All Star Tower Defense Beginner Guide (2026) — Start Here

All Star Tower Defense (ASTD) is one of the most popular tower defense games on Roblox, with over 7.6 billion visits as of July 2026. The concept is straightforward — summon anime-inspired units, place them on a map, and defend against waves of enemies. But underneath that simple premise sits a gacha summoning system, multiple currencies, evolution mechanics, and a surprisingly deep team-building layer that can overwhelm new players fast.

This guide covers everything you need to go from your first login to confidently clearing World 1 content. We'll break down every mechanic that matters, the mistakes that waste your Gems, and the exact strategy to build a strong roster early. If you're also hunting for free rewards, check our active ASTD codes list — we update it daily.

Your First 30 Minutes

When you first load into ASTD, the game drops you into a lobby with a tutorial prompt. Don't skip it. The tutorial walks you through placing a unit, upgrading it mid-wave, and surviving a basic map. It takes about three minutes and gives you 100 Gems as a reward.

After the tutorial, head straight into the Beginner Saga. This is a short set of story missions designed for fresh accounts. Each mission rewards between 50 and 150 Gems on first clear, and the enemies are weak enough that even your starting units can handle them. Clear all of these before doing anything else — you'll walk away with roughly 500 Gems.

Now it's time for your first summon. Head to the Gate (the summoning banner area) and spend your Gems. A single summon costs 50 Gems, and a multi-pull (10 summons) costs 500. Do the multi — you're guaranteed at least one 4-star or higher unit, and the odds are better per Gem spent.

With your new units, jump into World 1 maps. Start with Hidden Village and Leopard Base. These are the easiest maps in the game and perfect for learning enemy pathing, placement spots, and upgrade timing. Play at 1x speed for your first few runs. Yes, it's slower. But you'll actually see how enemies move, which lanes matter, and when you need to upgrade instead of place new units.

Core Mechanics Explained

ASTD has several systems running at once. Here's what each one does and why it matters for new players.

Gems — Your Primary Currency

Gems are what you spend to summon units at the Gate. They're the most important currency in the game, and you'll never feel like you have enough. Here's where they come from:

• Story missions: 50–200 Gems per first clear
• Daily tasks: Up to 300 Gems per day if you complete all of them
• Extreme difficulty clears: 500+ Gems for first-time completion
• Codes: Anywhere from 50 to 500 Gems each (see our codes page)
• Login rewards: Scaling rewards, roughly 1,500–2,000 Gems per month

If you do your dailies consistently, you'll earn around 9,000 Gems per month. That's 18 multi-summons — not bad for free.

Stardust — Your Upgrade Currency

Stardust is what you use to level up and evolve units. You earn it by clearing maps, completing raids, and selling duplicate units. Don't underestimate how much you'll need — evolving a single 6-star unit can cost 5,000–15,000 Stardust depending on the character.

Unit Rarity

Units in ASTD range from 3-star to 7-star rarity. Here's the quick rundown:

Rarity	Pull Rate	Notes
3-Star	~40%	Fodder. Sell for Stardust.
4-Star	~30%	Usable early game. Check if they're evo material before selling.
5-Star	~20%	Solid units. Some are meta even at 5-star.
6-Star	~9%	Strong out of the box. Can evolve for massive power spikes.
7-Star	~1%	The best units in the game. Usually limited banner exclusives.

Evolution

This is where ASTD gets interesting. Once a 6-star unit hits max level, you can evolve it using Stardust and sometimes duplicate units as material. Evolution typically boosts a unit's DPS by 3–5x and unlocks a new ability. The power difference between an unevolved and evolved 6-star is enormous — it's essentially a different unit.

Not every 6-star can evolve, though. Check the unit's info page to see if an evolution path exists. Prioritize evolving your main DPS units first, since they'll carry you through harder content.

The Leader Slot

The first unit in your loadout becomes your leader. This isn't just cosmetic — your leader provides a passive buff to your entire team during the match. The most useful leader buff for beginners is money boost, which increases the in-game cash you earn per wave. More cash means placing and upgrading units faster, which means surviving harder waves.

Always use a money-boost leader until you're experienced enough to know when a different buff is better. It's that important.

Farm Units

Farm units don't attack enemies. Instead, they generate in-game money each wave, letting you afford more units and upgrades. The key farm units are Pizza Girl, Jeff (CEO), and Idol. You want at least one farm unit in every team. Without farm, you'll run out of money by wave 10 and watch enemies walk past your under-leveled defense.

Game Modes

ASTD has three main modes:

• Story mode: Clear maps across multiple worlds for Gems, Stardust, and unit rewards.
• Raids: Co-op boss fights with unique rewards. Great for Stardust farming.
• Infinite mode: Survive as many waves as possible. Used for testing teams and earning leaderboard bragging rights.

For beginners, story mode is your bread and butter. Raids become important once you need specific evolution materials. Infinite mode is mostly endgame content. For a breakdown of which units perform best across all modes, check our ASTD tier list for 2026.

10 Beginner Mistakes to Avoid

We see new ASTD players fall into the same traps over and over. Here are the ten biggest ones and how to dodge them.

1. Spending all your Gems on the standard banner. Standard banner units are available permanently. Limited banners rotate every few weeks and contain some of the strongest units in the game. A limited banner pity is 50 summons (2,500 Gems), so save your Gems for when a good limited unit drops. You'll thank yourself later.
2. Ignoring the leader slot buff. Plenty of beginners just throw their strongest unit in the first slot without checking the leader ability. A money-boost leader gives your entire team more income per wave. That snowballs into placing units earlier, upgrading faster, and surviving waves you shouldn't. Always check what buff your leader provides.
3. Not using farm units. Farm units like Pizza Girl or Jeff (CEO) seem useless because they don't attack. But they generate the in-game cash you need to place and upgrade DPS units. Without farm, you'll consistently run out of money around wave 8–12 and lose maps you should be winning. One farm unit per team is the minimum.
4. Playing on fast-forward before learning maps. ASTD lets you speed up waves to 2x and 3x. That's great once you know the enemy patterns. But on your first run of a map, play at 1x speed. Watch where enemies spawn, which path they take, and where bottlenecks form. Losing because you couldn't react fast enough on 3x is avoidable.
5. Neglecting to evolve key DPS units. An unevolved 6-star unit deals maybe 8,000–12,000 DPS. That same unit evolved often hits 35,000–50,000 DPS. The power gap is massive. Once you have a 6-star DPS at max level, prioritize their evolution above almost everything else. It's the single biggest power jump in the game.
6. Missing daily tasks. Daily tasks reward around 300 Gems per day — that's 9,000 Gems per month. Missing even a few days adds up fast. It takes roughly 10 minutes to complete all dailies. Make it a habit every time you log in.
7. Forgetting to redeem codes. The developers release codes regularly that give free Gems, Stardust, and sometimes exclusive units. We track every active code on our ASTD codes page. Check it weekly and never leave free rewards on the table.
8. Over-leveling weak units instead of saving resources. It's tempting to level every unit you pull. Don't. Stardust is limited, especially early on. Focus your Stardust on your best 4–5 units. Leveling a 3-star unit to max is a waste of resources that could've gone toward evolving a 6-star.
9. Ignoring Raids entirely. Some beginners stick to story mode and never touch Raids. That's a mistake. Raids give excellent Stardust, unique materials, and sometimes exclusive unit drops. You can queue into Raids with random players, so you don't need a premade team. Start running them as soon as they unlock.
10. Selling 4-star+ units without checking evolution requirements. Some 4-star and 5-star units are required as evolution material for 6-star units. If you sell them for Stardust, you'll have to re-pull them later — which could take hundreds of Gems. Always check if a unit is needed for an evolution before you sell it.

Best Starter Strategy

Here's the game plan for your first week in ASTD. Follow this and you'll have a functional team and a steady Gem income faster than 90% of new players.

Ideal Beginner Team Composition

Your team should have five roles covered:

Slot	Role	Recommended Unit
Leader	Money-boost leader	Any unit with a cash-per-wave leader buff
Slot 2	Farm unit	Pizza Girl or Jeff (CEO)
Slot 3	Main DPS	Killer (Serious) — excellent early game
Slot 4	Secondary DPS	Any 5-star or 6-star damage dealer
Slot 5	Support / Slow	Any unit with slow or debuff abilities

Killer (Serious) deserves a special mention. He's a relatively common pull, easy to level, and his DPS output rivals some 6-star units until mid-game. If you pull him early, invest in him without hesitation.

Week 1 Progression Path

1. Complete the tutorial and all Beginner Saga missions for ~500 starting Gems.
2. Do your first multi-summon (500 Gems) at the Gate. Build your team around whatever you pull.
3. Farm Hidden Village and Leopard Base on Normal difficulty. Clear each 3–5 times to learn the maps.
4. Complete daily tasks every single day. This is your primary Gem income.
5. Once your team can handle Normal comfortably, push Extreme difficulty on the maps you've cleared. First-time Extreme clears give 500+ Gems each.
6. Redeem all active ASTD codes for bonus Gems and Stardust.
7. Save Gems for the next limited banner instead of dumping them into the standard banner.

By the end of week one, you should have cleared most of World 1 on Normal, a few Extreme clears under your belt, and 2,000–3,000 Gems saved toward a limited banner. That's a strong position.

When to Spend Robux (and When Not To)

ASTD has several Robux purchases available. Some are genuinely good deals. Others are traps that drain your wallet without meaningfully improving your account.

Worth Buying

VIP Gamepass (varies, typically 799–999 Robux) — This is the single best Robux purchase in ASTD. It doubles your Gem rewards from story missions, dailies, and other sources. Over a month of active play, VIP easily pays for itself in extra Gems. If you're going to spend any Robux at all, this is where it goes.

Extra team slots — Having more team presets lets you save different loadouts for different map types. Not essential, but a nice quality-of-life upgrade once you have enough units to justify multiple team builds.

Not Worth Buying

Individual Gem packs — Buying Gems directly with Robux gives you terrible value compared to VIP. A Gem pack might give you 1,000 Gems for 400 Robux. VIP gives you thousands of bonus Gems over time for the same Robux. The math is not close.

Standard banner summons with Robux — Never do this. Standard banner units are available forever. You'll pull them naturally over time. Spending Robux on standard summons is like paying premium price for something that's regularly on sale for free.

Limited banners rotate regularly — save your Gems (and Robux) for meta units. Not every limited unit is worth chasing. Check our tier list to see which ones are actually strong before you commit.

If you don't want to spend real money at all, our ASTD free Robux guide walks you through earning Robux through Earnaldo and putting it toward game passes without opening your wallet.
