New character — Brawler: a tanky melee bruiser (+35% HP, +40% melee, knockback & regen; −25% projectile damage, −10% move speed)
New character — Gunner: a glass-cannon gunslinger (+25% damage, +20% fire rate, +1 pierce; −20% HP, takes +15% damage)
New character — Scavenger: an economy snowball (+50% coins, +25% XP, huge pickup range; −15% damage)
New character — Berserker: hits hardest near death (+15% crit, faster, ramping damage as HP drops; half HP, takes +25% damage)
New weapon — Giant Spatula: a slow melee sweep with huge reach and heavy knockback that flings the horde back
New unique upgrade — Soul Harvest: your ghost allies have a 25% chance to raise a new ghost from enemies they kill
New unique upgrade — Whispering Turret: your turrets have a 75% chance to raise a ghost from enemies they kill
New melee upgrade — Meat Tenderizer: +45% melee damage & knockback, but −8% crit chance
New melee upgrade — Butcher's Cleaver: +55% melee damage, but −15% overall damage
New melee upgrade — Cast-Iron Pan: +35% melee damage & big knockback, but −20% crit damage
New achievements — unlock each character: Knuckle Up (Brawler), Locked & Loaded (Gunner), Dumpster Diver (Scavenger), Off the Rails (Berserker), and Full Roster for the whole squad
New option — Damage Numbers frequency slider in the pause menu: show a number on every hit, every Nth hit (up to 1-in-20), or turn them off entirely
Soul Reaper — the ghost it raises now scales with the scythe's rarity: weak at Common, terrifying at Legendary (and the held scythe is bigger and easier to read)
Laser — now stuns enemies on hit, with stun length scaling by rarity
Smarter ghosts — a raised ghost now keeps the behaviour of whatever it came from: ranged enemies shoot, bombers kamikaze, chargers dash, watermelons slam — and their projectiles are now spectral black-and-white
Ghost ally damage rebalanced — ghosts now gain half of your ally-damage (Engineering) bonus
Melee reach — +Range upgrades now extend melee weapons too (at half rate), and the swing visibly reaches further from your body
Cold Snap — now slows enemies by 10% (was 3%)
Scrap Cannons — its +15% ally damage now costs −10% crit damage (was +10% enemy speed)
Achievements menu — cleaner, smaller, better-organised tiles
ater Tot now actually lands its melee hits — it closes the distance instead of hovering at gun range and whiffing
Melee weapons no longer miss at high attack speed (fast re-fires were cancelling the swing before it could connect)
Added a cap on simultaneous ghosts so the new ghost-chains can't cause slowdowns
The old Damage Numbers on/off toggle (replaced by the new frequency slider)
The "Getting Started" achievement category ("Finish your first run" moved into Survival)
Soul Harvest's chain doesn't trigger from Bomber or Watermelon ghost kills yet (their explosive kills don't carry the chain) — planned for a later patch
