Modular enemy AI for Unity 6 with stealth perception, memory, explainable decisions, coordinated search, predictive pursuit, formations, real cover, and fire-and-maneuver.Requirements and dependenciesRequires Unity 6.1 (6000.1) or newer and a Universal Render Pipeline (URP) project. Verified on Unity 6000.1.2f1 and 6000.4.5f1.Required Unity Registry packages:• AI Navigation (com.unity.ai.navigation), version 2.0.12 — navigation and NavMesh baking.• Input System (com.unity.inputsystem), version 1.19.0 — playable examples and preview controls.• Universal RP (com.unity.render-pipelines.universal) — use the version supported by your Unity editor: 17.1 for Unity 6000.1 or 17.4 for Unity 6000.4.These packages are available through Unity Package Manager. Install them if they are not already present. For the examples, set Player Settings > Active Input Handling to “Input System Package (New)” or “Both”.The included materials and example scenes support URP. Built-in, HDRP and custom render pipelines are not supported package configurations in this release.No additional paid Asset Store asset, external AI service, API key or subscription is required. Argus Core functionality is included; do not install the standalone Core package alongside Pro.Custom characters and integrationsAn included starter character and four Humanoid animation sets let you begin without purchasing character content. Custom Humanoid models require a valid Unity Avatar. Generic models require animations made for their skeleton. Argus does not automatically rig arbitrary meshes or generate missing animations. Custom movement, combat and health systems can be connected through the documented interfaces and may require adapter code.Optional: Unity Test Framework (com.unity.test-framework), version 1.6.0, is required only to run the included tests.What is Argus Pro?Build enemies that act on evidence—not hidden player state.Argus Pro is a modular enemy-intelligence runtime for Unity 6. Add the Argus Pro Enemy (Drop-In) component to assemble perception, suspicion, NavMesh locomotion, memory, decision-making, squad tactics, cover combat, health, aiming, and weapons—or integrate individual modules through public C# interfaces.Enemies can:See, hear, smell, discover clues, react to lighting and crouching, and escalate through five suspicion levels.Remember observations after contact is lost and exchange imperfect, timestamped reports with nearby allies.Divide investigation and search work instead of repeatedly checking the same locations.Predict escape trajectories from genuine observations without reading the hidden player Transform.Assign pursuers, interceptors, containment roles, pincer wings, support, and reserve positions.Discover or use authored cover, claim separate positions, peek for bounded firing windows, recover, and reposition.Suppress targets, protect one advancing teammate, hand off covering fire, and retreat when badly wounded.Explain their decisions through readable scoring evidence, reasoning traces, contracts, and debugging tools.Choose from Balanced, Aggressive, and Defensive archetypes, or tune every system independently. The included NavMesh implementation can be replaced with custom locomotion, root motion, KCC, A*, ECS, or another controller through a public interface.Argus Pro includes the complete Argus Core feature set. Core provides perception, awareness, suspicion, basic guard behavior, and alert propagation. Pro adds durable memory, imperfect intelligence sharing, utility decisions, coordinated investigation and search, tactical actions, predictive interception, combat formations, cover combat, fire-team coordination, advanced tuning, and reasoning tools. Install Core or Pro—never both.Includes full commented C# source, comprehensive documentation, a playable stealth demo, nine focused micro-demos, and a fifteen-scenario Argus Pro Feature Lab.Argus Pro provides enemy cognition, tactical decisions, and a reference combat stack. Bring your own production character art and animations. It uses deterministic gameplay AI—not machine learning, generative AI, cloud services, or subscriptions.Third-party licencesArgus Pro includes assets from Quaternius’ Ultimate Animated Character Pack, Animated Guns Pack, Modular Dungeons Pack, Ultimate Modular Characters and Universal Animation Library, and Kay Lousberg’s KayKit Character Animations, under CC0 1.0 Universal (Public Domain Dedication).
