“Aqua Kitty-Milk Mine Defender is a cute little arcade shooter that is too good to pass up. The graphics are pretty, the music is awesome, and it felt appropriately difficult on its own merit rather than me fighting the system. I’ve got little but praise for this game and felt it worth the price.”

About This Game

Aqua Kitty is a fast paced retro styled submarine arcade shooter with optional 2 player local Co-op.
Blast through hordes of mechanical sea monsters in your kitty sub and defend the deep sea milk mining kittens!


Due to a sudden shortage of milk, cats around the world are forced to seek out new sources to get their fix.
You and your team of milk mining kittens have overcome a fear of water to drill down under the ocean seabed and begin extracting vast reserves of what seems to be naturally forming full-fat milk.
Get ready for fast paced submarine action, defending the kittens from disruptive mechanical sea creatures.

Key Features

Optional 2 player local CO-OP.
Branching map progression of levels.
3 Main Game Campaign Modes
Normal Mode - the standard game of branching levels full of mechanical enemies with differing behaviours.
Easy Mode - a version of Normal mode in case you found it too hard, with more health and easier enemies.
Arcade Mode - a special survival mode where you must collect gems to purchase powerups.
Depth based power-up systems which gives partial control on the type and location of the power-ups created (allowing tactical advantage).
Classic infinite mode milk-free level, that never ever ends - for the hardcore challenge.
Dual firing submarine with a rechargeable secondary weapon that needs to be managed carefully (upgrades through game progress in Easy and Normal Modes, but upgrades via a shop system in Arcade Mode).

Development history

Hello, here is a short history of this indie games' development which we hope will be of interest.
Aqua Kitty was made by a core team of two people with audio created by Electric Cafe and the game box art by artist David Hankin.
It began as a small modern-retro styled PC game, designed to run at a crisp 1280x720 it was created with a love of the 16bit gaming era and late 80s video arcade games.

There are 3 core versions of the game available of different hardware - PC, XBox360 and Sony PSM.

Sony version is the oldest and smallest version. A critically acclaimed launch title for PSM (Vita).

XBox version is the Sony version with extra added levels + enemies + refinements.

PC version is the most feature rich and improves on the XBox one with new Weapons + Gradius style Arcade mode + yet further refinements and extra details (with the Steam version being unique in having online leaderboards and achievements).

All the new things we have added to the Steam version will also be rolled back into the other PC versions unless Steam specific (ie Online leaderboards, achievements, trading cards are STEAM ONLY).

Aqua Kitty is a shoot-em-up that’s heavily inspired by the old arcade game Defender, which I’ve played quite a lot. Basically, you shoot down waves of enemies while protecting your kittens from being abducted, while making heavy use of your radar. It’s a fun game, but it feels a bit repetitive. Some more variations between the levels would have been nice. Maybe some more bosses or environmental hazards.

But still, it’s a retro shoot-em-up about cats. That’s enough to check it out.
The survival mode is also quite addictive, and has been keeping me busy.

If you can remember 'Defender' as a kid you are more than half way to understanding what 'Aqua Kitty - Milk Mine Defender' is about. If by any chance you aren't so long in the tooth as some of us grandads of gaming are? heres a basic run down. First of all you don't need to be a grandad to enjoy this Kitty themed take on Defender, as it has this back to the basics timeless gameplay, sceams retro but in a revamped modern way, that many retro games fail to do.

Its has bases with milkminers at the bottom mining for milk, they would rather go about their biz without being abducted by robot jellyfish. This is where you come in as you protect the miners from numerous seabeasts with fiery justice! In your seasub you have normal fire, missle and the ablity to turn about to go left or right. The map at the top is a 2D view of the sea going left and right. You can travel in circles by reaching the far end of either left or right. The map plays a very important part in the defence of the milkminers as it can give the local of each, (red dot abducter jellyfish), (white dot normal robot fish), (yellow power-up) and lastly the local of the milkmine. I think that about raps it up?

If by any chance you don't like reading I've put a sentence summing up Aqua Kitty
Aqua Kitty - Milk Mine Defender is a beautful, colourful 16-bit pixel style defender game that pays homage to retro gaming with a sound so fitting the style. Its that good!

I recommend this title at full asking price.

A really fun homage to Midway's arcade classic Defender. It's a really slick shmup that delivers on it's classic namesake with tight gameplay and a fun presentation.

Yes, yes, a thousand times yes, this game is everything right with retro indie game developers.

If it wasn't clear, this game is essentially the old classic Defender, with some modern shmup twists and oh my GOD that soundtrack is amazing. All of those adorable pixel cats don't hurt, either.

Pick this up if you can afford to, it's a wonderful game.

Aqua Kitty Milk Mine Defender 8/10

a vary nice looking, cute and awesome sounding 8-bit arcade shooter, i really like how the animations are done as well, controls are good its a little sluggish but fits with how the game plays its a good buy at 6.99 and has vary cute perrrsonality.
difficulty is vary high many kittens will perish to acquire that precious milk :(

*****Recommendations for the Developers*****
i really think the level of spawns needs to be tweaked in Infinite Espresso level i have not done all the normal levels yet and i hear you tweaked some of them already but in Infinite Espresso level it gets too much absolutely no room to move with the amount of enemies and bullets and this is at wave 11 it would be nice to see some tweaks so we could have some fun with it we should be able to run longer in that mode (easy, hard and a tweaked Arcade mode).

Arcade mode needs to have lives i think it just does not seem doable or fun and yes i am aware of the perrmanent upgrades 9 lives makes sense i think :P game is hard as hell after all.

weapon variety seems lacking i have some ideas, slower firing explosive torpedos, seeker torpedos. i think you could replace the X or Y button for an added heavy weapon (aka torpedos idea) or defence explosive or shield on top of the other heavy weapon too but just one of the X or Y buttons so you can still Purrrchase power ups think about it ;)
