Mission 3: The Shadow

Objectives: Defeat the Circle of Ossus, Protect the Native American Village.

Mission 3, "The Shadow," plunges you into a desperate defensive struggle against the enigmatic Circle of Ossus. This mission demands meticulous planning, robust defenses, and a well-timed counter-attack. You'll begin with a modest base and an allied Native American village that must be protected at all costs. The Circle will launch relentless assaults, testing your ability to manage resources, construct fortifications, and command a diverse army.

Initial Setup & Early Game Strategy

Upon starting, immediately assess your surroundings. Your main base is located to the west, and the allied Native American village (typically Iroquois or Huron, depending on the map variant) is to the east. A small path connects the two. Your initial resources are limited, so prioritize wisely.

  • Resource Gathering: Assign Villagers to gather food from nearby Berry Bushes and hunting animals, and wood from forests. Start mining gold as soon as possible.
  • Defensive Structures:
    • Walls: Immediately begin walling off the northern and eastern approaches to both your base and the Native American village. Focus on creating a continuous defensive perimeter. Pay special attention to the choke point between your base and the village, as this will be a primary attack route.
    • Outposts/Blockhouses: Construct several Outposts (or Blockhouses if playing as British/French) at key defensive positions. Place them behind your walls, particularly at corners and along main attack routes. Aim for 2-3 Outposts protecting your base and another 2-3 for the village. Upgrade them with the "Advanced Outposts" technology from the Town Center as soon as possible for increased range and attack.
  • Unit Production: Start training a small force of Musketeers and Pikemen from your Barracks. Musketeers will be your primary anti-infantry and anti-cavalry unit, while Pikemen are crucial for dealing with enemy cavalry and siege units that might slip through.
  • Home City Shipments: Your first Home City shipment should ideally be 700 Wood or 700 Food to accelerate your defensive construction and initial unit production. Alternatively, consider a unit shipment like 5 Musketeers or 4 Pikemen if you feel immediately threatened.

Defending Against the Waves

The Circle of Ossus will launch a total of five distinct waves of attacks against your settlement. Each wave increases in intensity and unit diversity. It's crucial to understand their composition to counter them effectively.

General Defensive Principles:

  • Choke Points: use the natural terrain and your constructed walls to create choke points where enemy units funnel into a concentrated area, making them vulnerable to your defenses.
  • Unit Positioning: Place Pikemen in front of Musketeers to absorb cavalry charges. Keep Cannons (once available) behind your main line to provide devastating area-of-effect damage.
  • Repairing: Always have a few Villagers on standby to repair damaged walls and defensive structures during and after attacks.
  • Scouting: Periodically send a scout or a lone unit to observe enemy movements and anticipate the direction of the next attack.

Wave Breakdown:

Wave # Approx. Timing (from start) Primary Enemy Units Recommended Counter Notes
Wave 1 ~5-7 minutes Light Infantry (e.g., Crossbowmen, Rodeleros) Musketeers, Outposts Relatively small force, primarily targets the Native American village. Focus your initial Musketeers here.
Wave 2 ~9-11 minutes Heavy Infantry (e.g., Pikemen, Halberdiers), Light Cavalry (e.g., Hussars) Musketeers, Pikemen, Outposts More diverse. Ensure you have a good mix of Musketeers and Pikemen. Cavalry will attempt to bypass walls.
Wave 3 ~13-15 minutes Heavy Infantry, Heavy Cavalry (e.g., Cuirassiers), Mortars/Culverins Musketeers, Pikemen, Cannons (if available), Outposts First appearance of siege units. Prioritize destroying enemy Mortars/Culverins with your own Cannons or a quick cavalry raid.
Wave 4 ~17-19 minutes Mixed Infantry, Cavalry, Artillery (Cannons, Mortars), some Elite Units Balanced Army (Musketeers, Pikemen, Cannons), Home City units Significant force. Expect attacks on both your base and the village simultaneously. Use Home City shipments for reinforcements.
Wave 5 ~21-23 minutes Large, diverse army including Elite Infantry, Cavalry, multiple Artillery pieces, and possibly unique Circle units. Large Balanced Army, multiple Cannons, Home City shipments (especially unit shipments) The most challenging defensive wave. Ensure all your defenses are fully upgraded and you have a strong standing army.

Mid-Game: Building a Balanced Army

While defending, continuously train units and expand your economy. A "balanced army" in this mission means a composition that can effectively counter all enemy unit types. As you progress, your army should evolve:

  • Early Army (Waves 1-2): Primarily 15-20 Musketeers and 8-10 Pikemen.
  • Mid-Game Army (Waves 3-5): Expand to 25-30 Musketeers, 12-15 Pikemen, and begin producing 2-3 Falconets (light cannons). Falconets are excellent for clearing enemy infantry blobs and destroying siege units.
  • Late Game/Counter-Attack Army: Aim for 30-40 Musketeers, 15-20 Pikemen, 4-6 Falconets, and potentially 2 Heavy Cannons for the final push. Consider adding a few Hussars for raiding or flanking maneuvers.

Home City Card Recommendations

Strategic use of Home City cards is vital for success in "The Shadow."

  • Economy & Infrastructure:
    • 700 Wood/Food/Coin: Essential for early resource boosts.
    • Economic Theory/Advanced Market: Boosts resource gathering rates.
    • Factories: If you reach Age IV, a Factory can provide a steady stream of resources or even produce Heavy Cannons.
  • Military & Defense:
    • Musketeer/Pikeman/Hussar Shipments: Direct unit reinforcements are invaluable during heavy defensive waves or for quickly assembling your counter-attack force.
    • Fort: A powerful defensive structure that can turn the tide of a battle, especially if placed near the Native American village.
    • Advanced Arsenal/Guard/Imperial Upgrades: Boosts unit stats and allows for more powerful unit types.
    • Team Combat/Team Cavalry/Team Artillery: If playing with AI allies (though less relevant in single-player campaigns, these can still provide personal buffs).

Counter-Attack: Defeating the Circle of Ossus

After successfully repelling the fifth wave, your objective will shift to destroying the Circle of Ossus's main base. Their base is located to the north-east of the Native American village, heavily fortified with walls, Outposts, and a few defensive units.

  1. Assemble Your Army: Gather your entire standing army. Ensure you have at least 4-6 Cannons (Falconets or Heavy Cannons) for siege. Replenish any lost units and upgrade them to their highest available level.
  2. Advance Cautiously: Move your army towards the Circle's base. Keep your Cannons protected behind your infantry and cavalry.
  3. Siege Warfare:
    • Use your Cannons to systematically destroy the enemy's walls and Outposts. Prioritize structures that are actively firing at your units.
    • Once a breach is made, focus your Cannons on any enemy artillery or concentrated groups of infantry.
  4. Infantry Push: Once defenses are weakened, send in your Musketeers and Pikemen to clear out the remaining enemy units. Use Pikemen to engage any enemy cavalry that attempts to flank your Cannons.
  5. Target Key Structures: The primary targets are the enemy's Barracks, Stables, and Town Center to cripple their unit production. Destroying all enemy military structures and units will complete the mission.

Common Pitfalls & Tips:

  • Neglecting the Native American Village: The village is often the primary target for early waves. Ensure its defenses are as robust as your own base.
  • Over-committing to Offense Too Early: Do not attempt to counter-attack before all five waves are repelled. Your forces will be spread too thin, and your base will be vulnerable.
  • Ignoring Population Limit: Continuously build Houses to maintain your population capacity. Running into the population cap during an attack can be disastrous.
  • Lack of Cannons: The final assault on the Circle's base is significantly harder without sufficient artillery to breach their defenses.
  • Micro-managing Units: During intense waves, pause the game (if playing single-player) to issue precise commands and reposition units for optimal engagement.

By following these detailed strategies and preparing for each wave, you will successfully defend the village and dismantle the Circle of Ossus's presence in "The Shadow."
