Quake: Dawn of the Machine - MachineGames
I’ve gotten back to Dawn of the Machine after getting stuck, and then deciding to play through every other official Quake 1 level set. This one was released recently by MachineGames for the 30th anniversary of the original game, and it’s very hard. You start the game with a reduced maximum health and ammunition for each of the weapons. There are pickups throughout the levels that will bump these up a little bit. Several of them are well hidden, I doubt I got half of them to be honest. Several of the levels took me around half an hour to beat, and had over 200 enemies in them. They will regularly spawn the hardest enemies in the game one after the other, often in places where it is extremely hard to dodge their attacks.
