Finished translating the rest, this is what was missing for people who read it before the edit:
In the article itself, the workers interviewed by Vandal are wary of the figure, and all the employees interviewed by AnaitGames agree. "I was never told of any conditions to be credited. I thought it was a given". I was surprised to read that percentage in Vandal". argues a former programmer. "At no point did they tell me how long I'd have to work or what the minimum time was to be credited. I was surprised to read it in Vandal because it wasn't written anywhere. I had assumed I would automatically be credited since I worked on the game, especially because I saw parts of my work were kept untouched in the final build. It's clear nobody modified that part of my work", points a former employee whose contributions to the game's art direction are evident even from the trailers.
For one of the interviewed artists, behind the decision of whether to credit some employees or not hides a "punishment culture", and other workers agree: "I believe it's a punishment not to credit those of us who contributed and had to leave the studio because our work is there. It's in plain sight. To me that's punishment culture. There is, and up to a point it's justified, a huge sense of pride and arrogance that ends up backfiring. It's obvious they've just made the best game ever to be created in Spain and now their ego is enormous, but I don't know why they punish those of us who did our small part, rather than sharing the accomplishment. It really sucks to see things I've worked on and it's not acknowleged.
A colleague describes his disappointment after discovering on release day that his months of contributions were not properly credited. "I believe my work has been relevant and it was enough to be credited. I get that I don't own the rights to my work because my contract says so, but I should still be credited because my work is in the game as I created it. Due to IP laws and NDAs I can't use my work as a letter of application to other companies, so the only way to prove is through the game's credits". He points out that the situation is not just damaging in regards to job prospects, it's also emotionally draining: "Being in the credits is exciting to us and it makes us proud. So when the day comes and you eagerly look it up, only to not find it, it's a big blow. It's been a few emotionally trying days for me since the release. Not just emotionally, since it in a way it makes you feel excluded from the project, but professionally as well (...) I just wanted to enjoy revealing that I worked on the game, as others have, that's something that's been denied to me and it makes me sad. It was something I needed".
Moreover, even though in the "team Metroid" picture (published through private groups) over 50 people are missing, these former employees argue that there's a general sense of fear of speaking publicly about the conditions within MercurySteam. "I think they're taking advantage of the fact that people are afraid to speak publicly. I know two other people who weren't properly credited but I understand they're afraid of speaking out because it feels like your career is over". A colleague blames the leadership as the source of this fear: "The main leaders know a lot of people and they can screw your career if they have a problem with you. They don't care about badmouthing you and destroy your career, so people don't talk". he says.
But even beyond company leadership, it's relatively easy to find accounts which praise the huge talent in the middle and lower job positions and the internal fellowship within the teams: "The relationship between colleagues and the day to day for the "foot soldiers" was amazing. I had a great time, I've never laughed more at any other studio. And even though there was a sense of competition, that's normal in creative jobs because we all want to be the best". They also have very kind words for Metroid Dread: "It pains me not to be in the credits because it makes me so proud. This game is already part of the history of game development in our country".
Really a sad, annoying situation all around. These peeps deserve management worthy of their enormous talent.
