HDoom is a testament to the versatility of the DOOM engine. By leveraging high-quality sprite work and complex animation cycles, it has carved out a unique—if controversial—niche in gaming history. Regardless of the subject matter, the project highlights how modular game design can be used to completely subvert a genre's intent, transforming a pioneer of the first-person shooter into a platform for detailed, character-driven animation.

| Item | Animation Type | Duration | |------|---------------|----------| | | "Healing" animation (third-person sprite swap) | 2 seconds | | Berserk Pack | Full-screen red flash + sprite transformation | 5 seconds | | Armor shards | Quick pickup – no special animation | 0.5 seconds | | Health bonus (pill bottle) | Consumption animation | 1 second | | Miscellaneous "prop" items (mattress, chair, chains) | Environment interactions (non-combat) | 3–10 seconds |

: The animations are notably smoother than the original 1993 game's frames, often featuring a higher frame-per-second (FPS) count to capture subtle movements.
