TSUM: Co-op Play Guide for Alien Boss Raid (August 2026)

Introduction

TSUM is a Roblox adventure role-playing game where you collect adorable Tsum companions that provide stat boosts, special abilities, and extra loot during missions. As of August 2026, the game has refreshed content with the Alien Boss raid, a rerun of the Stardust Banner event, and a newly capped Taboo Summon at 100 trillion HP. While there are currently no codes to redeem, this page is monitored and updates the moment codes drop, so you can redeem them for rewards when available. This guide focuses on the co-op side of TSUM, breaking down how to find teammates, divide roles, and make the most of group play, especially for the challenging Alien Boss raid.

The code system in TSUM works through promotional releases by the developers, often during events or updates. Once codes are issued, you can typically redeem them in the game's settings menu or a dedicated codes section. Codes expire after a limited time, so it's crucial to use them promptly. Since no codes are active right now, we'll concentrate on mastering co-op gameplay to progress without them.

Overview of Multiplayer and Social Systems

TSUM integrates several multiplayer and social systems designed for cooperative play. The primary feature is the Alien Boss raid, a limited-time co-op mode where players team up to defeat a massive alien boss. The July 2026 update nerfed the raid's damage, making it more accessible for new and mid-level players. In this mode, up to four players can join forces, each contributing Tsum companions to a combined effort.

Another key social aspect is the Stardust Banner event, which reruns periodically and allows players to pull rare Tsums using Stardust currency. While not directly co-op, this event fosters community discussion and resource-sharing, as players strategize on saving Stardust for optimal pulls. Additionally, the game encourages social interaction through the official Discord server, where players exchange tips, form groups, and coordinate raid attempts. There is no player-versus-player combat, so all multiplayer interactions are cooperative, emphasizing teamwork over competition.

How to Find or Form a Group

Finding or forming a group in TSUM is straightforward, with several avenues available. The most effective method is using the official Discord server, which has dedicated channels for raid matchmaking. In these channels, players post their team composition, such as available Tsum roles and levels, and invite others to join. This allows you to assess compatibility before starting a raid.

In-game chat is another option; you can type messages to ask if anyone wants to run the Alien Boss raid or participate in other activities. If you have friends who play TSUM, simply invite them via the Roblox friend list to form a party. For beginners, look for groups that specify "carry" or "beginners welcome," as veteran players often assist newcomers in getting their first raid clear. Starting with a familiar group can reduce frustration and improve learning.

Role Division and Team Composition Tips

Successful co-op play in TSUM hinges on balanced team composition. You can equip up to four Tsums at a time, and each Tsum fulfills specific roles that are critical during raids like the Alien Boss. Before starting, communicate with your group to assign roles and ensure coverage of essential functions.

• Damage amplifiers: These Tsums boost the entire team's damage output when their abilities trigger. They are vital for quickly depleting the boss's health during phases, especially when coordinating Summon attacks.
• Shield generators: Tsums that create shields mitigate incoming damage, protecting squishier teammates from heavy attacks. In the Alien Boss raid, this role is crucial for survival during area-of-effect strikes.
• Support and healers: Tsums with healing or instant revive abilities provide a safety net. In co-op, they can turn a potential wipe into a narrow victory by keeping the team alive through prolonged fights.

For optimal play, aim to have at least one Tsum in each role within your group. If you're playing with randoms, try to cover these roles yourself by equipping a diverse set of Tsums. Planning ahead, even in casual groups, makes raids smoother and more enjoyable.

Cooperative Mechanics Explained

TSUM's cooperative mechanics center on the Summon button, a temporary power-up that scales with the team's overall strength. In the Alien Boss raid, the Taboo Summon caps at 100 trillion HP, meaning that on higher difficulties, multiple players must coordinate their Summons to stack effects effectively. Timing is key; avoid using Summons simultaneously unless the boss is about to enrage. Staggering them provides a longer window of boosted damage, maximizing efficiency.

The raid also rewards players based on contribution, which includes damage dealt, survival time, and support provided to allies. While the exact formula isn't public, this system encourages active participation and discourages leeching. By contributing meaningfully, you can earn better loot, such as rare Tsums or Stardust for upgrades.

Solo Alternatives for Group Content

Not everyone prefers group play, and TSUM accommodates solo alternatives. You can queue into the Alien Boss raid solo if you seek a challenge. With the 2026 nerf, a well-leveled team of four Tsums can handle it alone, but strategy is essential. Bring a self-sufficient team: one damage dealer, one shield generator, and one healer. Use your Summon at optimal moments and save Stardust for Tsum Lab upgrades that boost survivability, such as health or defense increases.

The Stardust Banner rerun is fully accessible solo, as it involves summoning Tsums individually. You never need a group to pull, but joining a raid group can increase your daily Stardust intake through co-op-related quests. This makes solo play viable, though you might miss out on some social benefits.

Frequently Asked Questions

Q: How do I unlock new Tsum companions in TSUM?

A: New Tsum companions are primarily unlocked through the Stardust Banner event, where you spend Stardust to pull from a randomized pool. Stardust is earned by completing missions, daily quests, and participating in raids like the Alien Boss. Some Tsums may also drop as rewards from specific activities, so engaging in co-op can accelerate your collection.

Q: What is the best strategy for the Alien Boss raid in August 2026?

A: The Alien Boss raid requires coordinated teamwork. Focus on staggering Summon attacks to maximize damage phases, and ensure your team has a mix of damage, shield, and healer Tsums. Communicate via in-game chat or Discord to plan role assignments, and aim to contribute consistently to earn better rewards. The recent nerf makes it more accessible, so don't hesitate to try it with a balanced group.

Q: Can I trade Tsum companions with other players in TSUM?

A: TSUM does not currently feature a direct trading system for Tsum companions. Instead, social interaction revolves around sharing tips on the Discord server, comparing collections, and collaborating in raids. You can discuss Tsum strategies and event approaches with others, but all Tsums are obtained individually through gameplay.
