Soul merging – souls left on the ground now drift together and merge into one bigger soul you can grab in one go
Shop legendaries – Ezra's shop now always stocks at least one legendary card
Legendary cards – they now show up much more often: you're guaranteed at least one in every 3 card offers
Souls – brand new look: dropped souls now burn as a blue spirit flame that leaves a trail as it flies to you
Soul drops – enemies drop fewer but bigger souls, you still get the same amount
Performance – big explosions and Fanatic chain blasts are much lighter on your FPS
Gore – severed limbs, blood sprays and gibs are capped during big fights, and small gibs fade away after a while
Corpses – up to 18 bodies stay on the map at once (was 24), helping performance in late waves
Blood stains piling up for the whole run and slowing the game down in later waves
Big frame drops when several Fanatics exploded at the same time
Game size cut in half, from 2.8 GB to under 1.5 GB. Textures were trimmed to the detail you actually see in-game, so you shouldn't notice a difference.
Faster first launch: less to download before you can start playing.
Five Points runs a bit smoother in its busiest spots.
