About This Game


This is a competitive 3D shooting game based on crustaceans.

Yes, you read that right.

You get to control unique creatures like lobsters, crabs and barnacles, in a wild water world that exceeds all human sense.

Experience intense battles that take place in “NEO AQUARIUMS,” dimensionally linked aquariums that promote the evolution of organisms, and use skills that are unique to arthropods, such as “molting” and “self-amputation.”

You can even customize your own aquarium by placing the small creatures and pieces of terrain you earn in battle. Use your wild nature and your strategic skills to become the King of Crustaceans!

Game Modes

- Story Mode
In this mode, you battle all kinds of aquatic creatures while enjoying the tantalizing story.

- Free Battle Mode
You can play local competitive multiplayer for up to 4 players using split-screen, or you can battle online via Steam network.

- Aquarium Edit Mode
Here you can use the parts you earned in Story Mode to customize your own stages. The creatures you place will come to your aid during combat.

Message from the creator

Have you ever really looked at the crawfish and crabs you eat so casually every day?

Their hard shells, their sharp claws and spines, their 10 legs that they can amputate in case of emergency, their compound eyes that allow them to see in all directions...

They are beautiful fighting creatures, shaped by nature to survive with only their bodies in the hostile environment of the deep sea.

In most video games, human beings shoot lasers and fly through the sky as if it’s nothing, but I asked myself the question: “What if lobsters and crabs had these kinds of powers?”

Nature’s strategies sometimes far exceed the creativity of humans.

If you reach a deadlock in the human struggles of your daily life, try turning your eyes towards nature; I’m sure you’ll find quite an unexpected battle for survival there.

-Awesomely goofy concept
-Entertaining attack styles and special moves
-Each character has their own quirks and playstyles
-Plays like a 1 on 1 mech fighting game, but with crustaceans

-Tends to crash when a certain character uses their strongest attack (at least in my experience; other players report crashing at seemingly random intervals)
-Tutorial is nigh nonexistant and the manual is obtusely written, making learning the game more difficult than it needs to be
-Controls are clunky and take quite a bit of getting used to (using an XBOX360 controller is highly recommended)
-Multiplayer is as dead as dead can be, and the matchmaking is incredibly basic (no private lobbys, no dedicated servers, etc.)

No explanation of the mechanics.

Terrible Controls.

No idea how to unlock the other more awesome crabs.

Barnacle is OP.

Still a lot of fun.

Several things to take note of:
The game language is initially set to Japanese. This can be set to English in the options menu.
The devs went out of their way to set initial language to English in an update! How nice.

This game is certainly an anamoly. It's a 3D bullet hell versus game with, uh, crustaceans as the combatants. I'm jumping on reviewing this because I was really pleasantly surprised.

The devs have it down to a point in the description; these are creatures we eat so casually, yet underwater, they are some of the most inclined to fight with one another over mates within their own species, even for food amongst other crustacean species. I mean, look up a crab and lobster fighting. It's some interesting stuff.

And I believe that is perfectly captured in this game. Just with the addition of lasers and bullets being shot out of their eyes and energy claw attacks and what not. I can see that there was love put into this thing; the Snow Crab, for instance, can only move "forward" by turning sideways first.

I really wouldn't dismiss this as one of those one-off funny games just because of that, though, there is some depth and rhyme and reason to it, which I will do my best to describe.

A big part of the game is the fact that a majority of the crustacean fighters can sustain limb damage. Using the example of the Snow Crab once more, for instance, you can lose all of your legs and thus, experience a reduction in speed. The only way to circumvent this is to spend accumulated meter points to shed your skin and gain all your limbs back. During this maneuver, you're very vulnerable upon coming back anew. You can also self-mutilate yourself while you attack, either ranged or melee, to make your hitbox smaller or for some mad hit and run tactics.

Another feature of the game is the weakpoints of each of the fighters. Take the Hermit Crab, for instance. It cannot be damaged at all if hit in the shell they hide in. It can be broken, but you better take care of the thing before it finds another shell (think Cody's knife from Street Fighter). Thus, knowing your crustacean match-ups will lead you to AQUATIC VICTORY.

Each arthopod also possesses a differing movesets, each having unique ranged and melee attacks along with charged attacks that take meter to use. Meter is accumulated by hitting and by getting hit. Careful management of meter is central in this game, I find, as you'll be a sitting duck if you lose your limbs and don't have the meter to regenerate.

After fights you also get aquarium parts, which are not only for asthetic, but can also help you in upcoming fights. Starfish, for instance, spin around like a damn rapid spin Staryu to do some chip damage. Very nice touch, although I never really touched this feature.

The music is also gloriously manic, quite fitting for this game, honestly. You can go from some smooth jazz and traditional Japanese instrumentation as you shoot lobster lazers at barnacles to some Japanese vocal rock when you fight some of the later opponents in the "story mode". It's great.

The game is a bit lacking in giving a tutorial, but with Assassin's Creed-esque button prompts that tell you what each button does when you press it, which can be turned off at any point, it should be more than enough. The controls in of themselves can be a bit finicky at first, too, especially with the crabs in particular that can't conventionally move forwards, but it's something that I got used to, especially after taking note of things such as water current affecting your movement.

I can heartily recommend this game as both a novelty and as something functional and fun. Definitely something to laugh with your friends about. There's online multiplayer too, which I haven't delved into myself. If you're not sold and the mechanics don't interest you, however, I'd say to wait for a bigger price drop, but I'm having a lot of fun with this thing myself, and it should keep you busy for a while with several difficulties, achievements and unlockable... characters.

This is easily my favorite lobster-based battle game. It features a compelling storyline that will be sure to something something. Lobsters. Regardless of the gripping story, the game mechanics are finely tuned to sate my super hardcore MLG gamer appetite. I strongly recommend you DON'T get this game because you're most likely a pansy and think lobsters look gross or something. Get on my lobster-level and don't forget the butter.

Underwater Crab Battle game orginally released in 2011.

Plays sort of like a senko no ronde or virtual on.

The graphics look pretty nice, and it has some insanely good music.

Controls well with a controller, did not try with kbm

Ran into no technical issues, and net play worked well enough.

The language defaulted to Japanese for me, but you can swap it to english in the options menu. The cutscenes are pretty funny, not sure if that is from the localization.

Would highly reccomend, keep your eyes out for NEO AQUARIUM 2

Also here is a tier list based off matchups:

Corn Barnacle

Spiny Lobster
Mantis Crab (Squilla)

King Crab

Red Frog Crab
Hermit Crab
Snow Crab

Wtf did you really pick Mevious tier

Not often is there a game that can tickle your funny bone at the same time as being enjoyable.
-Fast paced action
-Interesting subject matter and background story
-Beautiful art (Graphical design dated to circa 2008)
-Ability to make your own maps

-Repetitive gameplay
-Attacks feel weak
-Issue with balance of characters

-Controls take some getting used to

Gameplay depth is limited, and fitting to experience this game in short bursts. After 1-2 hours most of the essential dynamics will be evident, and gameplay becomes repetitive. After several matches, the ideal combination of (characters and items) becomes evident. Subsequently, each match will resemble the prior after you have figured out the correct mix.

Background story and subject matter are unique, interesting and humorous. I will not go in-depth into this feature as to avoid spoilers. The basic gist regards a new technology which allows humans to use sections of the oceans as aquariums. As a result, crustaceans evolve into bad-♥♥♥ laser shooting beings which, for some reason still cant figure out how to stand up right. The graphics, although not perfect, do justice to the unique story and subject matter with an appropriate tone and style.

Overall, characters are well balanced, each with particular strengths and weaknesses. These traits usually balance each other out. However, in the case of the Barnacle, it's increased firepower overcompensates for its reduced mobility; which makes it an overpowered class.

Aiding replayability, the game contains a "Create a map" mode where you can customize your aquarium, and choosing the location for flora and fauna. The animals will aid you during battle by shielding you, shooting lasers, etc. This adds some depth to the gameplay, as you can use the (money/points/credits) you gain on each match to purchase more offensive or defensive assistance.

This is not a game with a long shelf life, but it is a fun game as you discover the different dynamics, characters, offensive and defensive mechanisms and their optimized combinations.

As a final verdict I give it 7/10. In all truth you wont play this every day but during the time that it is played it is very fun and has about the same value as a movie. This is a sometimes food but a good sometimes food it is. Overall, this is a fun little game that will set you about the price of a movie ticket and will entertain you for at least as long. Some games are better enjoyed in small doses, this is one of those.

What is man in nature? A nothing in relation to infinity, all in relation to nothing, a central point between nothing and all and infinitely far from understanding either. Without beginning or end, crab stretches on into infinite.

Holy ♥♥♥♥.
This game is something else.

You'll spend about 30-45 minutes trying to figure out how to move your crustacean in as straight a line as possible, to find you're still clueless as to what the other controls actually do. The game comes with labels of what button does what, at least, but no explanation of mechanics behind them. It gets worse. Don't jump straight into campaign whatever you do, practise on freemode to learn the basics, because trust me:

All ♥♥♥♥ing hell breaks loose.
Pitted against my first opponent, it becomes intense VERY fast when lasers shoot out of your enemies crevices in all directions, performing nautical manuevers on a dogfighting equivalent, as I struggled to barely hobble my lobster in its general direction. And then the ♥♥♥♥ing scenery starts attacking you.

You are given literally no explanation of why anything happens in this game, you aren't told why you have the ability to fling your legs at the enemy, or what the control function actually does, or what POW even stands for, I don't even know at this point what 'Oxygen' or 'Organic matter' does in the game.

Some things you that may help you first off;
~ Holding down 'C' then pressing either Z or X detaches your melee and ranged limbs. HOWEVER, what the game doesn't explain is that they can still function and be used remotely, and have strategic uses.
~ The scenery, as I mentioned earlier, can be your ally. The coral, leeches, sea slugs, starfish, those weird giant shrimp things, can be recruited to your team by holding 'C' in their vicinity and will proceed to attack your opponent. This can even be used to recruit your enemy's following.
~ During the campaign, you unlock more placeable scenery, which can be added to your side of the Aquarium by pressing space and entering the Aquarium editor. This is extremely useful in the later stages of the campaign, otherwise you'll get your ♥♥♥ handed to you by that ♥♥♥♥ing CPU Lobster.

Other than that, each Crustacean has their own movement and abilities you must learn in order to fight effectively, although this can be done in practise mode.

All in all, the game has alien controls that you'll be forced to become accustom to, almost no explanation of mechanics, and Crab claws that produce laser swords.

It's chaos in it's most beautiful and Crusty form. Buy the game, become the Crab King.

Playing NEO AQUARIUM in Japanese is by far one of the most intense gaming experiences I have ever had. The innovative game design is amazing and the gameplay intense. Never for the life of me did I think a crustacean based battle game could be so action packed and yet, highly rewarding on a deep emotional level!

Everything from the innovative game design, to the adrenaline fuelled battles just screams "well executed". Controls are a blessing from the heavens and super intuitive. Other devs could certainly learn from this.

Other than the stunning graphical detail and innovative gameplay and design, the games soundtrack is really something on its own! Rarely do you see tracks like these that well and truly immerse you into the game, whilst at the same time still managing to keep up with the almost mind-numbing action that the game provides. Eagerly awaiting soundtrack DLC!

The only downside is that the game language is, by default, set to English. Fortunately you can very easily change it to Japanese, to play it the way NEO AQUARIUM is supposed to be experienced. It's a pity that the devs decided to pander to the filthy Gaijins buying the game, but it is understandable decision in our modern globalised society.

Finally, I rate this game a solid 10/10. It's almost a pity I was gifted it during a sale, as it's easily the 9 Euro worth.
