Out of boredom, I went to the store page of a certain recently released half life fan mod on steam to read the negative reviews, and noticed something weird on the "is this game relevant to you?" bit
A single player game with a plot more laughable then bad DA fan fic is apparently, somehow similar to Left 4 dead 2.
Maybe Steam considers them similar because of all of the blatant L4D assets the game steals.
I'm so sorry for reminding people that this terrible half life mod exists, I just found this kind of amusing, but this post is probably lower quality then the average shitpost.
