These were definitely more over the top, more so than most mainstream horror games. But I don’t think anyone’s saying they were inherently sexualized.
Although there was that one quote from the game’s executive producer that should stick out like a sore thumb…
The reason the death scenes are censored like this is because game journalists saw the gruesome death scenes in the first Tomb Raider remake and said, "Yeah these are inherently sexualized deaths."
TL;DR - Some game journos have a weird gore fetish, got uncomfortable, so now we can't have violent deaths in Tomb Raider anymore.
