Around 14 hours 34 minutes to beat, as shown, in this unedited playthrough. There was alot of frequent breaks and re-learning the controls and moves each time, so that made the playthrough more drawn out. I played this game very sporadically, with many months between many of the sessions. Thats one of the ways I complete a high volume of games, jumping around alot, but some games take a while to get back into the rotation.
Quite a good game overall. Feels like an action game from the Xbox 360 or PS2 era, which is good to see. The game has alot of abilities and moves, so taking breaks can make it confusing, as the game expects you to use most of them. My main issues with the game was getting stuck on objects when dodging, weapon switching not working most of the time (I think I needed to stand still, which is not a good thing to do in this game), and enemies that heal all their allies, tanky bosses and enemies that take too many hits.
There is ALOT of things to remember, so I would recommend playing this one consistently and not taking long breaks like I did. Its definitely harder to re-learn everything again when you are starting back at the hardest segments of the game, way beyond any tutorial phases.
