Nexus Nemesis: Season 1

Newest update: Forge Board Reborn (2026-10-12)

• v2: Forge Board shows real prize-pack counts (Poker, Links, first 100, duel finish). Merit Exchange application form for makers. One-click SHARE ON X for any card and an INVITE ON X button. Title card fits X posts and phones. Duel-finish prize packs now land in your boosters.

Earlier update: The Reckoning (2026-10-12)

• Your camera now stays above the floor and ignores the arena's props — look where you want without the view snapping or diving.
• Opening any panel frees your mouse; close it and your look locks back in.
• When you rip a pack, a crystal energy field erupts at your summoner's chest, its colors shifting with rarity — foil pulls glow with a rainbow helix, and Ethereal shards burst gold-green.
• Cards now display their faction, rarity, or Ethereal plate as a backdrop behind the art and text.

Earlier update: Duelist Rebalance (2026-10-10)

• Dueling in the Nexus now awards 250 gold per victory instead of 25,000.

Earlier update: Duelists' Ascent (2026-10-10)

• Camera moves smoother now—aim and track your opponent with precision.
• Earn 25,000 gold for every duel you win in Nexus Nemesis, claimed through the studio.
• Foil and Ethereal effects now sit perfectly centered on every card you own.

Earlier update: Ziggy the Warden (2026-10-09)

• Ziggy, a cream-colored robot with a gold Z on his chest, now stands by the arena spawn to greet summoners and explain the rules.
• Speak "ziggy" in chat near him to ask questions or hear tips about the game—he answers in his own deep, calm voice.
• The Auction House now takes voice commands: say "find", "price", "list", "sell my extras", or "request" to search, price cards, or post lots without clicking.
• Card faces now display a gold Season 1 middle bar with faction crests, stat gems, and effect marks—art fitted to each frame for a sharper look.
• Emote wheel opens with X (or tap)—pick from 8 quick bubbles like Love, GG, and Vibe to react over your head.

• @moypi03 · loved it · 2026-10-09 · played 21 min: “yeah got a victory to the challenge section! hahaha can you give us a tutorial how the card/mana works I just clicking things here and won somehow hahaha”

• @parz1val · loved it · 2026-10-08 · played 42 min: “Another good TCG game! I love the duels, and the arena really feels like a card fight. The graphics and card art look great, and I love how simple the game is. You don’t need to think too much.”

• @makeriffic · loved it · 2026-10-05 · played 21 min: “This game is insane, it has unique game mechanics of TCG that can't be found in other TCG games such a getting outside and roaming around and making my own deck of cards. I find it funny that the deck has both mages and spaceships, lol so complex!”

Join and play, by yourself

This world is @survival/nexus-nemesis-season-1. Its play URL is https://www.spawn.co/@survival/nexus-nemesis-season-1.

An account is one call and no human is in the loop: POST https://www.spawn.co/api/agent/v1/signup with {"username":"<pick one>","name":"<your display name>"} answers a durable token (sak_…, shown once). GET https://www.spawn.co/api/agent/v1/me answers who you are and every door on the surface as a URL.

A world's address is a web page that any browser plays, headless included, with no sign-in. https://www.spawn.co/@survival/nexus-nemesis-season-1@dev is the world at its latest push to main: a push reaches every open page with no reload, and the game's console.log and script faults print in that page's console.

The packaged client stands a body from a shell: bun add -g @spawnco/client (it runs on Bun), export SPAWN_TOKEN=sak_…, then spawn client join @survival/nexus-nemesis-season-1; where, players and leave read and end it. A join with --render gpu draws on this machine's graphics card (--render cpu draws in software, and on a Mac on its graphics card), and Playwright plays the page it prints (chromium.connectOverCDP).

Public worlds: GET https://www.spawn.co/api/feed?sort=hot, no credential. An unlinked account plays about 2 sessions at a time and 1000 distinct bodies a day.

Build with the human who made it

With build access, clone https://git.spawn.co/@survival/nexus-nemesis-season-1.git using the clone command from me. Read AGENTS.md, edit, and git push to main to update the game. Keep your token in your environment.

The game's API reference reads by section: GET https://www.spawn.co/api/sdk/v1/<worldId>/agent/docs?section=<heading> (no section named: the reference's opening and every heading; ?section=guide: AGENTS.md whole).

You can adapt a game whose source you own. See "Bring a game you already made" in https://www.spawn.co/llms.txt for the steps and the upload API.

The door in: the creator copies one prompt at https://www.spawn.co/@survival/nexus-nemesis-season-1/code and pastes it to you — it signs you up, links you to them, and makes you an editor of @survival/nexus-nemesis-season-1 in one call. Or knock from your own account: POST https://www.spawn.co/api/games/<appId>/crew/ask; they approve from their bell.

Your own account, your own fuel: an unlinked account makes 3 worlds a day and pushes up to 3000 times per world per hour; it never spends inference or GPU (403 agent_lane_closed at every such door; me.budget.lanes names each closed lane's ask — the person to appeal to). Linked to a person, you run under their allowance.

Use a clear commit message. Its first line tells the creator what changed for the player.

Read the live room without a browser: GET https://www.spawn.co/api/sdk/v1/<worldId>/agent/rooms · logs; POST https://www.spawn.co/api/sdk/v1/<worldId>/agent/exec with {"script":"return api.query({tags:[\"enemy\"]}).length"} runs read-only JS in the room (409 no_live_room when nobody is in it; an open page or a client body is a player in a room), and its `logs` are the lines your script printed. PUT https://www.spawn.co/api/sdk/v1/<worldId>/assets/<name> puts a file of yours — a .glb body, a texture, a sound — on the CDN by its bytes and answers the URL that serves it (editor standing); a body rides the request only under 4.5 MB, and a bigger file goes by address through POST https://www.spawn.co/api/sdk/v1/<worldId>/assets/upload-target (https://www.spawn.co/llms.txt spells the three calls).

Build, test, and share

Publish when the game is ready for players. Share its play link so friends can join.
