-Area 51 will replace the Dungeon, Skeletron will be replaced with Skalientron (Skeletron+Alien, has 100x the stats of the former, even worse in expert mode with about 1,120,000 total health. Even Skeletron Prime becomes Skalientron Prime), the skeletal enemies of the latter will be replaced with aliens (I am not referring to Martians. but the stats of said Aliens are 100x higher than the Crawltipede), Dungeon Guardians are replaced with the heads of Skalientron (Area 51 Guardians that have 999,900 HP, DMG, DEF and SPD), The Cultists being replaced with "Area 51 Raiders" (possibly people wearing the Angler's set sans his hat, SWAT helmets, Ankh Shields and Sniper Rifles, their leader wears an Eye of Cthulhu Mask. All of the members have the ability to "Naruto-Run" with the highest speed possible, faster than the highest speed reached by Terrarians), and all of the weapons are replaced with laser forms (for example, the Muramasa is replaced with a laser Sword from Fortnite: Save the World).
