How Do You Unlock All Aliens In Ben 10 Ultimate Alien Cosmic Destruction?

So long as you’re looking to 100% the game, Ben 10 Ultimate Alien: Cosmic Destruction features a roster of many popular Ben 10 aliens that can be unlocked in the game by completing various sections of story and hunting down many secrets throughout the levels. Some aliens like the well known Humungousaur and Echo Echo are even story locked, meaning that they must be acquired by progressing through the game’s story. The destructive yet fun to unlock Jetray for example can be found by breaking through certain walls throughout the later levels of the game. I discovered Jetray’s hidden unlock behind a suspicious wall in ‘High Speed Havoc’ for example.

Wild Card: Chromastone. One of the aliens is to be found by defeating Zombozo in ‘Circus of Fear’ – a side mission which isn’t linked to the main storyline so it’s easy to miss. However the battle with Zombozo is quite dramatic, especially as his clown appearance contrasts with the new alien who is a mass of crystalline structure – smoking, metallic and glowing. Also, ‘Alien Collector’ is a fun little minigame that can be played to collect a load of new upgrades for your unlocked aliens.

Unlocking all the aliens in 'Ben 10 Ultimate Alien: Cosmic Destruction' is pretty much a puzzle which can be solved with exploration and experimentation. There are some aliens you can get straight off the bat, such as Swampfire and Big Chill. However, others are unlocked by completing specific tasks. To unlock Way Big for example, you have to complete the ‘Titanic Trouble’ mission in the main story, which in itself is quite a grind, but its worth it when you can finally become the huge hero, Ben 10.

There are a few others including Lodestar and Nanomech. As previously mentioned, Lodestar can be unlocked by completing the ‘Magnetic Personality’ side quest, and to unlock Nanomech, you have to search for all the Nanite Chips throughout the game. It’s kind of tedious but once unlocked, it adds some replay value. I personally found Ampfibian to be pretty cool. The way he was unlocked was a tough platforming section in the ‘Shock It to Me’ mission, and it’s nice to be able to use his electricity to blast away enemies like an electric eel.

You really have to work to get every alien in the game, which is half the fun. As I previously mentioned, characters like Spidermonkey and Goop are unlocked as you progress through the story. But the hidden ones in the game are so cool. To unlock Brainstorm, you have to complete all of the 'Psionic Puzzles' in the 'Mind Over Matter' mission. The puzzles are a real headache (literally), but the head twists and and electric shocks are all worth it in the end to use his psychic attacks.

Revisit past levels to use your new alien in new and creative ways to reach places you couldn’t before, such as Big Chill’s ability to fly, to reach the top of the Arctiguana frozen lair for example. Arctiguana can be unlocked by defeating Vulkanus in a mini-boss fight, as noted earlier. The levels and missions are designed to allow for lots of replayability, so be sure to explore every nook and corner of the game. With a full Omnitrix, my last playthrough took an exorbitant amount of time to complete because of all the backtracking to collect all of the secrets the game had to offer.
