Just 100%ed Death's Door the other day, no Google help. Found the real ending and secret end boss. All secrets, powerups, weapons and collectibles. Game file says 100%
20 hours it took.
I would need to play through the game again with just umbrella as weapon to get the last 100 achievement points. Oh and I missed my chance to get the lil creatures who follow you around and infest the commission headquarters, to follow me through the metal detector there. So I'd need a new file to get that too. So almost got 900/1000 achievement points.
One of my favourite games of all time. 9.5/10 I'd give it. Honestly. The atmosphere, music, the lore, the graphics, the secrets, the boss battles.
Anyone else who got the real ending notice the inspiration they took from full metal alchemist? The eye of truth. The soul bonding to a piece of armour? Nice!
