Cyber Volleyball

Cyber Volleyball is a 2D volleyball battle game from a side-scrolling perspective, combining precise physics simulation, deep character progression, diverse enemy mechanics, and online multiplayer.Realistic 2D Volleyball PhysicsThe game uses a Unity-based 2D parabolic physics engine, fully simulating the effects of gravitational acceleration, object weight, air resistance, and friction on ball movement. Every bounce, deceleration, and collision with the court, net, and players is calculated in real time. The game implements a strict three-hit system following international volleyball rules, with visual UI feedback showing the current hit count. Two trajectory prediction lines—high and low—are drawn on screen to help you anticipate the landing point and make the best play.Diverse Characters and EnemiesThe game features over a dozen character types, each with unique AI behavior and exclusive skills:Main Attacker: Powerful spikes, the finisher in head-to-head battlesSetter: Receives and distributes passes, the core of offensive organizationMiddle Blocker: A versatile player skilled in both blocking and quick attacksLibero: A defensive specialist focused on receiving and diggingHunter: Possesses pursuit abilities, striking the ball with tremendous forceClaw: Instantly pulls the ball toward itself for surprise attacksShockwave: Generates a shockwave on spikes, knocking back opposing playersViolence: Spikes carry devastating additional effectsIce: Attacks can briefly freeze opponents, locking down their movementsEater: Swallows the ball and controls its movementBuilder: Creates obstacles in front of the net for blockingShooter: Charges up and precisely fires the ball at targeted positionsEach enemy requires different tactics to overcome, keeping every match fresh and engaging.Stages and Adventure ModeThe game offers multiple modes to choose from:Tutorial Mode: Learn the game's controls and rules step by stepPVE Mode: Challenge AI opponents of varying difficulty levelsPVP Mode: Local battles against friendsEVE Mode: Watch thrilling AI vs. AI matchesAdventure Mode: Conquer multiple stages and face increasingly powerful enemy combinationsThe stage system supports paginated browsing with 28 stages per page, each offering up to a three-star rating. As difficulty increases, some stages trigger special mechanics—such as making enemy players invisible—testing your reflexes and judgment. All stage star data is saved locally, so you can review your progress at any time.Character Card and Progression SystemThrough the card system, you can deeply customize your team. The game features two types of cards: Character Cards and Item Cards.Character Cards offer 9 upgradeable attributes: Size, Defense, Jump, Speed, Strength, Reaction, Spike Range, Dig, and Dash. Spend stars earned from stages to upgrade, with each point directly affecting your players' actual in-game performance.Item Cards provide various match effect bonuses, including:Increasing the maximum team sizeRemoving the opponent's first-touch effectDisplaying the ball's landing point predictionAdding a freezing effect to attacksMaking the ball lighter as hit count increasesStrategically combine cards to build your ultimate lineup.Online MultiplayerThrough the built-in lobby system, you can create or join public rooms to battle other players online. When creating a room, you can set a password, maximum player count, and visibility, with automatic matchmaking also available to quickly find opponents.Inside a room, you can freely choose positions such as Main Attacker, Middle Blocker, Setter, or Libero. The system checks for duplicate positions within the same team to ensure balanced lineups. Once all players are ready, the match begins immediately. The game uses a server-authoritative network architecture to ensure fair synchronization of physics calculations and match results. Real-time chat messages during matches allow you to communicate with opponents and teammates.Comprehensive Settings and CustomizationThe game provides a complete settings system, covering volume adjustment (independent control of Master, BGM, and SFX), display effects (glow on/off, customizable ball trail color gradients), key bindings (fully customizable keyboard controls), and mobile touch sensitivity adjustment. All settings are saved automatically and can be restored to defaults at any time. The game also supports one-touch toggling between fullscreen and windowed mode with F11.Dual-Platform Control SupportSupports both keyboard (arrow keys to move, spacebar to jump, J/K/L for actions) and mobile touch gesture controls. On mobile, swipe direction and length are recognized and mapped to different volleyball actions, letting you enjoy a match anytime, anywhere.Key Features Summary2D volleyball battles based on realistic physics simulationOver a dozen enemy types with distinct AI behaviors and skillsFive game modes: Tutorial, PVE, PVP, EVE, and AdventureDeep character card progression system with 9 freely upgradeable attributesItem card system providing rich strategic combinationsOnline multiplayer with room creation, matchmaking, and real-time chatComplete key binding customization and display effect settingsSupports both keyboard and mobile touch controls
