TL:DR, the Tide trilogy is a better successor to L4D than Back 4 Blood is.
It kinda makes me think of how Turtle Rock really doesnt know what theyre doing
L4D was carried by Valve, and thats especially obvious when you see how B4B was intended to be a spiritual successor to L4D but fell flat in almost every department.
Then you have the Tide trilogy by Fatshark,
They nailed the gameplay that L4D's genre of horde shooter provides.
In b4b, special enemies can have several different variants with their own little quirks.
I think Tall Boys have 4 variants?
Meanwhile Darktide has at most, 2 variants of a special enemy, but even then theyre very distinct from each other. Both visually and mechanically.
Scab Gunners are wearing armor and use laser weaponry, whereas Dreg Gunners do not wear armor and use ballistic weaponry.
Scab Flamers are distinct from Pox Flamers
The 4 Boss types, Plague Ogryn, Beast of Nurgle, Chaos Spawn, and the Daemonhost, feel unique from each other. The DH being most akin to the L4D witch but much tankier and can (and if unprepared or dont have a certain build WILL) kill a party member. (Recently nerfed, used to kill party members scaling with difficulty, now caps at 1 party member even if on Difficulty 5)
You know when an elite enemy spawns in, due to the simple fact of..
They never shut the fuck up.
They CONSTANTLY talk.
Snipers dont talk, but they have a big obvious laser sight and when they're about to shoot, make a big obvious audio cue.
Part of what makes a Horde Shooter is the sound design, and if youre in the middle of a horde, shooting or cleaving you way through. It would feel bullshit if suddenly you were pinned by a disabler enemy that you didnt know was there. But even then, theres only 2, 3 at most, enemies that actually pin you. Those being Trappers and Pox Hounds (and the weaker pox hound variant when part of a mission modifier)
Every other special just keeps you pinned in other ways, for example:
Area denial via flame and pox bombers
Area denial via Scab and Pox Flamers
Pinning your movement down by filling the air with an unholy, heretical amount of bullets and lasfire.
Snipers.
All in all, the enemy and sound design alone elevate Darktide above B4B.
Then theres the actual mechanics of gameplay
Darktide and B4B both have wound systems
But Darktide handles it MUCH better, allowing multiple opportunities to heal, and, if you have certain build, you will regenerate wounds. You dont have to worry about weapon rarity mid-match, instead picking your loadout before the game starts and loading in with a Gun and Melee of your choice.
And with the recent Unlocked and Loaded update, its even easier to get the perfect weapons.
Ammo is usually plentiful, and if you are playing a Psyker (the magic class) more often than not youre not using ammo at all, instead using a staff which uses your Peril, a currency that, if overloaded, causes you to down. Its a form of overheating.
Ive rambled on enough, but thank you for taking time to read my rambling about a game i enjoy
