It’s the question that has haunted every kid on a playground since 2009. You’re playing through the campaign, you've unlocked Big Chill, Humungousaur, and Spidermonkey, but then you look at the box art. There he is. Alien X. The Celestialsapien. The guy who can blink and recreate the entire universe. Naturally, you want to play as him. But if you’ve spent any time with Ben 10 Alien Force Vilgax Attacks Alien X content, you know the crushing reality.
He’s not there. Not really.
I mean, he's in the game. He shows up in cutscenes. He’s a major plot point. But as far as a playable transformation goes? You’re out of luck. It’s one of the biggest "gotchas" in licensed gaming history. People spent hours scouring the internet for cheat codes or secret unlocks, hoping there was some hidden way to play as the most powerful being in the franchise. Honestly, the disappointment was real.

The Alien X Problem in Vilgax Attacks
Let’s be real for a second. If the developers at Papaya Studio had actually made Alien X playable, the game would have been broken in five seconds. Think about it. Ben 10 Alien Force Vilgax Attacks Alien X is a game built on platforming, light puzzles, and beat-'em-up combat. If you have a character that is literally omnipotent, why are you jumping over pits on Vulpin? Why are you punching DNAliens? You’d just wish them out of existence.
From a game design perspective, Alien X is a nightmare. In the show, Ben can’t even move when he’s Alien X because he’s stuck in a perpetual debate with Bellicus and Serena. Capturing that "immobility" in a fast-paced action game like Vilgax Attacks would have been boring. Capturing his "power" would have made the game too easy. So, the developers made a choice. They turned him into a plot device.
The story of the game basically kicks off with Vilgax invading Earth. Ben tries to use Alien X to stop the invasion right at the start, but—classic Alien X—Bellicus and Serena won't cooperate. Ben gets stuck. Professor Paradox has to show up to save the day, and Ben ends up losing most of his aliens. It’s a convenient way to reset the player’s power level, but it feels like a bit of a tease when you see that silhouette in the UI.
Why Fans Keep Searching for a Playable Version
You’ve probably seen the YouTube thumbnails. They’ve got bright red arrows pointing to a modded PC version or some "secret" cheat code that supposedly unlocks the Celestialsapien. Most of these are fake. Back in the day, the rumor mill for PSP and PS2 games was wild.
- Some players claimed if you beat the game on the highest difficulty without dying, he’d appear. (False).
- Others said there was a specific button combo at the title screen. (Also false).
- There were even rumors about a "V-Force" edition of the game that had him as a bonus. (Complete myth).
The truth is that the game's code just doesn't support him as a combatant. If you look at the game files on the PSP version, there isn't a moveset for him. There isn't a 3D model with hitboxes designed for fighting. He is a cinematic asset. It's kinda funny how much effort we put into finding things that don't exist, isn't it? We wanted that power trip so badly.
The Role of Alien X in the Story
Even though you can’t control him, Ben 10 Alien Force Vilgax Attacks Alien X uses the character to set the stakes. The game takes us across several planets—Bellwood, Vulpin, Terradino, Encephalon, Anur Phaetos, and MorOtesi. Throughout this journey, the looming threat of Vilgax’s Null Void projector is the main focus.
Alien X represents the "Easy Button" that Ben can't press. It adds a layer of frustration to Ben’s character that actually mirrors the show pretty well. You feel Ben's annoyance because you, the player, are also annoyed that you can't use your best weapon. It’s a rare moment where player frustration and character frustration align perfectly.
The game ends with a confrontation where the Omnitrix is recalibrated or fixed, but even then, the focus remains on the core ten aliens. The "Alien Force" lineup was always meant to be the star. Adding an eleventh, god-tier alien would have overshadowed the utility of characters like Swampfire or Jetray.
Comparing Vilgax Attacks to Other Ben 10 Games
If you really want to play as Alien X, you have to look elsewhere. Vilgax Attacks was the second Alien Force game, and it improved on the first one in almost every way. Better graphics, more planets, and a more coherent story. But it stayed "grounded" in its mechanics.
- Ben 10: Cosmic Destruction: This is where things changed. In this follow-up, Alien X actually makes an appearance as a playable character, but only in a very specific, limited capacity (usually as a finishing move or a brief power-up on certain platforms).
- Ben 10: Omniverse Games: These later titles finally leaned into the "bloated" roster, giving players dozens of aliens.
- The Reboot Games: These are much simpler and don't really capture the scale of the Alien Force era.
Vilgax Attacks remains the favorite for many because of its atmosphere. It felt like a grand space opera. Visiting the home planets of the aliens was a genius move. Seeing the Vulpimancers on their own turf or navigating the jungle of Terradino gave the world depth that the TV show couldn't always explore due to budget.

Technical Limitations of the PSP and PS2 Era
We have to remember the hardware. The PSP and PS2 weren't exactly powerhouses by 2009 standards. Most of the memory was taken up by the multi-planet environments and the transformation mechanic itself. Swapping models on the fly is taxing on RAM.
Every time you hit that R1 button to transform, the game has to quickly load the new model and its animations. Adding a character with the visual effects of Alien X—the shifting stars, the translucent body—would have been a technical hurdle. It’s likely the devs decided that the "juice wasn't worth the squeeze." They prioritized making the core ten aliens feel distinct and fun rather than spending a huge chunk of the dev cycle on one guy who would fundamentally break the game’s difficulty curve.
How to Actually "Experience" Alien X Today
Since you can't play as him in the vanilla version of Ben 10 Alien Force Vilgax Attacks Alien X, what can you do?
Actually, the modding community has stepped up in recent years. If you’re playing on an emulator like PPSSPP, there are texture swaps. You can basically skin a character like Chromastone or Alien X to look like him, even if they don't have his powers. It's a cosmetic fix, but for some, it's enough.
Also, it’s worth revisiting the boss fights in Vilgax Attacks. The fight against Albedo or the final showdown with Vilgax are high points for the series. They require genuine strategy and switching between aliens to exploit weaknesses. If you had Alien X, you'd miss out on that tactical gameplay. You’d just stand there and win.
Actionable Tips for Completionists
If you are going back to play Vilgax Attacks in 2026, don't waste your time looking for the Alien X unlock. Instead, focus on these actually achievable goals to get the most out of the game:
- Maximize your Alien Forms: Collect all the gold Sumo Slammer cards. They aren't just for show; they are essential for upgrading your aliens' combos and health.
- Master the Quick-Switch: The best players don't stay as one alien. Use Jetray for mobility, then mid-air switch to Humungousaur for a ground pound. That’s how the game is meant to be played.
- Explore the Home Planets: Don't just rush to the objective. The level design in Vilgax Attacks has a lot of verticality. Use Brainstorm’s electricity puzzles to find hidden health boosts that are tucked away in the corners of the map.
- Watch the Cutscenes: Honestly, the voice acting is top-tier because they used the original cast from the show. Yuri Lowenthal (Ben) and James Remar (Vilgax) kill it. The dialogue regarding Alien X's "refusal" to help is actually some of the best writing in the game.
The legacy of Ben 10 Alien Force Vilgax Attacks Alien X isn't about what’s missing. It’s about the scale of the adventure. It took Ben off Earth and showed us the galaxy. Even if we didn't get to play as the strongest alien in the universe, we got to feel like a hero who had to work for his victory. That’s a much better game anyway.
