Best Gundam Assemble Expansions to Buy First (Beginner Upgrade Guide)

Why Expansions Matter in Gundam Assemble

Starter sets teach you the game. Expansions are what make the game start feeling like it belongs to you.

That is especially true in a system like Gundam Assemble, where the smaller squad structure means every added unit has the potential to matter a lot. In a huge army-scale game, one extra box may barely change how your force plays. In a smaller tactical game, one expansion can reshape how you build, how you position, and what kind of battle plan feels natural to you.

That is why expansions matter so much here. They are not just “more product.” They are the first real step into customization. They are what take you from learning the rules to making choices. Once you start adding expansion packs, you stop just asking, “How do I play Gundam Assemble?” and start asking, “What kind of Gundam Assemble player do I want to be?”

Should You Buy an Expansion Before or After ST01?

For most beginners, the answer is simple: buy the starter set first, then buy your first expansion.

This is the cleanest path because the starter gives you the foundation you need to understand what an expansion is actually adding. Without that foundation, it is easy to buy based only on hype, packaging, or the assumption that “more must be better.” In practice, more only helps once you understand how the game flows and what roles you actually want to add to your squad options.

That is why the smartest beginner path is sequential. Learn the language of the game with ST01. Play a few battles. Notice what excites you most. Then upgrade. That order makes your expansion choice much more useful, because you are buying from a position of understanding rather than guesswork.

Best Gundam Assemble Expansions to Buy First

At the moment, the current beginner-relevant expansion conversation centers around three products: Expansion Pack 03 [EX03], Expansion Pack 04 [EX04], and Expansion Pack 05 [EX05]. The early product structure points to a very important takeaway: these are not random add-ons. They are built to let players assemble more custom squads and move beyond the starter experience.

Because the currently published product details for EX03, EX04, and EX05 follow a very similar structure, the “best” first expansion is less about one pack obviously dominating the others and more about which one fits your preferred next step best. That said, there is still a practical beginner order that makes sense.

How to Choose the Right First Expansion

Most beginners make expansion decisions the wrong way. They either buy too much too early, or they try to force a ranking that is more precise than the public information actually supports at launch. A better approach is to ask the right questions.

• Do you want the simplest possible first upgrade after ST01?
• Do you want more squad-building flexibility right away?
• Are you buying primarily for gameplay, collecting, or painting?
• Do you want one expansion first, or are you planning a small upgrade bundle?

If you want the simplest answer, choose EX03 first. It is the cleanest “starter-plus-one” path. If you already know you want to build a broader early collection, then EX04 and EX05 both make excellent next purchases because they keep that momentum going. The goal is not to own everything immediately. The goal is to add enough variety that your next few games feel fresh and your collection starts feeling customizable.

Why EX03 Is a Great First Upgrade

Expansion Pack 03 [EX03] is the easiest overall recommendation for one reason above all others: it is the cleanest first step beyond the starter. When a beginner asks, “What should I buy next?” the smartest answer is usually the product that adds meaningful variety without making the upgrade path feel messy. EX03 fits that role very well.

The reason this works is psychological as much as practical. Beginners often do best when they move from a stable foundation into one controlled expansion step. EX03 feels like that kind of purchase. It is not the “buy everything” answer. It is the “make your next games more interesting” answer.

It also works well because the published expansion structure is consistent: miniatures, unit cards, tactical cards, and a token. That means EX03 is not just decorative. It is a true add-on built to support custom squad development rather than a side accessory product.

Why EX04 Is a Strong Next Pick

Expansion Pack 04 [EX04] makes a lot of sense once you know you are not stopping at a single add-on. If EX03 is the best one-expansion recommendation, EX04 is the natural “I want more variety now” follow-up.

That matters because Gundam Assemble is not the kind of game where extra pieces sit quietly in the background. In a smaller squad-based game, new units can change how your decisions feel very quickly. More options means more ways to test different battle rhythms, more ways to build around preferences, and more ways to make the game feel less like a fixed starter experience and more like an evolving system.

EX04 is therefore a strong choice for players who already know the starter clicked for them and want their next purchase to expand the sense of possibility. It is not about replacing EX03. It is about building outward from it.

Why EX05 Belongs on Your Upgrade List

Expansion Pack 05 [EX05] belongs in the same conversation because early Gundam Assemble collecting is not just about buying a first pack. It is about deciding whether you are building a one-step upgrade or a real early collection path.

EX05 is attractive for players who already know they like the direction of the game and want to keep building momentum. Once you stop thinking of expansions as isolated purchases and start thinking of them as collection layers, EX05 becomes very easy to justify. It helps round out the early expansion lineup and supports the idea that Gundam Assemble is a game you grow into rather than a single-box curiosity.

For hobby-minded buyers, it also strengthens the appeal of the line as a whole. More miniatures means more painting opportunities, more display options, and more personal connection to your force on the tabletop. That side of the value is easy to underestimate until you actually start building a collection.

Best Beginner Buying Path After the Starter

If you want the simplest buying path, use this:

Common Expansion Buying Mistakes to Avoid

Beginners usually go wrong in one of three ways.

• Buying expansions before understanding the starter. This often makes the game feel more complicated than it really is.
• Trying to solve the whole collection path immediately. You do not need a perfect end-state plan to make a smart first purchase.
• Ignoring your actual enjoyment style. Some players care most about gameplay flexibility. Others care most about painting and collecting. Your best expansion path should reflect that.

The smartest path is staged, not frantic. Build a foundation. Add one meaningful expansion. Then decide whether you want broader tactical variety, more collection depth, or more hobby value. That is the best way to make your early Gundam Assemble purchases feel good instead of rushed.
