Fast answer
The answer before the background
For a dependable campaign setup, start with one high-value ranged damage tower, one area-damage or artillery option, one defender or stall tool, and one support or specialist card. Long-range damage is the safest general pick for open maps; artillery or splash damage is better when enemies bunch together; defenders are strongest when a stage has a short approach or a dangerous final wave. In Underground Part 2, test Raff Rats when enemy density makes converted enemies valuable, but do not treat it as an automatic replacement for core damage. The best loadout changes with terrain, mission rules, and which cards you have upgraded.
Verified framework
How to judge towers before choosing a deck
Junkworld lets players place towers across the map rather than restricting every card to fixed build points. That makes range, firing angles, coverage, and the ability to relocate between waves central to performance. Ironhide also presents towers, heroes, and tactics as a combined system, so a tower that looks average alone can become excellent when a hero or tactic holds enemies inside its attack zone.
The game is not a passive build-and-watch tower defense title. Battles include a build phase, but heroes, tactic cards, tower skills, and unit movement can all change the result during combat. For that reason, the most useful comparison is not simply damage per second. A strong card should either solve a recurring problem, create time for other cards to work, or remain useful across several terrain types.
- Generalist damage: best for a first clear or an unfamiliar stage.
- Area damage: best when lanes compress enemies into predictable groups.
- Defenders and stall: best when enemies need to be held inside overlapping ranges.
- Support and specialist towers: best when their effect directly answers the mission or terrain.
- Raff Rats: a verified Underground Part 2 tower with an enemy-conversion theme, making it a specialist control choice rather than a confirmed universal carry.
| Role | Best use | Main limitation |
|---|---|---|
| Ranged damage | Open maps, long approaches, and mixed waves | Can struggle when enemies reach it quickly or require crowd control |
| Artillery or splash | Chokepoints, clustered enemies, and multi-lane pressure | Less efficient when targets stay widely separated |
| Defender or stall | Short lanes, late-wave emergencies, and protecting fragile damage cards | Usually contributes less direct damage |
| Support | Buffing a concentrated group and improving a planned kill zone | Needs good placement and enough damage around it |
| Raff Rats | Underground stages where converted enemies can disrupt or thin a push | Specialist value; public sources do not establish it as the best damage tower |

By mode and map
Recommended priorities for common stage types
For ordinary campaign stages, choose consistency over spectacle. A balanced deck gives you an answer to swarms, durable targets, leaks, and emergencies. If the map has several approach routes, favor range and repositioning. If the routes merge, concentrate damage around the merge and use a defender or control card to keep enemies there.
For missions with unusual restrictions, do not automatically bring the same four cards. Junkworld’s mission design can change the value of a tower: a stage that limits building opportunities rewards cards that cover more space, while a stage with traps or tight corridors rewards control and careful timing. The official Underground update specifically adds dangerous enemies and new missions, so older campaign habits may not transfer cleanly to that area.
- Open terrain: use a long-range damage card, then place support so several towers share its benefit. Add one emergency stall option.
- Narrow corridors or junctions: favor splash or artillery damage and place a defender just before the main firing zone.
- Multiple lanes: choose coverage and mobility over a tower that is powerful only from one perfect position.
- Short maps: prioritize immediate control and dependable early damage; expensive specialists may come online too late.
- Boss or elite-heavy stages: keep at least one card that can buy time, because uninterrupted damage is more valuable than a fragile all-in setup.
- Underground Part 2: try Raff Rats when enemy density and conversion opportunities are central to the stage. Keep a reliable damage card beside it until you have confirmed the mission’s enemy pattern.
| Situation | First pick | Second pick | What to avoid |
|---|---|---|---|
| New stage or first clear | Flexible ranged damage | Defender or support | A deck built around one gimmick |
| Crowded waves | Area damage or artillery | Stall or grouping control | Four single-target cards |
| Long open approach | Long-range damage | Support or a second damage source | Short-range cards without protection |
| Underground specialist mission | Raff Rats as a test slot | Reliable damage and emergency control | Assuming the new tower solves every wave |
Place towers where their ranges overlap, but leave room to move units and activate skills. A slightly weaker card with better coverage often outperforms a stronger card placed at the edge of the action.
Progression plan
What to upgrade and when
Early in progression, upgrade the cards that solve the largest number of stages. A dependable damage tower should usually come before a narrow specialist because it helps you earn stars, clear missions, and unlock later options. Pair it with one control or defensive card rather than spending all early resources on several similar attackers.
In the middle of the campaign, build a small rotation instead of trying to max everything. Keep one loadout for open maps, one for compressed lanes, and one experimental slot for new content. This matters because the game’s progression is card-based and the available roster expands through updates. The App Store history confirms that Underground content introduced new towers and missions, while the official site lists 19 towers and allows them to be placed anywhere on the map.
Late progression is where specialist cards become more attractive. Test them against the exact enemy groups and mission rules they are meant to answer. Do not judge a new tower after one failed attempt if the failure came from poor placement, an unsuitable hero, or a mismatch between its role and the map.
- First priority: one broadly useful damage tower and its most valuable upgrades.
- Second priority: one defender, stall, or area-control answer for leaks and swarms.
- Third priority: support or specialist cards that improve a deck you already know how to use.
- After each difficult loss, change one variable at a time so you can identify whether the problem was tower choice, placement, timing, or progression level.
- Save experimental slots for new update content instead of rebuilding your entire deck immediately.
| Progress point | Recommended focus | Reason |
|---|---|---|
| Early campaign | General damage plus basic control | Reliable clears and faster unlock progress |
| Mid campaign | Two terrain-specific loadouts | Maps begin rewarding different ranges and damage patterns |
| Late campaign | Specialists, support, and update towers | Mission rules and enemy combinations matter more than raw flexibility |
| Completion attempts | Fine-tuned placement and skill timing | Small positioning gains can matter more than another unlocked card |
No official source reviewed publishes a complete numerical ranking. If a community list gives a tower an S tier, treat it as a starting hypothesis and test it on your own maps.
Practical setup
A simple four-card method
Before starting a stage, identify the map’s main failure condition. If enemies leak because they arrive too quickly, add control. If they survive too long, add damage or support. If several paths overwhelm one side of the map, choose coverage and mobility. This method is more reliable than selecting four cards because they are individually popular.
During the build phase, place the damage card where it covers the longest useful section of the route, not merely the first visible entrance. Put control where enemies will remain inside that damage range. Keep the support card close enough to affect the main cluster, and avoid spending every resource before you know which lane will become dangerous.
During combat, activate skills for overlap rather than using them as soon as they are ready. Move a tower or hero when the wave changes direction, and reserve one emergency option for a fast enemy or boss push. Because the game emphasizes active defense, timing is part of a tower’s real value.
- One damage card for dependable kills.
- One area or artillery card for groups.
- One defender or stall card for time and leak prevention.
- One support or specialist card, with Raff Rats as the Underground experiment.
- If the stage still fails, replace only the weakest role rather than changing every card at once.
The strongest practical deck is the one that covers the map’s failure condition. Use generalists for progression, specialists for confirmed matchups, and treat every ranking as provisional when official statistics are unavailable.
FAQ
Common questions
Is there one best tower for every Junkworld stage?
No. The game’s free placement, active skills, heroes, tactics, terrain, and mission rules make universal rankings unreliable. A flexible damage tower is the safest starting point, but area control, defenders, or specialists can be better on specific maps.
Is Raff Rats the strongest tower in Underground Part 2?
It is the named tower added with Underground Part 2, and its enemy-conversion identity makes it worth testing there. However, the official announcement does not publish a damage ranking, so it should be treated as a specialist control option rather than a confirmed best tower.
What should new players upgrade first?
Upgrade one broadly useful damage card first, then add a control or defensive answer. This gives you a stable foundation for earning stars and unlocking more cards before investing heavily in narrow specialists.
Should I use the same deck on every map?
Use the same core roles, not necessarily the same cards. Keep dependable damage, control, and emergency coverage, then swap the fourth slot according to terrain, enemy density, lane length, or mission rules.
Why does a supposedly strong tower keep failing for me?
Check placement, range overlap, upgrade timing, hero choice, and skill timing before replacing it. Junkworld is active during waves, so a tower can underperform when enemies leave its range or when its control effect is not synchronized with your main damage zone.
