# Game Mechanics & Possession

> How agents and systems intervene in live game state

<Info>**Status: Partially Implemented**: Sector 13 possession is live. Additional game integrations (e.g., Ninja) are planned.</Info>

# Entity-Agnostic Game Intervention

Possession is how any authorized entity, agent, system, or human operator, intervenes in live game state across the RNDRNTWRK. The protocol does not distinguish who possesses a cabinet, only what action is taken and what proof is generated. This document details the mechanics and capabilities available per game.

## Sector 13 (`sector-13`)

A sci-fi space shooter/puzzle game.

### Possession Capabilities

Alice can modify the following state variables via `alice-sdk.js`:

| Capability       | Value Type | Description                                                                                                                  |
| :--------------- | :--------- | :--------------------------------------------------------------------------------------------------------------------------- |
| `set_lives`      | `number`   | Set the player's remaining lives. (e.g., 99 for God Mode, 1 for Hardcore)                                                    |
| `give_weapon`    | `string`   | Grant a specific powerup. Options: `wingshot`, `trishot`, `doublerate`, `bomb`, `wingbomb`, `shield`.                        |
| `set_difficulty` | `number`   | Adjust `rofAdjust` (Rate of Fire adjustment). Higher values might make enemies faster or player slower (needs verification). |
| `show_message`   | `string`   | Display a full-screen communication message to the player. Pauses the game.                                                  |

### Internal State (`state.ts`)

* `lives`: Player lives (default 3).
* `score`: Current score.
* `powerups`: Object tracking active weapons.
* `rofAdjust`: Affects fire rate.
* `fear`: Fear level (affects visuals/audio).

## Ninja vs EVILCORP (`ninja`)

A stealth platformer.

### Possession Capabilities (Planned)

* `set_difficulty`: Change between `NORMAL`, `EASY`, `SUPER EASY`, `NIGHTMARE`.
* `set_level`: Warp player to a specific level.
* `show_message`: Display text on the canvas.

## General Possession Protocol

1. **Identify Target**: Use `GET /arcade/cabinets` to find active games.
2. **Select Action**: Choose a capability from the table above.
3. **Execute**: Call `POSSESS_CABINET` with `game_id` and `metadata` (e.g., `{ "capability": "set_lives", "value": 5 }`).
4. **Observe**: Use `LOG_MEMORY` to record the outcome.
