I noticed that the first 2 Danger Missions, Legion of Almire and Compound 42 currently don't have bosses, while the next 2 Danger Missions, Heart of Ice and Ghosts in the Machine have bosses. The next 2 Danger Missions have bosses at the end of their second depths, so it's clear that the first 2 Danger Missions should have their second depth levels expanded to add new boss arenas and boss battles. I ask of you to update the end of second depth levels of Legion of Almire's "Inner Sanctum" and Compound 42's "Containment" to add the new bosses. I may have just the ideas for those bosses. Please listen, Three Rings.
Legion of Almire's Boss: Almirian Outcast (3 phases)
"Once a former loyal guardian of the kingdom of Almire, this hulky cursed Almirian Outcast was forever exiled in the depths of the Inner Sanctum, fixed to the stone grounds, preventing anyone brave or foolish enough to escape. If he comes across even a single knight who learns of Almire's secrets, he must engage in one last brawl before his exile continues... or not."
Attacks: Cursed Malice (Curse) (All phases), Fearful Flash (Stun) (All Phases), Tormentor's Blast (Curse) (Phase 2), Soulless Scythe (Curse, Shock) (Phase 3)
Compound 42's Boss: Experiment HRX Serial Number Z-0-A ( Or #Z-0-A, for short) (3 phases)
"Herex's abandoned creation, a horrid amalgamation made out of some scrap mech parts and a large living experimental acidic Jelly glop combined together. It was made to be the Crimson Order's great experiment, but due to severe malfunctions, it was grown out of control and was put away in the laboratory's cold storage indefinitely. It was discovered by one of the Recon Knights by an explosive accident. It's recommended to approach with extreme caution, for even it's single drop of acid can eat up their armor in a flash and it's huge strong robotic hands can crush knights with it's iron fists!"
Attacks: Summons Toxigels (Phases 1 & 2 only), Summons Toxilargos (Phase 3 only), Laser Eye (Shock) (All phases), Shockwave Slam (Shock) (Phase 1 only), Slime Hands (Slime) (Phase 2 only), Acid Glop Bomb (Slime) (Phase 3)
Those are the boss ideas for "Inner Snactum" and "Contaiment". I hope you'll update the levels to include the bosses, like you updated some levels to add in more rooms! Thanks for listening!
Actually if you had considered the end of both danger missions you'd find that the final levels of both C42 and LoA have arena battles, which also include stronger enemies, for C42 it's the giant gremlin scorchers and the giant toxoil, while LoA has Almarian deadnaughts.
