Kain Cobra

Read full description

Kain Cobra: Autogun Blaster is a 2D platformer roguelite shooter that mixes kawaii charm, 80s cyberpunk and a lazy anti-hero. In the year 20XX, the two most powerful protectors of Planet Blue have been taken to a trial by the Intergalactic Federation for mismanagement, as 97% of the population lives in misery. The federation sent an Alien invasion to reset the Planet button and, Kain Cobra, the son of Buxios the darkest force protector, has the mission to save them, save the planet, and maintain the New New World Order in balance, yes... the New New World Order. Thanks to Kain’s father, Buxios- the master of dark energy-, and his rival, Yaroth—the master of light—, 97% of the population lives in misery on Planet Blue. Now both are on trial by the Intergalactic Federation, which has sent an alien invasion to hit the reset button. Against his will, Kain steps up. His true motivation? Save everyone to keep things as it is while he chills in his penthouse and avoids doing actual work. Kain Cobra is an intergalactic journey full of neon colors, kawaii charm, sarcastic humor, and of course, guns. In this chaotic adventure, you’ll join Kain Cobra, a lazy anti-hero more interested in cracking jokes than saving lives. But hey, someone’s gotta deal with the alien invasion, and guess who is the least busy. Kain Cobra is a Casual Roguelite 2D Shooter Platformer, designed for Mobile and PC, blending simple controls with deep gameplay. Imagine Archero’s addictive progression system, Mega Man X’s control and beauty visuals, and Contra’s intense action—then add a protagonist that what he does best is sleep. The controls? So simple, even Kain himself approves: move with a joystick, jump, dash, and let auto-shooting do the work. Oh, and there’s the Mojo Bullet Time Shield, activated with his sassy vibe. Dynamic levels are packed with platforms and enemies that test your reflexes. As you progress, earn XP, choose between 3 perks, and hope for the best. Outside the chaos, customize Kain’s blaster with collectible stickers for unique power-ups and merge them for better ones. You’ll also have a Talent System with 12 skills to unlock. The Creative Direction is as wild as Kain’s personality: - 80s nostalgia (you know, neon makes everything cooler). - Oddly Kawaii characters and - Esotericism?! (better don’t ask). All wrapped in the Pixtor Art Style, a unique blend of pixel and vector art with vibrant gradients—created by our Art Director to look as eccentric as it sounds. The interface has halftone and Memphis patterns with big buttons so even ET couldn’t get lost. The sound makes you feel you’re in an 80s arcade with retro wave music and modern retro effects. Now, the story: Universe 777, Planet Blue. It’s a mess. Thanks to Kain’s father, Buxios- the master of dark energy-, and his rival, Yaroth—the master of light—, 97% of the population lives in misery. Now both are on trial by the Intergalactic Federation, which has sent an alien invasion to hit the reset button. Against his will, Kain steps up. His true motivation? Save everyone to keep things as it is while he chills in his penthouse and avoids doing actual work. So, let’s save the world... with guns. Lots of guns.

Seven Keys

Can you find all seven keys while the guardians protect them? If you love Sudoku but crave a new challenge, this logic puzzle is for you. You are an explorer searching old caves for hidden treasure. Deep inside the caves, an ancient order still holds. The floor is divided into rows, columns, and smaller chambers, like Sudoku. Each guardian follows strict placement rules. No guardian may appear more than once in any row, column, or chamber. Seven keys are hidden among them, beside two poisons. There are also seven ivies and two potions to help you. Sometimes an ivy transforms into a mushroom, a stronger ally. A potion can be used to transform poison into ivy or reset a skill cooldown. You have the skills to defeat the guardians, but you must act quickly. Use Guided Arrow to hit Frogs, Multiple Shot to strike Bats, Spike to crush Snakes and Scorpions, Smash to shatter Rocks, Meteor to burn Spiders, Blizzard to freeze Floods, Sleep Waves to put animals to sleep and Ivy Healing to restore all ivies health. Each skill is tied to a specific weapon. Choose wisely. Follow the pattern. Find the seven keys. The treasure awaits those who see the order beneath the stones. Sharpen your focus with every cave you explore. Download now and start your treasure hunt!
