Quick answer: Try an Archer Tower, a Militia Barracks, and a Mage Tower around Southport’s opening bend. Put the soldiers where both attacking towers can cover them. The listed base costs total 240 gold, leaving 25 of the stage’s 265 starting gold. Wait for the tutorial to unlock Reinforcements before relying on them, and avoid calling overlapping waves while learning. This is a researched opening suggestion, not a strategy independently reproduced in gameplay. Check the displayed prices before building. (wikily.gg)
1. Check the game, mode, and starting conditions
This guide targets the original Kingdom Rush, Steam/Windows edition, Southport, Campaign mode, Casual difficulty. It does not cover Kingdom Rush Battles or another sequel. Ironhide’s official strategy page lists Southport’s Campaign, Heroic, and Iron walkthroughs separately; choosing the right mode matters. (kingdomrush.com)
The plan assumes no previously purchased star upgrades and does not depend on a hero. It also uses no consumable items. “Without paid extras” does not mean that acquiring the Steam game is free: the official store lists it as a purchase, with its heroes included at no additional cost. (store.steampowered.com)
Version limitation: Sources were checked on October 6, 2026, but the installed Steam build was not inspected or played. The precise current build number and its behavior have not been independently verified. Treat the instructions below as a source-informed plan, not a tested current-build walkthrough.
Before starting, check these things on your screen:
- The stage name is Southport.
- The selected mode is Campaign and the difficulty is Casual.
- Your starting gold and tower prices match the budget below.
- You have not carried later progression upgrades into this attempt.
Southport’s stage reference lists seven campaign waves and locks the second-tier tower upgrades. Therefore, this opening uses basic towers rather than telling you to upgrade an Archer into a Marksman during the tutorial. (wikily.gg)
2. Choose a shared fighting position around the bend
Look at the road before choosing towers. Ironhide’s Southport map image shows a prominent bend on the left side of the battlefield. Use that bend as your opening reference rather than scattering buildings near every visible destination. (kingdomrush.com)
The proposed layout has three jobs:
- Archer: attack enemies traveling through the bend.
- Barracks: hold enemies at a chosen point.
- Mage: support that same fight, particularly when armored orcs arrive.
A published firsthand Southport demonstration also uses an Archer on the tutorial’s recommended plot, with Barracks and a Mage on the other side. That provides evidence for the combination, but it does not establish that this article’s precise placement has been tested on the current Steam build. (levelwinner.com)
For this plan, call the place where your soldiers stand the holding point. It should be on the road, inside the attack coverage of both ranged towers.
Do not confuse the Barracks building with the soldiers’ position. The rally-point control lets you adjust where the soldiers defend within its permitted area. The tutorial’s troop-command instructions describe this distinction. (kingdomrush.game-waza.net)
Before launching the wave, select each attacking tower and inspect its range. Ask:
- Can it attack enemies approaching the soldiers?
- Can it still attack enemies stopped by the soldiers?
- Is there some covered road beyond the soldiers if an enemy slips through?
Favor a position that answers all three, rather than one that merely looks central.
3. Build the opening in five steps
Suggested opening—not independently gameplay-tested:
- Complete the introductory instructions. Keep the first wave unstarted while you plan.
- Build an Archer on the tutorial-recommended plot beside the bend. Use the visible range indicator to confirm useful road coverage.
- Build a Militia Barracks on a nearby plot. Choose one whose permitted rally area reaches the road covered by the Archer.
- Build a Mage on another nearby plot. Check that its range includes the intended holding point, not just an unrelated stretch of road.
- Set the soldiers’ rally point and start the wave. Watch the first engagement before deciding where the next tower belongs.
The purpose is to make the buildings support one another. An isolated Barracks may stop enemies, but this plan specifically seeks to stop them where your attacking towers can contribute.
Worked opening budget
The tower references list these base construction prices:
| Purchase | Gold |
|---|---|
| Archer Tower | 70 |
| Militia Barracks | 70 |
| Mage Tower | 100 |
| Total spent | 240 |
| Remaining from 265 | 25 |
The costs come from the individual tower references; confirm them against your construction menu, especially if replaying with progression upgrades. (wikily.gg)
The arithmetic is straightforward: 265 − 70 − 70 − 100 = 25.
That remainder is not enough for another basic Archer or Barracks at the listed prices. Do not plan an immediate fourth building without accounting for additional gold earned during the fight.
Also, do not interpret a small remainder as a reason to spend indiscriminately. Your first useful observation is whether the three buildings are actually fighting together.
4. Use a downstream holding point if the first position feels cramped
An alternative is to place the Barracks so that its soldiers defend slightly farther along the road, while retaining the Archer near the bend. Put the Mage where it can cover this downstream holding point.
This is an untested placement alternative, not a second proven solution. Its intended benefit is easier observation: enemies approach through the Archer’s coverage, then reach the soldiers and supporting Mage.
Use it only if the on-screen range and rally indicators confirm the overlap. Moving the soldiers farther along the road is not automatically better.
Compare the alternatives using practical questions:
| Placement choice | What to check |
|---|---|
| Holding point close to the bend | Do both attacking towers cover the soldiers? |
| Holding point farther downstream | Is there still covered road after the soldiers? |
| Mage nearer the approach | Does it continue contributing during the main fight? |
| Mage nearer the soldiers | Does it begin firing early enough to help? |
Keep the comparison fair. Change one placement at a time and avoid simultaneously changing wave timing, upgrades, and hero involvement. Otherwise, you will not know which change affected the attempt.
Ironhide offers a separate Southport Campaign walkthrough on its strategy page if you want a visual reference. Do not assume its linked walkthrough uses your exact platform, build, or difficulty. (kingdomrush.com)
5. Make decisions when the enemy mix changes
Rather than following an invented second-by-second script, use the enemy introductions and wave previews as decision points.
The published Casual walkthrough describes an opening of goblins, followed by the first orc in wave four, more orcs in wave five, a mixed sixth wave, and a goblin-heavy final wave. The stage reference corroborates that sequence. (kingdomrush.game-waza.net)
Use this observation checklist:
During the early goblin waves:
Watch whether enemies stop where you intended. If a tower rarely fires, inspect its coverage before adding another building elsewhere.
When the first orc arrives:
Watch how long your soldiers hold it and whether the Mage participates. The tutorial describes orcs as lightly armored; its armor explanation says armor protects against non-magical attacks. That makes Mage support a sensible choice, rather than assuming more arrows solve every problem. (kingdomrush.game-waza.net)
When several enemies reach the soldiers together:
Identify the failure. Are soldiers falling before supporting fire finishes the enemies, or are enemies escaping while soldiers remain occupied?
For this proposed plan, consider another nearby attacking tower for the first problem, or additional blocking coverage for the second. These are diagnostic suggestions, not verified optimal purchases.
Before calling another wave:
Check that your main position is stable. Early calls offer bonus gold, but the firsthand gameplay guide also describes the risk of overlapping enemies. For a first attempt, prioritize understanding the fight over maximizing that bonus. (levelwinner.com)
6. Time Reinforcements and Rain of Fire around actual threats
Do not build your opening around abilities that are still locked. Southport’s tutorial unlocks Call Reinforcements at wave three and Rain of Fire at the final wave. (wikily.gg)
Once Reinforcements become available, try this sequence:
- Identify the approaching group that needs delaying.
- Select Reinforcements.
- Place them on the road ahead of that group, within supporting tower coverage.
- Watch whether the placement helps the main position or leaves them fighting alone.
A useful reason to deploy them is a developing gap in your blocking line. Another is an enemy that has passed the soldiers but remains within tower range.
Avoid placing them behind a moving enemy and expecting interception. Judge their position relative to the enemy’s direction of travel.
For Rain of Fire, the tutorial emphasizes an emergency or a strong opportunity because of its long cooldown. On the final wave, consider using it when enemies gather at your holding point, rather than immediately spending it on the first isolated goblin. (kingdomrush.game-waza.net)
Watch the ability icons, not an assumed timer. Availability is more important than memorizing a cooldown that has not been checked on your installed build.
7. Recover by fixing one visible problem
If an enemy gets through, resist rebuilding everything at once.
Use this troubleshooting order:
- Check the rally point. Were the soldiers standing where both attacking towers could help?
- Check the Mage. Was it contributing when the orcs reached the fight?
- Check wave timing. Did you introduce another group before the current one was controlled?
- Check Reinforcements. Were they unavailable, misplaced, or simply unused?
- Check the next purchase. Would it address the observed problem, or just fill an empty plot?
Do not save gold for a second-tier upgrade that Southport’s campaign restrictions do not permit. Likewise, avoid repeatedly selling and rebuilding during combat without checking the displayed refund: the tower references distinguish full pre-wave refunds from reduced refunds after battle begins. (wikily.gg)
If you restart, change one thing: move the holding point, reposition the Mage, or stop calling waves early. Record what happened before making another change.
The aim of this opening is not to promise a perfect result. It is to give you a readable first defense: attacking towers cover the same fight, soldiers delay enemies there, and abilities respond to visible threats. Nothing in the plan requires purchasing an extra hero; Steam’s official listing already includes the game’s heroes without an additional charge. (store.steampowered.com)
