🔥 What Makes a Unit “Best” in ASTD?
Before choosing units, you need to understand what makes them powerful.
Key Factors:
1. Damage (DPS)
High damage units are essential for defeating enemies quickly.
2. Range
Units with a longer range can attack enemies for a longer time.
3. Attack Speed
Faster attacks mean more damage over time.
4. Scaling
Some units become stronger as the game progresses.
5. Special Abilities
Abilities like AOE damage or buffs can change the game.
👉 The best units combine multiple strengths.
⚔️ Types of Best Units You Must Have
💥 1. AOE Units (Area Damage)
These units attack multiple enemies at once.
Why They Are Important:
- Handle large waves
- Prevent enemy overflow
- Essential for early and mid-game
Strategy:
Place them in areas where enemy groups gather.
🎯 2. Single Target DPS Units
These units focus on one enemy at a time but deal massive damage.
Why They Matter:
- Best for bosses
- Critical in the late game
- High damage output
Strategy:
Use them alongside AOE units for balance.
⚡ 3. Hybrid Units (Best Overall)
Hybrid units combine AOE and DPS abilities.
Advantages:
- Flexible gameplay
- Useful in all modes
- Great long-term investment
👉 These are often considered the best units overall.
🧠 How to Choose the Best Units (Step-by-Step)
Step 1: Check Damage Stats
Always compare base damage and upgrade potential.
Step 2: Analyze Upgrades
Some units become powerful only after upgrades.
Step 3: Look at Range
More range = more damage time.
Step 4: Evaluate Cost Efficiency
Avoid units that are too expensive for their value.
Step 5: Follow the Meta
Stay up to date on the current best-performing units.
🏗️ Best Team Composition Strategy
A strong team is more important than individual units.
Ideal Team Setup:
- 1–2 AOE Units → Crowd control
- 1–2 DPS Units → Boss damage
- 1 Hybrid Unit → Balance
- Optional Support Unit → Buffs
Why This Works:
- Covers all situations
- Ensures survival in all modes
- Maximizes damage output
💡 Pro Tips For Using Best Units

Save for better units.
