Your friends can join you to survive hordes of infernals in this free multiplayer. No server needed, just create the game and send the code to your friends.

Hellscape

Genre: 2D top-down co-op survival-run
Engine: Unity 6 (6000.2.0f1) · URP (2D) · New Input System
Netcode: Netcode for GameObjects (NGO) + Unity Transport + Unity Relay (DTLS native / WSS WebGL)
Platforms: PC · WebGL · iOS/Android
Modes: Single-player (local host) & 2–16 player drop-in co-op

Drop-in co-op. Kite huge enemy waves across a large arena. Over time, stronger elites appear—and so do weapon drops. Survive as long as you can, coordinate counters, and chase big scores.

Skills Showcase

• Hexagonal architecture (Ports & Adapters)
  Pure Domain (no UnityEngine refs) with App/Net/Platform/Presentation adapters. Clean boundaries, testability, and platform swap-ability.
• Deterministic server simulation
  Authoritative ServerSim ticks at a fixed step; domain-local Vector2, IRng (XorShift) and snapshot codec for reproducible replays.
• Authoritative multiplayer with Relay
  Host authoritative; clients send compact input via RPC; state replicated via NetworkVariables; Relay auto-selects DTLS/WSS.
• TDD-first workflow
  Domain features land with NUnit unit tests (EditMode). Unity CLI runner script for automation. 
• Modern Input
  New Input System with owner-only reads; mouse & touch-friendly aim abstraction; clean piping to authoritative sim.
• UI Toolkit
  Main Menu (Host/Join), In-Game HUD (team/personal score, health), hit vignette, pause/in-game menu.
• Content pipelines kept lightweight
  Stylized 2D sprites, 2D lights, “juice” via color flash / squash-stretch / particles. No skeletal rigs.
• Pragmatic networking glue
  Minimal RelayBootstrap for UGS setup, NetPlayer thin owner controller, SimGameServer bridge to the Domain.

Current status (vertical slice)

• ✅ Relay host/join (desktop & WebGL transport setup)
• ✅ Two+ players moving with owner-only input → server motion integration → replicated net positions
• ✅ Networked aiming &  shooting, hits register.
• ✅ Enemies spawn & chase players; constrained arena (walled rectangle)
• ✅ Players can die & revive (simple timer rule; host authoritative)
• ✅ UI Toolkit screens: Main Menu, In-Game HUD. In-Game Menu, damage vignette feedback and Defeat Screen are built but pending integration.
• 🚧 Weapon pickups & inventory (4 slots): base weapon (infinite) + three pickup slots (authoritative mergers/swap/drop) – rolling out now

Scope intentionally minimal per slice; features land behind tests and keep Domain pure.
