I’m trying to find a mobile game from around 2017–2018 that had gameplay very similar to Dynasty Warriors: Unleashed. It was a 3D action hack-and-slash game with large-scale battlefield combat where you fight waves of enemies in real time, very Musou-like. The camera was angled/top-down during fights and it used a mobile ARPG layout with skill buttons on the right side. You could switch between multiple characters during combat, and progression was done through a stage-based map system with selectable missions shown as nodes or flags. Before entering battles, there was a cinematic transition into the battlefield that looked like a horse-riding or mounted-style entry cutscene. The visuals were more realistic or anime-real rather than fully cartoonish, and the overall combat feel, animations, and pacing were extremely close to DWU.
There was also a companion/character recruitment system that felt like gacha, where you could obtain or “search” for companions, and there was a chance system involved—some outcomes could result in losing or failing to obtain characters, making it feel higher risk compared to typical gacha systems.
