- Untitled Defense best units are judged by damage, range, upgrade value, and wave consistency.
- S-tier picks carry late waves, bosses like Chained Boss and Confinement, and primary positions.
- Upgrade priority matters: strengthening existing defenses beats spamming low-level units.
- Match your picks to enemies: speed threats need overlapping coverage, tanks need sustained damage.
- Check updates: balance patches can shift which units stay on top.
How We Rank the Best Units in Untitled Defense
Picking the best units in Untitled Defense is less about one overpowered tower and more about how a defensive option performs across the whole match. Units are evaluated on five criteria: reliable damage output, attack range and coverage, upgrade efficiency, consistency against tougher zombie waves, and sustained performance against bosses.
The strongest setups usually combine a core of high-value upgraded units with supporting coverage that fills gaps in the route. Unit value also changes with context — an option that clears opening waves easily can fall off hard once Golden Zombies, Tank Zombies, and bosses start appearing.
| Criteria | What It Measures | Why It Matters |
|---|---|---|
| Damage output | Consistent damage per wave | Determines whether tough enemies die before reaching your base |
| Range | Effective attack coverage | Longer range means more time on target per enemy |
| Upgrade value | Improvement per resource spent | Efficient upgrades outperform massing low-level units |
| Wave consistency | Performance as enemy health rises | Early-game units often fall off in late waves |
| Boss performance | Sustained damage under pressure | Bosses like Confinement require long damage windows |
Treat any tier list as a snapshot. Untitled Defense receives balance changes through official update logs, so re-check your upgrade priorities after each patch — a nerfed core unit can change your entire build.
Untitled Defense Unit Tier List
This tier list organizes defensive units by their practical usefulness across a full match, based on the roles and balance documented in official update information. Because individual unit stats shift with patches, tiers focus on reliability and role rather than fixed numbers.
| Tier | Label | Role | Best For |
|---|---|---|---|
| S | Core Defense | Consistently strong damage or utility, valuable after multiple upgrades | Late waves, bosses, primary positions |
| A | Strong Defense | Reliable overall, depends more on positioning and upgrades | General wave clearing, supporting cores |
| B | Situational Defense | Performs well in specific scenarios only | Early-to-mid coverage, specialized spots |
| C | Early Defense | Helps establish initial defense, fades later | Opening waves, temporary coverage |
S-Tier: Core Defense
- Highest sustained damage
- Strong upgrade scaling
- Boss-wave reliable
- Place at high-traffic positions
A-Tier: Strong Defense
- Reliable wave clearing
- Good range coverage
- Needs proper placement
- Excellent support role
B-Tier: Situational
- Niche effectiveness
- Useful vs specific enemy types
- Mid-game value
- Replace when pressure rises
C-Tier: Early Defense
- Cheap opening coverage
- Fades vs Tank Zombies
- Temporary stopping power
- Sell or phase out later
Do not judge a unit only by how easily it clears early zombies. Waves scale significantly, and a defense that looks comfortable on wave 5 can collapse when Golden and Tank Zombies arrive.
Matching Units to Enemy Types
The best unit choices depend heavily on which enemies are pressuring your route. Untitled Defense mixes zombies, bots, and bosses, each punishing a different defensive weakness.
| Enemy | Category | Threat | Best Unit Response |
|---|---|---|---|
| Basic Zombie | Zombie | Standard | Baseline test — any stable coverage handles these |
| Fast Zombie | Zombie | Speed | Overlapping attack zones from A/S-tier units |
| Ghost | Zombie | Special | Mixed unit types; avoid single-strategy defenses |
| Golden Zombie | Zombie | Durability | Concentrate strongest damage sources on it |
| Tank Zombie | Zombie | High Health | Sustained upgraded damage, not early-game units |
| Chained Boss | Boss | Boss | Pre-upgraded core positions with long range |
| Turbot | Bot | Speed | Multi-position coverage so it can't slip through |
| DynaBot | Bot | Special | Distributed damage across route sections |
| Confinement | Boss | Boss | Fully upgraded cores plus reserve resources |
Fast enemies punish gaps; tanky enemies punish low damage. Identify which threat type is currently leaking through, then adjust your unit mix and upgrade priorities around that specific weakness.
Step-by-Step: Building the Best Unit Setup
Follow this build order to get the most value out of your units from the first wave to the final boss.
Establish Early Coverage
Start with enough low-cost defense to handle Basic Zombies without overspending. Keep a resource reserve so you can react as pressure increases.
Create Overlapping Zones
Position units so multiple towers attack the same route section. This is the single most important counter to Fast Zombies and Turbots.
Upgrade Before Expanding
Once basic coverage is secure, pour resources into your best existing units instead of filling every slot with low-level options. Upgraded cores outperform scattered weak units.
Save for Tough Waves
Hold a reserve for Tank Zombies, Golden Zombies, and stronger bots. Being able to upgrade instantly when a hard wave hits is often the difference between surviving and collapsing.
Pre-Boss Reinforcement
Before Chained Boss or Confinement arrives, max out your strongest damage positions, especially spots where enemies stay in range longest.
In co-op matches, split responsibilities across route sections with your team instead of stacking every defense in the same location. Distributed upgraded cores cover far more threats.
Weapons, Progression, and Unlocking Better Options
Beyond placed units, Untitled Defense documents several melee weapons — the Wooden Club, Metal Rod, Mace, and Basic Hammer — for close-range combat when enemies get too close. Weapon balance changes through updates, so compare them using current values.
Progression resources also shape which units you can field. Gold, Basic Crates, and Complex Crates feed the unlock loop that expands your available options.
| Resource / Weapon | Type | Role |
|---|---|---|
| Gold | Resource | Core progression currency for unlocks and flexibility |
| Basic Crate | Crate | Entry-level reward source for early collection building |
| Complex Crate | Crate | Higher-value rewards for long-term goals |
| Wooden Club | Melee | Basic close-range backup option |
| Metal Rod | Melee | Close-range option, compare current damage values |
| Mace | Melee | Direct melee damage for nearby enemies |
| Basic Hammer | Melee | Alternate melee choice, affected by balance patches |
Best Units Checklist:
- Secure early coverage without overspending
- Establish overlapping attack zones
- Fully upgrade at least two core units
- Keep a resource reserve for tough waves
- Reinforce before each boss wave
- Re-evaluate picks after every balance update
Consistent completed runs build your account faster than repeatedly failing hard waves. Stable defenses first, ambitious pushes second.
FAQ
Q: What are the best units in Untitled Defense for bosses?
The best units for bosses are fully upgraded core defense units with long range placed where enemies stay in range longest. Bosses like Chained Boss and Confinement require sustained damage, so max out your strongest positions and keep reserve resources before the boss wave begins.
Q: Should I add more units or upgrade existing ones?
Once basic route coverage is secure, upgrading your best existing units is generally more efficient than filling every position with low-level units. Upgraded cores deliver more sustained damage per resource spent, which matters against Tank Zombies and bosses.
Q: How do balance updates affect the best unit picks?
Official update logs regularly adjust towers, weapons, and enemies. A buff or nerf can shift tier rankings, so re-check your upgrade priorities and placement plans after each patch before committing resources to a long match.
Q: Which units handle Fast Zombies and Turbots best?
Speed-based enemies punish gaps in coverage. Use units with overlapping attack zones so fast threats cannot slip past a single defensive position, and make sure multiple towers can target the same route section.
