This update fixes several bugs previously present on Brutal Doom v20, adds new stuff such as more death animations, even better gibs, a rebalanced and more satisfying melee system, and huge performance improvements.
The "Starter Pack Map Pack" comes separately with 32 new maps, featuring realistic environments, cities, outdoors, space stations, hellish cities, new enemies and bosses, all balanced for Brutal Doom's gameplay.
The entire campaign has a plot of how a demon invasion starts on a UAC Mars facility, then it breaks into Los Angeles, and UAC's Space Marines are deployed to save the city. All maps have continuous progression, every map starts where the previous map ended, giving a feeling of a big adventure instead of just random maps placed in a megawad. Maps that takes place on Earth even have daytime progression (first map starts at dawn, second map at noon, third and fourth maps in different parts of dusk, next map is at night, and so on).
Brutal Doom v20b and the Starter Pack maps are coming on December 31.
On this other video, you can notice how much the performance on v20b was improved. Maps previously unplayable on v20 now works like a charm.
