I’m not completely clear on the situation: is this a video game, where a character uses that expression? Or an online or face to face game where a fellow player used the phrase?
Either way, I think you’ll feel better if you make an effort to let the responsible party know you find the remark distasteful.
But when you look at the actual words, they aren’t particularly offensive: they don’t indicate that Jesus wasn’t resurected, or take his name in vain. It almost appears the words were chosen to step right up to the line of swearing without quite crossing it.
Give the casual profanity that permeates the culture, I think I’d be willing to let this slide if the game experience were otherwise positive.
