Can't remember the state of the DLCs, I think you all need to own it but I wouldn't swear to it, I feel like it may have changed to needing it. Double check!
DLC includes more missions, different game modes, more weapons, new character classes and lastly, skins.
Not fighting zombies, you're fighting ratties from warhammer! And chaos! And beastmen (if you have the DLC)!
It's a melee focused PvE game (now also has PvP). There are ranged weapons, but ammo is less available unless you play a more ranged class - or wizard. Also a grenades, health items, and buff potions are items you can find during a mission.
5 different characters with their own flavour and they do have banter during the matches. Each character has by default 3 different classes (an extra with each character DLC).
Different classes do play differently, as well as different characters.
Multiple missions available.
Different types of each race of enemies.
So you'll get basic rats with just a weapon, some with weapon and shield, some in armour, some in armour
and a shield, some crazy ones that will proceed to try and do a flurry of slashes at you.
Chaos you'll get similar, basic with a weapon, then some with shields, then an executioner style with a big axe, a chaos warrior in heavy armour, and a berserker wielding dual axes that will run and jump at you.
Beastmen - honestly can't remember much. Archers, guys with melee weapons and banner carriers that'll put down a banner and buff all the others.
You'll get 'monsters' - big baddies that are kinda like a tank, but there's a few different types that fight differently and they're bigger in size vs a tank
You'll get bosses in some missions, each with different attacks IIRC.
There are also "special" enemies, these include (again names are probably wrong)
- Assassin - it's a hunter, but it can't bounce and it can go invisible
- packmaster - it has a big grabby stick, he'll come and grab you, drag you off and you can do nothing. Other enemies will attack you. He'll then hoist you up
- Warpfire thrower - it's a flamer rat
- Rattling gunner - it's a rat with a big minigun
- Globardier - throws globes into the air to come back down and smash around you putting out poison gas
- Blightstormer - creates a damaging tornado that will hurt as well as picking you up and throwing you somewhere. They're not always immediately visible as they can do so from afar
- Leech - will teleport in and "Shang Tsung" you. Picking you up and leeching your soul from you
There are multiple weapons that can be unlocked, one handed swords, sword and shield, two handed sword, flail, mace, halbard, spear, spear and shield, axes. There's a fair few.
There's weapon crafting and tiers of weapons
There are also stats for your weapons i.e. increased crit chance, increased crit damage, x% increase to *enemy type*
Later tiers of items add effects (which i can't think of any off the top of my head)
Also some other equipable items for more stats.
Your character also has levels - which will increase your damage. No prestiging though.
You will need to level each character seperately, and their weapons are not shared. Their other equipable items are though IIRC.
Melee attacks will require you to aim a bit - it's not skyrim swing and hope for the best. That said, I'm not great at the game and get by - it's not Chivalry for example. But each weapon can feel different and enemy armour does mean you might need to think a bit about how to fight something - heavy attack, different attack, shield bash etc
Ranged has multiple weapons too, guns, crossbow, normal bow, flamethrower, fire pistols. Some are unique to classes not just characters, though i think this applies to melee weapons too.
The wizard - the wizard is a bit different, and works like the flamethrower and fire pistols. They have no ammo, but have a heat bar. Fill it up and you blow up going down.
Each class has a different special ability, and skill tree (though there's some overlap between classes and characters)
Your main ability is on a cooldown after use and then can be reused.
Chaos Wastes - my preferred game mode! Was a free adition to the game, and has a random element to the game. The maps are semi random and you progress through a run picking a path, each map may have a "unique" twist to it, shown on the map. Weapons start of as rubbish tier, and you collect coins during each map. Coins can then be spent on upgrading a weapon to a specific tier, swaping your weapons for a random of a specific tier, getting a new random skill (might be awful) and buying items on the shop spots on the map. There are also challenge chests that award you with a choice of perk for free.
There's another game mode called weaves (i think). It's not free, it's part of a DLC. I'm not sure anyone plays it much, it was a semi random map so a bit like a precursor to chaos wastes but there is some progression. Not really done much on it.
There's also a horde mode map - I don't play that tbh.
There's also PvP, which I've not tried.
I think I've got everything.
