Squad Busters

Review by eFreeware

The most distinctive thing about Squad Busters is its cast. Supercell has pulled characters from Clash of Clans, Brawl Stars, Hay Day, Clash Royale and Boom Beach and put them into one roster of more than 25 fighters. Rather than building a game around a single universe, the studio treats its own back catalog as a shared toy box, and everything here flows from that decision.

That makes it a game for people who already know these characters, but also for anyone who likes the idea of a multiplayer action game where the lineup you bring matters as much as how you play it. Matches are built around picking a Hero and a squad, then using their combined abilities to outlast everyone else in the lobby.

It is free to download, carries no ads, and offers in-app purchases. It has been installed over 50 million times and holds a 4.2 average from more than 728,000 ratings, which is a healthy sign for a game that arrived in May 2024 and is still being updated, most recently in December 2025.

Below I go through what the game asks of you, how its main systems fit together, and what kind of player is likely to get the most out of it.

A mashup roster that does the heavy lifting

Collecting and evolving characters is the spine of the whole experience. Each fighter comes with their own skills, and the developer frames the roster as a set of building blocks rather than a simple power ladder: you are meant to assemble combinations that suit a particular battle instead of settling on one favorite and grinding it upward.

That is a more interesting pitch than a straightforward collection game. If the characters genuinely play differently, the appeal is in working out which mix covers your weaknesses and which one lets you press an advantage. The evolution side gives that experimentation a longer arc, since a character you invest in presumably changes as it grows.

The cross-game casting does more than provide familiar faces. Characters from a farming game and characters from a competitive shooter are unlikely to fill the same role, so the roster naturally pushes toward the kind of team-building decisions the game is built around. For players who have spent time in any of those five games, there is an immediate shorthand; for everyone else, it is simply a large cast with distinct jobs to learn.

Hero, squad and the tactics of a single match

A match starts with a choice: pick your Hero and the squad that supports them. From there, the developer says tactics and skill decide the outcome, which tells you this is not a game where the better collection wins automatically. You are setting up attacks and defending your Hero at the same time, so the decision-making runs in two directions at once.

The pace is part of the pitch: running, fighting, throwing a large bomb, thinking fast about the right mix of tactics. There are also fusion troops to spark, which suggests moments where several units combine into something bigger and the match tilts. The developer notes there is more than one route to victory, which is the kind of claim that matters in a competitive game, since it implies you can play cautiously or gamble on a knockout rather than following a single script.

What I like about this framing is that it puts the interesting decisions before the fighting rather than during it. Choosing a Hero and a squad is a commitment, and living with that commitment for the length of a match is where the strategy sits. Players who enjoy drafting a plan and then executing it under pressure will find more here than those who want pure reflex-driven action.

Modes and modifiers keep matches from repeating

The game spreads its action across several modes, including Mayhem, Squad League, Gem hunt and Duos. Each one changes what you are trying to do in a match, and Duos in particular pairs you with someone else rather than leaving you to fend for yourself. Switching between them is the main way the game avoids feeling like the same fight on a loop.

On top of the modes sit modifiers, which are the source of surprises from game to game. Loot Goblins can be chased down, Piñatas smashed, and Royal Ghosts recruited to haunt other players. These are the sort of additions that change the rhythm of a match without demanding a new set of rules, and they give an experienced player something to react to rather than simply repeat.

The combination is the point. A mode sets the objective and a modifier scrambles the middle of the match, so the same squad can play very differently depending on what shows up. For a game built on collecting and combining characters, that variety is what keeps the roster worth expanding.

Worlds, maps and the road through them

Progress runs through themed Worlds and maps, with unique environments, bosses and traps along the way. This gives the game a structure beyond individual matches: there is a journey to move along, and the scenery changes as you go rather than staying fixed.

Bosses and traps are the parts I find most promising. They suggest that not every threat comes from another player, and that map knowledge has value. Unlocking heroes and villains as you progress also ties the single-player-facing side of the game back to the roster, so time spent advancing feeds directly into the squads you can build.

Anyone who needs a sense of forward motion to stay interested will likely appreciate this layer. It sits alongside the competitive modes rather than replacing them, which means the game can be approached either as a series of matches or as a longer climb through its worlds.

Playing with people you actually know

Squad Busters lets you set up your own multiplayer Party room, which is the feature that changes the game most for me. Instead of dropping into a lobby of strangers, you can gather friends and family and settle who has put together the better squad setup, with survival in the battle deciding the argument.

The developer's phrasing about friends, family and frenemies captures why this matters. A private room turns the game into something you can organize an evening around, and it gives the squad-building system a social payoff: you are not just optimizing for yourself, you are trying to outthink people who know how you play.

The game may ask for camera access to scan QR codes and for permission to send notifications. Both are optional, and the game can be played whether or not you agree to them, though some features may not work as intended if you decline. That is a reasonable arrangement, and it means a parent setting the game up for a child can leave the optional permissions off and still expect the core experience to work.

What kind of player this fits

This is a game for people who enjoy assembling a team more than mastering a single character. If your idea of a good time is weighing which combination of abilities handles the lobby in front of you, the roster of more than 25 fighters and the evolution system give you plenty to work with. The rotating modes and modifiers reinforce that, because they keep changing the problem you are solving.

It also suits players who want competition with a social edge. The Party room makes it easy to play against people you know, and Duos gives you a partner when you would rather not go alone. The 4.2 average across a very large number of ratings suggests the formula lands with a broad audience, and the Everyone 10+ rating means it is pitched at a wide age range.

The free download with no ads keeps the barrier low, though in-app purchases are part of the package, so anyone sensitive to spending inside a competitive game should go in aware of that. It is also a game that rewards familiarity with its cast, so the first stretch is partly about learning what each character actually does.

Players who want a long solo campaign with a fixed ending, or who dislike the idea of competing against other people at all, will find the emphasis here sits elsewhere. The game is built around matches, squads and other players, and that is where its attention goes.

A squad builder worth your time

Squad Busters is a confident, well-supported multiplayer game with a genuinely unusual hook: a roster drawn from five different Supercell worlds and a system that asks you to combine them rather than collect them for their own sake.

I would point it toward players who like drafting, experimenting with team compositions and competing in short matches, particularly those who already have affection for any of the characters on offer. It is free, ad-free and broad enough in rating to suggest it works for a wide range of ages.

The caveats are straightforward rather than hidden. In-app purchases exist, the game is built around playing with and against other people, and getting the most from the roster takes time spent learning it. If those fit how you like to play, this is an easy one to try.
