Okay, spoilers! Inspired by Zespri checking language files for anti federation alliances, I decided to check ultimate weapon stuff to satisfy my curiosity. I still have no idea how to hell to get races build them, I just made playthrough on starting year 50 and managed to almost research time travel but nobody was ever capable of building it
Peltian Asteroid Perturber: Unique Peltian ultimate weapon. Every 30 to 90 months, causes an asteroid to rapidly change trajectory and fly at another race's planet or outpost. The effects on planets are devastating, ripping through defense armadas as well as killing massive numbers of the populace.
Evucks Psyops Broadcast Tower [race]: Unique Evuck ultimate weapon. Causes the [race] to descend into a state of perpetual internal war, tearing themselves apart until the tower itself is destroyed.
Burlust Psyops Virus Development Center: Unique Burlust ultimate weapon. Causes ALL races in the entire solar system to go absolutely crazy with bloodlust, and be locked in the Warlike stance until the virus center is destroyed. Being in a warlike stance doesn't mean that a race will immediately be at war with everyone, but it does make conflict overwhelmingly likely and frequent.
Skylaxian Cyberwarfare Facility: Unique Skylaxian ultimate weapon. Emits an advanced self-replicating worm that causes all non-allied robotic races to descend into a state of perpetual internal war. The worm depends on the cyberwarfare facility for continual evolution, however, so if the facility is destroyed then the robots will recover.
Thoraxian Search And Destroy Command Center: Unique Thoraxian ultimate weapon. Every 30 to 90 months, launches a powerful Thoraxian Hunter Fleet, which seeks out and destroys pirate bases... and then you, personally.
Acutian Industrial Sabotage Launchpad: Unique Acutian ultimate fiscal weapon. Every month, the Economy for every non-allied race drops by 1. Perpetually, unless the launchpad is destroyed.
Boarine Isolation Shield: Unique Boarine ultimate defense system. And absolutely impenetrable, invisible shield encircles the entire planet, protecting the planet's surface from all attacks -- ground attacks, bombings, you name it. Does not protect Boarine space armadas, however, since they are outside the shield.
Okay, first thing, holy crap ._. These are all so powerful that no matter they are really rare... And that makes me want to seem them all even more so.
Though, curious that Skylaxian weapon only target the robots ._. Huh. And Boarine Isolation Shield seems like unbeatable since how do you defeat them? Reminds me of the shields from Star Control II that Ur Quan set up on their conquered planets... I guess it'd be cool if Boarine would become after building the shield non factor in game, like since they isolated themselves from other race, they aren't threat so you can win the game with federation if they are only non federation race left and have the shield...
Thoraxian weapon doesn't sound like it will actually affect other races ._. Does it cause huge has swarm of ships to fight player? That'd be cool to fight
