All Star Tower Defense X Summer Update 2 New NPC Missions

The Summer Update 2 has fundamentally changed the NPC quest landscape in ASTD X, introducing multiple layers of hidden content that even veteran players are discovering. Based on my extensive testing and exploration, here’s every single new NPC mission you need to know about.

Eren & Asta Evolution NPCs: The Edge Explorers

The first major addition comes in the form of evolution-focused NPCs located at the edge of the world map. These aren’t your typical lobby NPCs – you’ll need to venture to the outer boundaries of the game world to find them.

Exact Location Process:

Start from the main lobby spawn point
Head towards any edge of the map (north, south, east, or west boundaries work)
Look for the mission-giving versions of Eren and Asta near the world boundaries
Both NPCs will have visible question marks above their heads when missions are available

These NPCs offer Act 2 and Act 3 evolution missions, which are essential for players looking to upgrade their Eren and Asta units to their maximum potential. The missions themselves are relatively straightforward if you’ve got a solid team composition, but they’re crucial for unit progression.

Mission Details:

Eren NPC Mission: Focuses on Act 2 evolution materials
Asta NPC Mission: Provides Act 3 evolution components
Difficulty Level: Moderate (requires decent unit setup)
Time Investment: 15-20 minutes per mission
Rewards: Exclusive evolution materials not available elsewhere

Asta Evolution NPC: The Outfits Area Secret

For players specifically wanting to evolve their 3-star Asta into the much more powerful 4-star version, there’s a dedicated NPC near the Outfits area that many players walk right past without noticing.

Finding the Asta Evolution NPC:

Navigate to the Outfits area (where you purchase cosmetic skins)
Look around the perimeter of the Money Corp Shop building
The Asta NPC will be positioned near but not directly in front of the shop
This NPC specifically handles 3-star to 4-star Asta evolution

This evolution is particularly valuable because the 4-star Asta remains viable even into mid-game content, making it an excellent investment for players who haven’t pulled higher-tier units yet. The quest itself is designed to be accessible, requiring only basic team composition skills.

For players new to All Star Tower Defense X codes, make sure to redeem active codes before attempting these missions, as the extra gems and trait burners can significantly improve your success rate.

The Developer Mission: Cloud Climbing Adventure

This is where things get interesting. The Developer Mission is arguably the most creative and challenging NPC quest in Summer Update 2, requiring both skill and persistence to complete.

Complete Developer Mission Walkthrough:

Step 1: Navigate to Trial Area

Go to the Trial area on your map
Head towards the back section where you’ll see tall buildings with bells
These buildings are key landmarks for navigation

Step 2: Cloud Jumping Sequence

Look for a yellow cloud positioned near the bell buildings
Use shift + double jump or equip a mount for better mobility
Jump onto the first yellow cloud

Step 3: The Ascension Process

Continue ascending from cloud to cloud in sequence
You’ll encounter a giant plant structure – this is your main climbing path
Keep climbing and jumping between platforms
The path requires precise timing and movement

Step 4: Final Platform

After extensive climbing, you’ll reach another cloud platform
Look for a ledge with an NPC positioned on it
This is the Developer NPC you’ve been searching for

Rewards from Developer Mission:

Free emote (exclusive to this quest)
Gems (amount varies but typically 100-300)
Bragging rights (seriously, most players never find this)

Pro Tips for Developer Mission:

Bring a mount if you have one – it makes jumping significantly easier
Don’t rush the climbing sequence – precision over speed
If you fall, you’ll need to restart the entire climbing sequence
The mission is permanent once unlocked, so take your time

Understanding the All Star Tower Defense X traits tier list can help you optimize your units before attempting these challenging missions.

Guru Secret Mission: The Ultimate Challenge

The Guru Secret Mission represents the pinnacle of hidden content in Summer Update 2. This quest requires significant preparation and grinding, but offers access to exclusive content that most players will never experience.

Locating the Grand Elder Guru: The Guru NPC is located in the Grand Elder building, the same area where you’ll find the Ramen Grill-Master for other ascension quests. However, accessing his secret mission requires a very specific dialogue sequence.

Critical Dialogue Sequence (Must Be Exact):

“Why can’t you stand up?”
“Why are you so big?”
“Can you unlock my potential instead of my units?”
“What if I bring you food?”

Important Notes About Dialogue:

The sequence must be followed exactly as written
Any deviation will prevent access to the secret mission
You can retry the dialogue if you make a mistake
The Guru will only respond positively to this specific sequence

The 200 Hearty Ramen Requirement:

After completing the dialogue sequence successfully, the Guru will request 200 Hearty Ramen to unlock the secret mission. This is where the real grind begins.

Hearty Ramen Farming Strategy:

Primary Source: Any Naruto story mode arc
Best Farming Location: Naruto Arc 1 (fastest completion time)
Drop Rate: Varies but typically 1-3 Hearty Ramen per completion
Time Investment: Expect 10-15 hours of grinding for 200 ramen
Efficiency Tips: Use auto mode when possible to reduce active play time

Advanced Farming Techniques:

Team Composition: Use units that can solo clear Naruto stages
Auto Mode Strategy: Set up units that can handle waves independently
Session Planning: Farm in 1-2 hour sessions to avoid burnout
Progress Tracking: Keep a count of your ramen collection

Frequently Asked Questions

What’s the easiest way to find all NPCs in Summer Update 2?

Start with the edge of the map for Eren and Asta NPCs, then check the Outfits area for the Asta evolution NPC. Save the Developer Mission and Guru quest for last, as they require the most preparation.

How long does it take to collect 200 Hearty Ramen for the Guru quest?

With efficient farming in Naruto story modes, expect 10-15 hours of gameplay. Using auto mode and focusing on the fastest-clearing arcs can reduce this time significantly.

Can I complete the Developer Mission without a mount?

Yes, but it’s much more challenging. The shift + double jump technique works, but requires precise timing. A mount makes the cloud jumping sequence significantly easier.

Do NPC missions reset daily?

No, most NPC missions are one-time completions that provide permanent rewards. However, some NPCs offer multiple missions that unlock sequentially after completing previous ones.

What happens if I fail an NPC mission?

You can retry most NPC missions immediately. There’s no penalty for failure except the time invested. Some missions may have cooldown periods before retry attempts.

Are Summer Update 2 NPCs limited time only?

No, all NPCs introduced in Summer Update 2 are permanent additions to the game. You can complete these missions at your own pace without worrying about expiration.

Which Summer Update 2 NPC mission should I prioritize first?

Start with the Asta evolution NPC near the Outfits area if you have a 3-star Asta, as it provides immediate unit improvement. Then work on Eren and Asta edge NPCs for evolution materials.

Can I complete NPC missions in any order?

Most NPC missions can be completed in any order, but some may have prerequisites. The Guru secret mission requires the specific dialogue sequence, and some ascension missions need you to own the corresponding unit.

What’s the best strategy for the cloud jumping Developer Mission?

Take your time and don’t rush. Use a mount if available, and practice the jump timing. If you fall, restart patiently – the mission is permanent, so there’s no time pressure.

Do I need specific units to complete Summer Update 2 NPC missions?

While having strong units helps, most missions are designed to be completable with various team compositions. Focus on your best-leveled units with good traits rather than specific characters.

The Summer Update 2 in All Star Tower Defense X has transformed the NPC quest landscape, offering both new and veteran players exciting content to explore. From the straightforward Asta evolution near the Outfits area to the epic challenge of collecting 200 Hearty Ramen for the Guru secret mission, there’s content for every skill level and commitment level.

Remember that these NPCs represent permanent additions to the game, so you can progress at your own pace without missing out. Whether you’re climbing clouds for the Developer Mission or grinding Naruto stages for ramen, each quest offers unique rewards and experiences that enhance your ASTD X journey.

The key to success lies in preparation, patience, and persistence. Start with the easier missions to build confidence and resources, then gradually work your way up to the more challenging content.
