What is 4x402?

4x402 is an async multiplayer strategy game built for the Farcaster community. Four players compete to dominate a network of interconnected nodes, expanding territory, managing resources, and outmaneuvering opponents over the course of several days.

4X Strategy

Explore unknown sectors. Expand your territory. Exploit resources. Exterminate opponents.

Status 402

Built on x402 protocol. Real micropayments power mercenaries and intel.

Think Neptune's Pride meets Bloomberg Terminal. A dark, data-dense interface where nodes pulse with activity, and every decision matters. Games are slow and strategic—check in a few times a day to issue orders.

Core Concepts

The Map & Fog of War

The game takes place on a network graph. Neutral nodes fill the center, and uncharted territory surrounds you. You can only see nodes you have scouted. Unexplored nodes appear as dim, unknown markers—their value and potential danger hidden until revealed.

The Tick System

Time advances in 30-minute ticks. You can issue orders at any time, but they resolve when the tick processes.

Tick Sequence
  1. Resource Generation (Credits)
  2. Military Regeneration
  3. Action Resolution (Combat, Movement)
  4. Loyalty Updates
  5. Win Condition Check

Intel Marketplace

Information is power. The marketplace allows players to trade scouting data for real money. Sellers receive 80% of the sale price.

Buying & Selling

Selling

After scouting a node, you can list it for sale ($0.10 - $0.25). It remains listed until sold or expired.

Buying

Browse listings manually or set Standing Orders (e.g., "Auto-buy intel within 3 hops").

Strategic Value

  • Early Game: Profitable for active scouts mapping the board.
  • Mid Game: Information dries up as borders harden.
  • Late Game: Espionage. Is that listing real, or a trap? (Note: Server validates stats, so sellers can't lie, only selectively reveal).

Win Conditions

  • Domination

    Control 60% of all nodes.

  • Elimination

    Be the last player with a Nexus.

  • Economic

    Maintain 500k cr/hr income for 24 hours.

Social Layer

4x402 is built for Farcaster. The social layer isn't in the game—it is the game.

Diplomacy

There are no in-game alliance mechanics. All deals happen via DMs or public Casts. Betrayal is possible, but your reputation persists across games.

Casting

Notable events are cast-worthy. "Just captured @dwr's Gateway." or "$5 USDC bounty on @rival". The drama generates content.

Reputation

Your history is public: Win/loss record, betrayal count, and abandonment rate. Frequent backstabbers will find it harder to make deals in future games.
