Ultimate Hit Reaction System is a powerful hit reaction framework designed for humanoid characters in Unreal Engine. It allows for rapid integration and brings high-quality, dynamic response animations to your game characters and NPCs. With a rich animation library and data-driven architecture, your combat feedback will become more vivid and responsive.

🔧 Key Features

• ⚡ Rapid Integration: Integrate within 30 minutes (basic knowledge of animation systems recommended). Setup is fully Blueprint + Chooser DataTable, no coding required.

• 🎥 Extensive Animation Library: Includes 168 motion-captured animations covering:

  • 🎯 Directions: Front / Back / Left / Right / Up / Down

  • 🔺 Strength Levels: Light / Medium / Heavy / Explosion

  • Includes partial hits, knockdowns, falls, launch reactions, combo impacts, and more.

• 🧠 Smart Animation Switching: Automatically selects appropriate animations based on hit direction and intensity—no manual setup needed.

• 🔁 Broad Compatibility: Built for humanoid characters and creatures. Compatible with diverse skeletal meshes and ideal for player characters, NPCs, and Bosses.

• 📊 Data-Driven Architecture: Behaviors are defined through Chooser Tables for easy tuning, expansion, and full multiplayer replication.

• 🧪 Physics Control(Experimental): Optional Physics Control module adds physical interaction to animations (experimental and toggleable).

• 🌀 Motion Warping Support: Fully supports UE’s Motion Warping system to dynamically adjust hit direction and landing position—making reactions like knockbacks and falls more fluid and accurate.

• 💀 Integrated Death Animations: Includes multiple death scenarios (e.g., instant collapse, knockback-to-death), seamlessly connected with the hit system for unified logic.

⚠️ This product includes the full animation set—no need to purchase additional animation packs separately.
