Campaign Walkthrough#

Total War: ROME II is not a linear game with fixed chapters and an ending, but a sandbox grand-strategy campaign starting in 272 BC, running roughly 300 years with no time-limit victory condition. So “walkthrough” here isn’t a single main line you finish — it’s a progression route from turn one to meeting a victory condition: how to secure the opening, whom to attack in the first expansion, how to juggle internal affairs and multi-front war at mid-game, and how to push one of the three victory routes to completion late.

This guide follows the campaign’s chronological order, paired with per-faction opening directions and fixes for common sticking points. Turn-count targets are editor experience, not official data.

1. The Opening Decision: How This Campaign Will Be Played#

Before clicking “Start Campaign,” the first step of the walkthrough is actually picking the right faction and reading its victory route. The official manual defines three victory routes — Military, Cultural, and Economic — each with faction-specific conditions, all checkable in the campaign’s “Campaign Objectives” panel:

Take Rome’s military victory as the example. The officially published requirements: fully control the six provinces of Italia, Magna Graecia, Aquitania, Armenia, Africa, and Britannia, hold 140 settlements, and maintain 140 land units and 40 naval units (source: gamepressure.com). That list is itself a ready-made roadmap. Note the official standard names only these three routes — there are no “conquest victory” or “domination victory” variants.

2. The Founding Period: Your First Complete Province#

The opening move is not an expedition — it’s completing your home province first. A province consists of several regions sharing a province panel; only after fully controlling a province can you fully exploit province-level buildings and Edicts, and centrally plan food and public order.

The founding period’s operating rhythm, roughly (editor experience):

One key judgment is vassalize or occupy. Taking a weak state you can’t directly manage as a vassal buys tribute income and a strategic buffer; orderly, culturally similar regions can be occupied and digested directly. The decision criteria are in the Diplomacy chapter.

3. The First Expansion: Whom to Attack First#

After the founding period, the walkthrough enters its first real expansion. The most important rule now is only open one front — every additional front adds an enemy you must face head-on, and multi-front war is the most common starting point of campaign collapse.

Choosing the first target weighs three factors: whether the opponent is weaker than you, whether the area holds key resource points, and whether taking it forms a natural barrier. For Rome, step one is unifying the Italian peninsula (opening fact: at war with the Etruscan League from the start, per gamepressure.com), then extending influence toward southern Italy and Sicily; other factions’ opening directions are in the faction table below.

4. The Internal Loop: Food, Order, and Finance#

Progression is, in essence, gated by three internal metrics: food, public order, and finance. Together they decide whether you can keep expanding:

• Food must stay in surplus; negative food directly drags down public order and reinforcement, a hard ceiling on expansion;
• Public order collapse triggers rebellions in provinces, forcing precious armies home and breaking expansion rhythm;
• Finance’s per-turn net income decides how many forces you can maintain; sustained deficits force disbanding or new taxes.

The full economic framework is broken down in the Economy chapter.

5. Mid-Game: Multi-Front War and Logistics#

Once your territory covers more than two complete provinces, the walkthrough enters the mid-game. The difficulty now isn’t single battles but managing the rear and the front simultaneously:

1. Advance only one main front at a time, stabilizing the other side with non-aggression pacts, trade agreements, or suitable tribute — the cost of collapsing on two fronts far exceeds the price of buying peace;
2. Confirm enemy relief-army movements before sieges — if relief is close, destroy it before besieging, or keep a mobile force watching the perimeter to avoid pincers;
3. Forced river crossings are taboo: crossing troops are easily cut off with their rear exposed to missile fire. Confirm ford and shallow positions before attacking, and use mobile units to draw fire where needed.

6. Resource Points and Progression Decisions#

As territory grows, you’ll meet strategic resources on the campaign map — iron, horses, marble, olives, and more. They’re not just income; they decide whether your late-game unit routes unlock:

Exact resource distributions and output values have no verifiable public data here — the in-game campaign map is authoritative. On your expansion route, put the resource points matching your unit routes at the front of the queue — they directly shape your mid-late-game army.

7. Per-Faction Opening Directions#

Each faction’s founding period plays differently. The table lists the launch-playable factions’ opening priorities (based on the Emperor Edition; directions combine editor experience with verifiable opening facts):

Each faction’s opening situation (neighbor relations, initial wars) changes with patches and DLC — the game is authoritative; finer faction positioning is in the Factions and Campaign Guide chapters.

8. Where Generals Fit in the Walkthrough#

General development spans the whole campaign. Generals’ skills split into campaign and battle tracks (the exact skill entries defer to the in-game trees); the progression principles:

Don’t expect one fixed build template to fit every campaign — assigning tracks by legion purpose beats copying any guide’s “optimal build.”

9. Auto-Resolve vs Manual Battles#

Your walkthrough’s pace depends largely on when you fight manually and when you auto-resolve. Qualitative criteria:

• Clearly superior numbers and unit quality: auto-resolve safely, saving substantial time;
• Evenly matched or disadvantaged: fight manually, using terrain, flanks, and formations to cut losses;
• Sieges and fighting outnumbered: prioritize manual command; auto-resolved casualties are usually higher;
• Grand-strategy pace first: when several small battles stack up, auto-resolve the low-risk ones and save energy for the key set-piece.

The game publishes no auto-resolve win-rate or casualty formulas — outcomes defer to the battle result.

10. Late Game: Pushing the Victory Condition Home#

When territory spans multiple complete provinces and your armies are formed, the walkthrough enters its closing phase — pushing the chosen victory route to completion. For Rome’s military victory, the official six provinces (Italia, Magna Graecia, Aquitania, Armenia, Africa, Britannia) plus 140 settlements, 140 land units, and 40 naval units are the closing checklist (source: gamepressure.com).

A full army is 20 units (including the general’s unit); a late-game Roman-style reference composition (editor experience; units defer to the in-game recruitment panel):

The closing phase still obeys the “one front only” discipline: concentrate main forces on the direction your victory condition demands, stabilize other directions with diplomacy or vassals, and don’t let the rear catch fire just as the condition is met. Meeting a victory condition doesn’t force the campaign to end — players chasing the other two routes can keep playing the same campaign.
