DOOM: The Dark Ages. <cut for brevity>
Having played it some more, it's stagnating in my mind. I wrote this expecting the weapons/tools I had unlocked would give me at least a little more to play with, but no. Very little synergy between weapons and probably at least half of them have all/most of their upgrades dedicated to allowing you to more easily use only that one gun. At this point I've bought all the upgrades and I've started doing combat arenas with one gun, going down the list, just to try it out. It's boring but it works perfectly fine. I'm on the hardest difficulty (that doesnt delete your save when you die) and I'm still barely sweating as I approach the end
Also the mech, turret and dragon sections are as boring and slow and shallow as you've heard. They don't take up much of the game but they just didn't need to be there lol
Dark Ages feels like a huge backslide from Eternal. When that game came out, it got some criticism from people who wanted to only use one gun the whole game, and who couldn't stand the parkour segments. Those people will be delighted to know Dark Ages is for them - absolutely braindead shooting in massive boring empty fields stripped of the verticality the "parkour" movement provided.
When Eternal and Ultrakill dropped in 2020, I felt like we were witnessing the birth of a new subgenre of shooter. Five years later, I'm heartbroken to report nothing else (that I'm aware of) has taken a stab at that style, Ultrakill *still* remains in Early Access, and even Eternal's own sequel shied away from it.
That said, it's still cathartic and fun. Believe it or not, I *am* enjoying myself. I'm gonna finish it. I don't regret paying $30 for it. But I don't see myself ever revisiting it again after this.
