Honestly one of the best games in the Doom franchise. The level design is great and the enemies are the same as Doom 2, except for a new type of imp and the final boss. The arch-viles and chaingunners from Doom 2 are thankfully absent from this game as well. I especially like the secrets in this game, shooting switches and figuring out how to get the demon artifacts was fun. All the weapons are the same as the Doom 2 ones except for the Unmaker which is a cool addition if you can get the demon artifacts to power it up, without those upgrades it kind of sucks though. The music focuses much more on the horror atmosphere, so there aren't any metal tracks sadly, but the music does do a good job at creating a spooky ambience to everything. It's really evident how much more advanced the scripting is in this game's levels compared to the first 2 Doom games, which makes for some really cool moments. Enemies also usually spawn in instead of already being placed in the map, which makes the game feel a lot more tense as you can't be sure if any enemies will spawn in areas you have already been in. I really liked playing this game on the highest difficulty, it made for a good challenge but wasn't too difficult overall, it was especially great when playing through the lost levels, which you unlock after beating the main game. It was also pretty fun to go for all the achievements, they added a little bit more to the game in my opinion. Overall, this game definitely stacks up to the Doom franchise's other games and makes for a really solid entry.
