Both singleplayer. Quake has an amazing singleplayer mod scene right now, thanks in large part to Arcane Dimensions and I had two separate attempts to beat the Unreal campaign recently lol (I don’t know why but the last 1/3 of the game always causes me to turn it off and never come back, even dating back to 1999 or so when I first played it lol) Finally beat it this year.
