Ye Olde CN Games - Ben 10 Ultimate Alien: Ultimatrix Unleashed

Verdict

5/10 — For die-hard Ben 10 fans only.

Ultimatrix Unleashed is a functional but forgettable licensed game. Young fans who love Ultimate Alien will enjoy smashing things as Ultimate Humungousaur for a few hours. Anyone else will find shallow combat, repetitive levels, and control frustrations. If you want a good Ben 10 game on DS, seek out Ben 10: Protector of Earth instead — it’s far superior. This one is strictly for completionists or kids who don’t mind repetition as long as the hero says “It’s hero time!”

Best for: Ages 6–10, Ben 10 collectors, short bus rides.
Skip if: You’ve played any other beat ’em up from 2010.

6. Ultimate Aggregor (The Dark Mirror)

While not part of Ben’s playable arsenal in the game, Ultimate Aggregor is the physical manifestation of the Ultimatrix’s potential for evil. By using the Ultimatrix’s evolutionary function on himself (due to his Osmosian powers), Aggregor becomes a perfect, evolved predator. He represents the "unleashed" nightmare scenario: what happens when evolution has no moral guardian.

The Core Mechanic: How "Unleashed" Changes Everything

The keyword here is Unleashed, and the developers took that literally. In most Ben 10 games, you switch aliens to solve puzzles or bypass obstacles. In Ultimatrix Unleashed, you switch aliens to survive. The game utilizes a quick-switch radial menu on the DS touch screen, allowing you to cycle through four active aliens in real-time.

But the headline feature is the Ultimatrix Overload Bar. As you land combos and defeat enemies, a meter fills up. Once full, you don’t just change forms—you Unleash.

When unleashed, the alien you are currently using enters a temporary state of hyper-evolution. For example:

This mechanic encourages aggressive, high-risk gameplay. The longer your combo streak, the faster you can unleash ultimate devastation.

Developer: Griptonite Games
Platform: Nintendo DS
Genre: Beat ’em up / Action-platformer

The Legacy: From Ultimate Alien to Omniverse

Ultimately, the Ultimatrix was destroyed and replaced by the completed Omnitrix in Ben 10: Omniverse. Azmuth deemed the Evolutionary Function "immoral," as it simulated eons of suffering for living DNA samples. However, the legacy of "Ben 10 Ultimate Alien Ultimatrix Unleashed" lives on. It remains the most chaotic, powerful, and controversial gimmick in the franchise’s history.

For fans of action-platformers and Ben 10 lore, Cosmic Destruction remains the definitive way to experience that power. The game is a time capsule of early 2010s tie-in titles, but its core design—build a meter, unleash an evolution, solve a puzzle—still holds up as a brilliant translation of cartoon mechanics into gameplay.

3. Ultimate Echo Echo

The most tactically overpowered evolution. Baseline Echo Echo is a living sound wave. Ultimate Echo Echo compresses its entire species’ sonic power into a sleek, robotic, silver body. It can create solid sound "discs," fly via sonic propulsion, and unleash a Sonic Doom attack that creates an omnidirectional blast capable of shattering reinforced metal. In the game Cosmic Destruction, this alien is the ultimate crowd-control weapon.
