Neon Armada ⚓
A neon-styled Battleship game that runs in the browser: one HTML file, no install.
Features
- Four opponents: Easy, Medium, Hard and Expert. The Hard AI counts every way your ships could still lie.
- Hidden bombs: each sea hides 3. Hit one and you lose your next turn.
- Bonus shot: sink a ship and you fire again.
- Radar: a one-use power-up that counts hidden ship squares in a 3×3 area.
- Show AI thinking: a heat map of where the AI thinks your ships are.
- Online 2-player: create a room, send the 4-letter code to a friend and play over the internet (direct WebRTC via PeerJS, with an automatic backup connection through a public MQTT server for mobile data and strict networks).
- Expert opponent: plays like Hard and has its own one-time radar.
- Turn timer: an optional 10 seconds per shot. Too slow and you lose the turn.
- Achievements: 10 medals to unlock, from "First victory" to "Grand Admiral".
- Drag & drop setup: drag a placed ship to move it, tap it to turn it.
- Invite link: the host copies a link that fills in the room code for a friend.
- Replay of the finished game, saved ship layouts, win streak record.
- Neon theme, drifting waves, particle explosions, confetti, and sound and music made in code (Web Audio API).
How to play online with a friend
- Open the game and press Create room.
- Send the 4-letter code to your friend.
- Your friend types the code and presses Join.
- Both place your ships and press Start battle. The player who made the room fires first.
