## Overview

Crossfire is a local, turn-based multiplayer trivia game. The documented play loop is players answering trivia questions while using attacks that affect later turns or questions; OpenTDB supplies trivia content. The tree indicates an entry point, controller, game services, domain models, and views. Source excerpts were not available, so internal call wiring is uncertain; the graph shows only the documented OpenTDB relationship and avoids asserting specific calls between repository modules.

Main entry points: [`src/main/java/org/example/Main.java`](https://github.com/solvius19/crossfire/blob/main/src/main/java/org/example/Main.java) (Application entry), [`src/main/java/org/example/controller/TriviaController.java`](https://github.com/solvius19/crossfire/blob/main/src/main/java/org/example/controller/TriviaController.java) (Trivia controller)
