Heroes Assemble is a strategy RPG with rogue-like dungeon elements, developed by GZ Wegame. Released in February 2025 and built with HTML5 technology, the game has earned an 8.8/10 rating from over 6,400 votes on CrazyGames.

Set in a world torn apart by an interdimensional time shift, you assemble a squad of heroes to rescue people from an otherworldly siege. The game blends squad-building strategy, semi-idle progression, and hack-and-slash combat with anime-inspired 2D visuals and crisp animations.

With 28 collectible heroes, a companion pet system, and diverse modes including boss battles, arenas, alliances, leagues, and ruins, this browser game delivers deep strategic RPG gameplay.

It runs on desktop, mobile, and tablet browsers, and is also available as an app on iOS and Android. Every decision — which heroes to deploy, when to cast abilities, which boosts to pick — determines whether you conquer the dungeon or fall to its bosses.

Heroes Assemble uses simple mouse and touch controls: No keyboard controls are needed. The game was designed for mobile-first interaction, so all gameplay is handled through click or tap. You have access to 28 heroes in total, but only 4 can be deployed per squad.

Choosing the right combination is critical. Each hero fills a role: A balanced squad with at least one front-liner, a mix of ranged attackers, and a support character gives you the versatility to handle different enemy types across dungeon waves.

Heroes are acquired and upgraded through card fragments. Collect enough fragments of a specific hero to unlock them, then continue collecting to increase their star level and stats.

Focus your fragment resources on your core squad of four rather than spreading them across many heroes — a concentrated, upgraded team outperforms a diluted one. Every hero can be paired with a companion pet that provides combat bonuses and assists during battles.

Pets are collectible, upgradeable, and have unique abilities. Pairing the right pet with the right hero unlocks synergies — for example, matching a damage-boosting pet with your primary attacker amplifies their output significantly.

Battles play out in a semi-idle format: your heroes auto-attack during combat, but you manually control their ultimate abilities. When a hero's energy bar fills up, click their portrait to unleash a powerful skill.
