Faces are solid to ships; shots pass OUT in the arrow direction only. Mortars fly over.

Round goal pads receive NEUTRAL flags (no own flag required).

Right-click any cell removes items there (or clears the tile to void if empty).

Optional per-map tuning. Sliders left at default are not saved — the map uses the server's standard settings.

Load any live map to study or remix it. When your map is ready, use EXPORT and send the .json to a server operator to get it into the rotation.

Classic .MAP files from the original game convert right in the browser — review, repaint fortified @ cells with real bunkers where wanted, then export.
