Dark Souls isn't my cup of tea. But I played Hollow Knight which is a 2D Dark Souls/Metroid game. I 100% it, but you can do more. The HARDEST boss ever. The final FINAL boss. A bullet hell combined with multiple other attacks at the same time. Then add platforming and a very specific upgrade build required to get the job done at a norm pace. Basically, imagine shooting a boss in destiny but you only had an auto rifle. You'd be there for 2 hours. I would need a walkthrough for Dark Souls.
