All 25+ Units in Cube Kingdoms: The Complete List & Unlock Guide

This is the complete, definitive list of all 28 unlockable units in Cube Kingdoms. Forget scattered forum posts and incomplete wikis; this guide provides the full roster, breaking down every unit's faction, role, core ability, and—most importantly—exactly how to unlock them. The units are divided into four distinct factions: the defensive Stoneborne Legion, the high-damage Sunstone Archers, the controlling Voidforged Mages, and the cunning Gilded Syndicate. Understanding how to acquire and combine these units is the single most important factor in conquering the game's toughest challenges, from the Sunken City to the final boss in the Crimson Spire.

For players who just need the quick facts, this table summarizes every unit in the game. More detailed breakdowns of each faction, including strategic advice for each unit, can be found in the sections below.

02

The Stoneborne Legion: Your Frontline Foundationtag

The Stoneborne Legion is the backbone of any durable army. These units excel at absorbing damage, controlling enemy positions, and protecting your more fragile backline. Their abilities often involve stunning enemies, increasing their own armor, or reflecting damage. A strong Stoneborne frontline is the easiest way for new players to progress through the early campaigns.

If you believe the best defense is an overwhelming offense, the Sunstone Archers are your faction. These units specialize in dealing massive damage from a safe distance.

05

The Gilded Syndicate: Cunning, Greed, and Trickerytag

06

Key Unit Synergies and Team Buildingtag

Simply unlocking units isn't enough; combining their abilities is where true power lies. Here are a few classic army compositions to get you started:

• The Unbreakable Wall: This build focuses on pure survivability. Use a frontline of Granite Guards and a Mountainheart Titan, backed by one or two Runic Healers. Your damage will be slow, but you'll be able to outlast almost any enemy wave.
• Glass Cannon Barrage: The goal here is to eliminate enemies before they can act. Use a single Boulder Brawler to stall, and fill the rest of your backline with Sunbeam Arbalists, Twinshot Renegades, and a Skyfire Bombardier. Protect them at all costs.
• The Gold Rush: An economy-focused build for farming resources. Start with multiple Gold Goblins and an Alleyway Cutpurse. Use the extra income to quickly upgrade and deploy a powerful late-game unit like The Collector or Aetherfiend far earlier than you normally could.
• Control Freak: This composition denies the enemy any agency. Combine the Chrono-Warden's freeze, the Master Trapper's root, and the Stonefist Champion's stun to keep the enemy army permanently locked down while your DPS units pick them apart.

07

Frequently Asked Questions (FAQ)tag

What's the hardest unit to unlock in Cube Kingdoms?tag

The Aetherfiend is widely considered the most difficult unit to acquire. It requires not only completing the entire main campaign but also defeating the notoriously challenging secret boss in the Void Vortex, which has unique mechanics not seen anywhere else in the game.

What's the best starting unit to focus on?tag

For new players, the Boulder Brawler is the most reliable starting unit. It's tanky, has decent damage, and its evolution, the Stonefist Champion, provides valuable crowd control. Investing in your frontline early is never a bad strategy.

Can you permanently miss unlocking a unit?tag

No. The developers have confirmed that no unit is permanently missable. The "Crimson Comet" world event for the Comet Caller will eventually cycle back, and all other achievement- and progression-based unlocks can be attempted at any time.

Which faction is the strongest overall?tag

There's no single "strongest" faction, as they are designed to be balanced and situational. However, the Stoneborne Legion provides the most consistent value across all stages of the game due to the universal importance of a strong frontline.

How do you get Titan Fragments for the Mountainheart Titan?tag

Titan Fragments are rare drops exclusively from the final boss chest of each level within the Crystal Caves campaign. You have a higher chance of receiving one on higher difficulty settings. You need to collect all three unique fragments—the Head, the Core, and the Chassis—to unlock the unit.

Closing Taketag

While it's tempting to find a favorite unit and use it exclusively, the true depth of Cube Kingdoms comes from its roster's breadth. Each of the 28 units has a specific niche, a counter, and a synergy. Experimenting with different combinations for different challenges is the core of the game's strategy. This list is your toolbox; now go build the perfect army.
