I don't think it's just their twitter, the whole game really struggles from the tonal shift between the solemn "here are facts about the war that we're trying to honour" and "here's goofy videogame bullshit".
Sure, but I kinda get that, at the end of the day they're making a videogame that's supposed to be fun to play so that tonal disconnect is somewhat expected.
However, the shitty memes from that twitter account are totally out of place and just plain bad.
