Billion Nemesis is a mod aims to redo all the arenas in the game by making them more interesting and a lot harder (not meant for a new save). Kind of like Encore levels except it all takes place in the original levels instead of brand new ones (Use Configgy to switch between Nemesis and vanilla)
If you find any bugs or have other feedback (or maybe custom enemy ideas?) then dm me on discord @somebilly, also make sure to check that you have the latest version of SpawnerArmExtras installed (v6.0.1) since having an older version will also cause issues with this mod
Nemesis levels save your progress separately and they have their own rank requirements
(Introduced in 1-2)
(27 health) Fires 1 slow black hole at a time that constantly follows you. Requires you to keep track of its position and to keep moving. If you get hit by the black hole, the launcher will fire the next one 2 seconds later
I know that the black holes don't target you through portals but I don't know how to fix that lol
(Introduced in 1-3)
(30 health) A tall defense system tower that shoots series of projectiles which predict your movement. If you parry any of the projectiles in the series, the rest will become purple which means they're now unparriable and don't deal damage to enemies. The yellow orb at the top can be parried to deal 10 damage to the Watchtower, either with the feedbacker or the jackhammer. Trying to parry the yellow orb may be dangerous, but it helps to kill the Watchtower a lot quicker
(Introduced in 2-1)
(16 health) Fires 2 magenta beams back and forth, can't be whiplashed. When you get too close it either: 1) pushes you up if it has wings, 2) pushes you down if it has a crown, 3) damages you if it has neither. Go read the full description under SpawnerArmExtras
(Introduced in 2-2)
Idol-like enemy that enrages the target enemy until it's broken. If the target enemy can get enraged on any higher difficulty, then it will still enrage even on lower difficulties.
(Introduced in 2-2)
(15 health) Creates magenta shockwaves every few seconds (the shockwave speed, size and cooldown can vary)
(Introduced in 2-3)
Idol-like enemy that creates puppets of the target enemy until it's broken. The cooldown depends on difficulty. In specific encounters, the puppets may not die when the Puppeteer is killed. And the puppet spawning cooldown can also be different on a case-by-case basis
Currently the mod is in development, so only some layers are changed. I'll update it as I finish each layer (if it's been like a week or more since the last patch then i'm probably working on the next layer already)
I'll most likely make the first 2 layers of every act similar in difficulty to avoid everything getting hard too fast
Done (3/10) - 13 levels
Upcoming (7/10) - 22 levels
if you can p rank everything in Billion Nemesis on Billion Difficulty i'll be impressed
