Build with AI

Want to prototype a native Unreal game faster? Seele Agent from SeeleAI turns a natural-language idea into an editable Unreal Engine 5 project in the browser.

• 🧠 Describe a genre, scene, mechanic, or visual direction in plain language, then use an AI-generated starter prompt to shape the project.
• 🏗️ Generate a native .uproject with project files, gameplay, camera, controls, environment, and visual direction instead of a non-Unreal mockup.
• 🔍 Review the running game in the browser through Pixel Streaming, iterate on the prompt, and inspect the result before moving deeper into development.
• 🚀 Continue in Unreal Editor for Blueprint, C++, asset, platform, and engine-level customization, then package, download, or publish the result.

Try SeeleAI Unreal Game Creator when you want to move from an idea to a playable Unreal prototype quickly.

Featured games & projects

★ Star counts checked on 2026-08-29; they may change over time.

🏕️ Survival & horror

• EpicSurvivalGame · ★ 3,397 · MIT · UE4

  A third-person survival sample project organized around common survival-game building blocks. Study its inventory, interaction, item-use, and gameplay-loop structure when you want a concrete playable reference.

• UnrealApocalypse · ★ 0 · MIT · Not stated

  An open-source Unreal survival-horror game project with a focused gameplay premise. It is useful for examining how atmosphere, combat, level design, and horror interactions are assembled into a contained project.

⚔️ Action, RPG & fighting

• ActionRoguelike · ★ 4,569 · Unreal Engine EULA (game assets) · UE4/UE5

  A C++ action roguelike project demonstrating combat, abilities, AI, items, and multiplayer-oriented patterns. It is a strong code-first reference for organizing a compact but complete gameplay prototype.

• ActionRPGGame · ★ 1,038 · No license file found · UE4

  A UE4 action RPG starter project for examining foundational RPG systems such as character control, combat, abilities, and the structure of a small gameplay codebase.

• NightSkyEngine · ★ 323 · MIT · Not stated

  A C++ fighting-game framework for prototyping combat, character controllers, and other close-range gameplay systems. Open it when you want to study a framework-oriented approach rather than a single finished game.

🎯 FPS

• SimpleFPSTemplate · ★ 681 · Unreal Engine EULA · UE4

  A compact C++ FPS template with the basic shape of a playable shooter project. It is a practical starting point for learning player input, weapons, targets, maps, and Unreal project organization.

• Project-Isolation · ★ 14 · MIT · Not stated

  An open-source C++ first-person shooter project that is useful for reviewing how a complete FPS codebase handles its gameplay loop, player-facing systems, and project-level organization.

🕺 Animation & gameplay systems

• GASPALS · ★ 1,172 · UE-Only Content License · UE5

  A UE5 animation sample that combines the Gameplay Ability System with ALS layering. Use it to study locomotion, animation layers, and reusable character-system integration.

• FlowGraph · ★ 1,895 · MIT · UE5

  A node-based flow system for building dialogue, branching stories, and other narrative logic. It is a useful example when your project needs visual authoring for sequences and interconnected gameplay events.

• MassSample · ★ 1,117 · MIT · UE5

  A community sample for Unreal's experimental Mass Entity framework. Use it to study data-oriented entity processing and compare Mass-based gameplay architecture with actor-centric projects.

🏙️ Simulation & building

• LifePlay · ★ 29 · MIT · UE4

  A UE4 life-simulation game project for inspecting a larger simulation-oriented codebase and the systems needed to represent persistent activities, characters, and an open-ended gameplay loop.

• city-form · ★ 1 · MIT · Not stated

  An open-source city-building game for exploring simulation, construction, spatial organization, and world-management systems in an Unreal project.

🧱 Gameplay architecture samples

• GASShooter · ★ 1,164 · MIT · UE4

  An advanced FPS/TPS sample built around Unreal's Gameplay Ability System. It demonstrates how abilities, attributes, effects, weapons, and networked shooter gameplay can be composed in a larger example.

• Bomber · ★ 379 · MIT · UE5

  A small Unreal project designed as a clean learning codebase, combining modern UE5 features with multiplayer functionality. It is useful for readers who want a compact project to inspect before tackling larger samples.

🚪 Focused indie projects

• Budget-Backrooms · ★ 31 · GPL-3.0 · UE4

  A focused UE4 single-player Backrooms game with a contained scope. It is a convenient reference for studying an atmosphere-led indie project, compact level design, and a clearly defined player experience.
