Doom 2 is basically just more Doom but I found most of the levels to be more tedious and annoying.
The game still plays really well and the weapons are all very satisfying and meaningfully different, so it is still a blast to play.

In general more levels rely on surprise monster closets or teleporting hordes for difficulty. They also just employ throwing a ton of very hard enemies at you at once, which feels grindy and cheap in this game.

Maybe worth playing through. I will probably never touch it again since Doom 1 gives you the same gameplay, just better.
