Deck viewer

The deck page shows a Broken Arrow deck card by card, checks it against the game's deck rules, and lets you share it as a link or, with your own game connected, open and save the game's .dek files. Worked out by this site

Getting a deck onto the page

A deck reaches the deck page as a link: the deck itself is written after #d= in the address, and your browser reads it there. Worked out by this site With no deck in the address, the page says "Open a deck link from your AI, or a .dek file, to see a deck here." Worked out by this site

A link carries a checksum, so a link changed in copying is reported as damaged rather than read as some other deck. Worked out by this site The page then says "This deck link is damaged. Copy it again exactly as your AI gave it." It also refuses a link that is "too long to be a deck", and one that comes "from a newer version of this site", for which it asks you to reload the page.

What the page shows

The heading is the deck's name. Below it, a summary gives the two Battalions and the deck's Total in points. Worked out by this site

The cards follow, grouped under Reconnaissance, Infantry, Vehicles, Support, Logistics, Helicopters and Aircraft. Each heading shows the category's "Slots" and "Points" used, against the caps the two battalions give it. Worked out by this site A category appears when it holds cards or the battalions give it slots. Worked out by this site

Each card shows the unit, linked to its page, its count, its Cost and its chosen options. A card with a transport adds "Rides" with the transport, its count and its options. Worked out by this site A card's cost is the unit and its options times its count, plus the transports and their options times theirs. From the game's code The page prices every card from this site's current data, never from a cost written in a file. Worked out by this site

A link made under an older game build adds a notice: "Made for game build" followed by the build, then a list of each card whose price has changed since, with what it was and what it is now, or a line saying no prices have changed. Worked out by this site

The rules it checks

The summary says "No rule problems found." when there are none. Problems with the whole deck or a category are listed there under "Rule problems", and a problem with one card is shown in red on that card. Worked out by this site "Warnings" are listed apart: things the game flags without refusing the deck. Worked out by this site

The page checks the game's rules:

• A deck is one faction with two different battalions of it. This site's owner checked this in the game's hangar; the game's code also needs two battalions to save a deck. Worked out by this site
• Every unit is in the current game build, belongs to the deck's faction, sits in its own Arsenal category, and is offered by one of the two battalions. From the game's data
• A card's count stays within the limit its battalion sets for that unit. From the game's code
• Each option belongs to the unit, one per part. From the game's data
• A transport must be one the battalion offers for that unit, and a card may not have more transports than units. From the game's code
• A deck holds each unit on one card only; a transport may serve several. This site's owner checked this in the game's hangar. Worked out by this site
• A category holds at most 7 cards, or fewer if the two battalions' slots for it add up to less. From the game's code
• A category's points may run up to 10% over the two battalions' points for it. From the game's code
• The deck's total may not pass its faction's maximum. From the game's code Below 95% of that maximum the game flags the deck as incomplete but still accepts it, so the page lists it as a warning. From the game's code

So a category heading can show its points above the cap without a problem, as long as it stays within that 10%. Worked out by this site Should a rule ever be unconfirmed in the game, the page adds a note that the check may still change. Worked out by this site

Airlift

When the deck holds helicopters or cargo planes, an Airlift section shows "What each helicopter and cargo plane in this deck can carry, one unit at a time." Worked out by this site This counts the transports riding on cards as well as cards of their own. Worked out by this site

Each entry gives the aircraft, its count, its seats and its heavy lift in kilograms, then the deck's squads and vehicles that fit it, with each squad's soldiers or each vehicle's weight. "Nothing in this deck fits it." means none does. Worked out by this site

• A squad fits when the aircraft has at least as many seats as the squad has soldiers. Worked out by this site
• A vehicle fits a helicopter when its weight is within the helicopter's lift. Worked out by this site
• A cargo plane drops what it carries, so it takes only air-droppable squads and vehicles. Worked out by this site
• A loadout option that changes a unit's seats, weight, lift or air drop is counted. Worked out by this site

Nothing is added up: the page shows each limit and leaves the load to you. Worked out by this site

Sharing a deck

"Copy link for your AI" copies the deck's link and turns to "Copied". If the browser refuses the clipboard, a field shows the link to copy by hand. Worked out by this site The link holds the whole deck, plus each card's cost when the link was made, so a later visit can tell which prices changed. Worked out by this site

Opening and saving .dek files

A .dek file is the game's own deck file, encrypted with the game's key. From the game's code Opening or saving one here needs that key. Worked out by this site Under "Connect your game", choose global-metadata.dat from your install, in your Steam library under steamapps\common\broken_arrow\BrokenArrow_Data\il2cpp_data\Metadata. The page finds the key in it; the file is read on your device and never uploaded. Worked out by this site The key is remembered on that device until you press "Forget my game key". Worked out by this site

Then "Open a .dek file" turns a deck file into a deck link and shows it, checked like any other. Worked out by this site "Download .dek" saves the deck shown as a file for the game, and only when it has no rule problems. Worked out by this site

Building a deck with an AI

The AI decks page, linked from the site's footer, shows how to connect Claude or ChatGPT to this site with its connector address. Custom connectors need a plan that allows them. Worked out by this site You then ask for a deck that suits how you play. Your AI looks up units, prices and rules from this site's data for the current patch, checks the deck against the game's rules, and gives you a link to the deck page. Worked out by this site Its numbers and rule check are the same ones this page uses. Worked out by this site To improve a deck, paste its link back to your AI, which can read it. Worked out by this site

Your AI provider sees your conversation. This site sees only the lookups your AI makes, stores nothing and needs no account. Worked out by this site
