Anode Heart: Layer Null is a role-playing card game with collectible elements, set in a multi-layered virtual world. The player controls Blank, a man lost among fragments of code, where emotions have long been replaced by algorithms, and each card represents a choice between reason and chaos. The Art of Survival in Code Gameplay is based on combining skills and reactions. Cards allow you to manipulate energy, override parameters, and alter combat logic in real time. By developing a strategy, the player decides whether their hero will become a hacker seeking freedom or a Shadow Operator, merging with the system for ultimate power. Each game is a new simulation, with no second chances. Progress is measured not by levels, but by the depth of your penetration into the network. The deeper you go, the more unpredictable the enemies become, each possessing their own data sets and logic. The cyberfantasy atmosphere creates the feeling that you're not just playing a game, but invading the mind of a machine that's studying you in return. Features of the game Combat system with energy management and time distortions. A collection of hundreds of cards with rare combinations and special properties. Character development through code merging and server architecture changes. Unique visual style inspired by GameBoy and PSX graphics.
