Common Questions
Frequently Asked
How does saving work?
Progress saves to your browser automatically. Mount a folder and it writes netbattle-save.json directly to your device after every battle — with a save icon, like a real console game.
Can I connect an AI to my Navi?
Yes, optionally. On the AI Identity page, enter your own Gemini, Claude, or OpenAI API key. Your Navi gets a real conversational personality. Keys are stored locally and never sent to our servers.
What kind of game is it?
A tactical grid-battle RPG — a spiritual successor to the classic network battle genre. You build chip folders, customize your NetNavi, play story chapters, and battle viruses on a 6×3 grid.
Does it work on mobile?
Yes — any modern browser on phone, tablet, or desktop. Folder mounting for local saves requires Chrome or Edge, but localStorage saving works everywhere.
What is Story Mode?
Story Mode features multiple campaigns, each broken into chapters with a full synopsis, main story events (unlocked after completion), mission objectives, boss battles, and collectible key items.
Ready to Jack In?
