As groundbreaking a game DOOM was, I think it’s fair to say that DOOM 2 wasn’t a huge step forward. It’s basically an expansion pack but well it was the ’90s and we didn’t mind that so much.
And that double-barrelled shotgun was seriously awesome! Chick-chick-BOOM.
The game itself was great, but what made DOOM 2 legendary for me and many other people were the mods people made for it. I was a big fan of the Aliens one, of course, but always had a soft spot for the Simpsons mod where we went around eating donuts.
