 3 stone + 1 iron | Battering ram needs 30 hits. Trebuchet-resistant. Adds cover bonus for defenders on battlements. | Year 5+: 150+ population |
| Gate | 400-1000 | 4 planks + 2 iron | Weakest point. Always the first target. Double-gate design: outer gate → 3-tile corridor → inner gate. | Immediately after walls |
The Double Gate Kill Corridor
建造：外门→3格宽、10格深的通道→内门。通道两侧建<b>Z+1层高的箭塔</b>配上弓箭手。掠夺者突破外门涌入通道时，两侧弓箭手居高临下射击。10格深通道两侧各6个弓箭手，没有一个掠夺者能活着走到内门。
🗼 Tower Placement: The Overwatch System
| 箭塔类型 | 射程 | 驻军 | 最佳摆放 |
|---|---|---|---|
| Watchtower | 40 tiles | 3 archers | Every 30 tiles along the outer wall. Provides overlapping coverage — each wall section covered by 2 towers. |
| Stone Tower | 50 tiles | 5 archers | Corners of the wall. Covers two wall sections simultaneously. Also flanking the gate corridor. |
| Fortified Tower | 60 tiles | 8 soldiers (archers or crossbowmen) | Critical chokepoint coverage. 1 per every 2 stone towers. Place at the gatehouse and at wall corners facing the expected raid direction. |
Tower Spacing Rule
箭塔必须有<b>重叠的火力覆盖范围</b>。如果A塔射程40、B塔射程40，两塔间距不超过35格。这确保每个靠近城墙的掠夺者始终处于至少两座塔的射程内。面对重甲掠夺者，单塔火力不够。
⚔️ Troop Composition & Management
| 单位 | 装备 | 定位 | 克制 | 人口比例 |
|---|---|---|---|---|
| 🏹 Archer | Bow + Leather Armor | Ranged DPS from towers | Light armor, unshielded raiders | 1 per 15 pop |
| 🏹 Crossbowman | Crossbow + Chainmail | Heavy ranged, armor-piercing | Heavy armor, shielded raiders, battering ram crews | 1 per 25 pop |
| ⚔️ Soldier | Sword + Shield + Plate Armor | Frontline melee | Any raiders that breach the wall | 2 per 50 pop (minimum 4) |
| 🛡️ Spearman | Spear + Shield + Chainmail | Anti-cavalry, gate defense | Mounted raiders, battering rams | Situational (see mounted raids) |
Garrison Rotation
保持<b>50%弓箭手常驻箭塔</b>，另外50%正常劳动。袭击号角响起时暂停，选中所有可驻防殖民者点附近箭塔驻防。200人口城镇应30秒内就绪13个弓箭手。反复演练——城墙上5个还是13个弓箭手的差别，就是守住还是丢城门的差别。
🦠 Disease Control & Sanitation
| 疾病 | 成因 | 致死率 | 预防 |
|---|---|---|---|
| Dysentery | Contaminated water. Well within 10 tiles of outhouse or animal pen. | 10-30% | Place wells 20+ tiles from waste sources. Upgrade outhouses to latrines by year 2. |
| Plague | Rat infestation in granaries and root cellars. | 30-60% | Build rat catchers near all food storage. Keep 200+ medicine stockpiled. Quarantine infected colonists in hospital. |
| Scurvy | No fruit/vegetable food group for 2+ months. | 5-15% | Diversify food: always have 1 vegetable crop + 1 fruit orchard active. Sauerkraut provides vitamin C. |
| Tetanus | Untreated wounds. Dirty hospital. | 5-10% | Stock medicine (1 per colonist). Build hospital with 2+ beds by year 2. Assign a dedicated doctor (priority 2). |
Plague Can Wipe a Colony
瘟疫是游戏里最危险的事件，通过近距离接触在殖民者间传播。<b>紧急处理：</b>暂停。建隔离医院（独立建筑，离城镇15+格）。感染者全移过去。健康者移到城镇另一边。用药治疗。烧掉被污染的食物。瘟疫通过食物供应链传播——市场有感染食物=所有人中招。
FAQ
什么时候建第一道城墙？+
第二年，人口到 50。先用木栅栏围住核心建筑（粮仓、仓库、市场、根窖）。第四年扩建成石墙。
需要多少兵力？+
10% 的人口处于可驻防状态。200 人的城镇需要 20 个弓箭手/弩手 + 4 个士兵。在军械库为所有人备好武器和盔甲——没装备的士兵比没有士兵更糟。
攻城槌怎么对付？+
城门两侧箭塔上放弩手。弩箭可以破甲——4 个弩手能在城门被撞破前干掉攻城槌的操作组。另外：把城门建在坡上——攻城槌上坡速度慢，弓箭手多出 40% 的射击时间。
