Description

Gradius III delivers brutal side-scrolling shooter action where precision, timing and the classic power-meter define survival. Players pilot the Vic Viper through sprawling stages filled with dense enemy patterns, environmental hazards, and towering bosses that demand memorization and split-second reflexes. The arcade original is remembered for its relentless difficulty, punchy synth soundtrack, and satisfying power-up chains that let skilled pilots tailor their loadout. Each run rewards pattern recognition and careful resource use; mistakes are costly, making arcade sessions tense and memorable. Ideal for fans of old-school shooters who enjoy steep challenges and cathartic boss encounters.

    Make sure you open the same game as the host.
    Click Netplay, then select Join Room from the room list and join the desired room.

⚠️ Note: Netplay works best when all players use the same game version and have a stable internet connection.

Controls:

For the best retro experience 🎮, a gamepad is recommended. You can customize controls in the Settings Menu.
Note: Press any button on your gamepad so the emulator can detect it.

🕹️Gamepad compatibility:

  • Xbox-style (XInput): Works best on most browsers and devices.
  • PlayStation DualShock / DualSense: Supported on many games, but button mapping may vary depending on the game, emulator core, browser, and operating system.

🕹️Recommended browsers:

  • Chromium-based browsers (Chrome, Edge, Brave): Best performance and controller support.
  • Safari (macOS / iOS): Good support for Bluetooth controllers.
  • Firefox: Not recommended for gamepad play due to inconsistent controller mapping and limited Gamepad, Sound API behavior.

🕹️How to set up controls:

  • PC (Windows / macOS): Connect your controller → start the game → SettingsControls → map buttons.
  • Android: Pair via Bluetooth or USB-OTG → launch the game → SettingsControls.
  • iOS (Safari): Use a compatible Bluetooth controller → open the game → configure controls in the Settings Menu.

💾 Save & Load Guide

Don't lose your progress! You have two ways to manage your game states:

  • Auto-Save (Browser Storage): By default, your progress is automatically saved to your browser's local storage. You can pick up right where you left off the next time you visit, provided you do not clear your browser cache.
  • Manual Save/Load (Export to File): For maximum safety and playing across different devices, you can export your save data:
    1. Open the Settings Menu in the emulator.
    2. Select "Save State" to download your progress as a file (usually .txt or .state) to your device.
    3. To resume, simply use "Load State" and select that file to continue playing.

⚠️ Note: We highly recommend exporting your save file frequently to avoid losing data due to browser updates or accidental cache clearing.
