Arena Battleplan · Mech Arena Tactical Planner

Reserve & META

2 tabs: META (curated mechs) and ALL (full roster).
Search input + role + rarity filters always visible. The RESET button (next to the rarity row) clears search + all filters in one click.
Click the ★/☆ on a mech card to add/remove it from your custom META. Stored in your browser.

Hangars

5 slots per side. ALLIES by default, ENEMIES below (collapsible).
Drag a mech from the Reserve into a hangar slot. 1 mech per slot.
Click ⋯ on a hangar header to open the actions menu: copy to a single slot (same side or other side), bulk-copy to ALL allies / enemies in one click, or clear the hangar.
Each side has a trash button to wipe all 5 hangars at once. An optional checkbox resets names to default.
The 5/5 counter next to each player name turns lime/yellow/orange/red as mechs get destroyed in the current phase.

Weapons

Toggle SHOW WEAPONS at the top of the Hangars panel turns the feature on/off. Default ON. Data is preserved when off.
Each mech can carry 2 weapons. The orange line under a mech shows the current load (e.g. EMR / Rai, or just Rai if both slots are the same).
Click that line to open the weapon picker. It has the same META / ALL tabs and filters as the Reserve. Search matches name and acronym. Star a weapon (★) to add it to your custom META.
Use the Slot 1 / Slot 2 toggles at the top of the picker to choose which slot(s) your next pick writes to. Both ON by default — perfect for equipping the same weapon in both slots in one click. The trash icon clears the currently-selected slots.
You can also edit weapons via the pin inspection card (click a placed pin on the map).

Map placement & pin inspection

Drag a hangar mech onto the map to place it. Drag a mech from the Reserve onto the map for an ad-hoc enemy (auto-numbered E1, E2…; numbers reused when freed).
Drag any pin to reposition it. Its arrows follow.
Click a placed pin to open the inspection card: mech identity, weapons (slot 1 / slot 2 — click to edit), and contextual actions.
Actions on the card:
- Mark destroyed — flags the mech as destroyed for the current phase. Hangar chip greys out with a red slash. (Ally / enemy only.)
- Back to hangar — removes the pin from the map. The mech stays available in the hangar.
- Remove pin — only on ad-hoc pins. Drops the pin entirely.
The legacy × on pin hover still works (same as Back to hangar but it also marks destroyed for ally/enemy pins).

Arrows

Mech arrow: hover a pin → mousedown on its orange halo → drag → release on the destination. Color = player slot. Dashed. Anchored to the source pin (move the pin and the arrow follows).
Free arrow: click FREE ARROW, then mousedown on the map and drag. Solid line. Click the button again to cycle color (lime → black → red).
Delete an arrow: hover → red × at the midpoint → click. For free arrows the same popup lets you cycle color.
Double-click an arrow head: moves the source mech to the destination and removes the arrow. Mech arrows only.
Bulk move: the cyan ⇢ button in the map toolbar moves every mech with a single arrow to its tip in one click. Mechs with multiple arrows are skipped (listed in a dialog).

Beacons

Click BEACON, then mousedown on the map and drag to size the marker. Release to commit. Esc cancels.
Drag a placed beacon to reposition. Hover for: ↻ swap color (ally ↔ enemy) · ⎘ clone with same size · × delete. ↘ bottom-right corner = drag to resize.
Beacons are per-phase and propagate with the phase auto-clone.

Phases

3 phases. Each is a snapshot of placements, arrows, beacons, destroyed-state and footer note.
First visit auto-clones: opening Phase 2 (or 3) for the first time copies the previous phase as a starting point. After that, phases are independent.
The CLEAR PHASE button wipes everything in the current phase. Its ▾ menu offers granular options: clear only mechs / mech arrows / free arrows / beacons, or reset the phase to a fresh copy of the previous one.
Each phase has its own footer note, preserved through clear/reset operations.

Undo / Redo

Ctrl+Z undoes the last action. Ctrl+Y (or Ctrl+Shift+Z) redoes it. Buttons ↶ / ↷ in the map toolbar do the same.
History capacity: 20 actions per session. New actions clear the redo stack.
Undo can jump across phases if your previous action happened in a different phase. The phase tabs sync automatically.
History is cleared on map change, reset map, reset all, and backup import.

Backup & restore

Backup icon in the header opens the Backup / Restore dialog.
Export: download a JSON file with your hangars (allies + enemies + names), weapons assignments, the SHOW WEAPONS toggle, your custom META (mechs and weapons), and the strategy name. Phase data is intentionally not included — backups capture team setups, not match plans.
Import: pick a previously exported JSON. The dialog shows a summary and lets you choose, via checkboxes, which sections to import.

Layout & sharing

Toggle the side panels via the toolbar buttons (◀ R / H ▶), the panel chevrons, or the edge tabs when collapsed.
⛶ in the header for fullscreen.
SHARE generates a URL with the full plan (hangars + weapons + phases + destroyed-state + strategy name). Recipients open the URL in their browser and can fork without affecting yours.
Optional strategy name: set it in the SHARE dialog. It appears under the map title and in the browser tab.
The Unsaved indicator next to SHARE appears when your work isn't preserved anywhere outside this browser tab. Click it for save options.

Maps

Click the map title in the toolbar to open the map selector. 13 CPC maps available (3 with 3 beacons, 10 with 5 beacons).
Filter by mode, beacons count. Live search by name. RESET clears all filters.
Current map highlighted with an orange border and an ACTIVE badge.
Switching maps resets the plan: all placements, arrows, beacons, notes, destroyed-state are cleared. Your hangars, weapons and META are kept.
Pin and arrow sizes scale automatically based on each map's dimensions.

Local data & reset

Saved automatically in your browser: hangars (mechs + names), weapons assignments, the SHOW WEAPONS toggle, custom META (mechs and weapons), last-used map.
Not saved across reloads: phase content (placements, arrows, beacons, notes, destroyed) and the strategy name. Use SHARE to capture the full plan as a URL.
Opening a share URL (#s=…) does not auto-save: your edits stay in this tab. The Unsaved indicator will appear.
RESET ▾ in the header offers:
- Reset map — empties all phases on the current map. Hangars, weapons and META are kept.
- Reset all saved data — wipes everything from your browser (hangars, names, weapons, META, last map, phases). Cannot be undone; export a backup first if needed.
The help opens automatically on first load. Tick Don't show this on page load below to silence it.
A What's new dialog opens automatically once per new version. Reopen any time via View changelog below.
