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.
