We know that Pandora Gates remake themselves if blown up. This means that holding onto them is... Problematic at best. The Ultimates already control the Discord gate, they merely allow Go-Nin to pay them for the privilege of saying that Go-Nin do. Anybody who thinks that Go-Nin has any real control over the Discord gate if the Ultimates decide to push their own claim (which is based on boots-on-ground instead of records-on-file) is delusional. An attack on the Vulcanoid gate aimed to seize the gate itself is likely doomed to fail; such an attack would almost certainly be two-pronged, first from armed Ultimates posing as Gatecrashers going hostile coinciding with an Ultimate attack from the far side of the gate, but after the attack in 9 AF, TerraGen almost certainly has the most tried-and-tested Gate defenses, with heavy backup on-call. They might sieze control of the complex for a period of time, but it would be a smoking ruin by the time the shooting was done. Best-case, they get control of it for a week or so before TerraGen can get an army there, but that's a very, very long shot, with a high chance of failure, and a not-insignificant chance of a WMD counterattack through the gate. The more realistic scenario is that the Ultimates remotely connect to and sieze control of the gate, just long enough to kick a nuke on a 3-second timer through the gate. That'll take the Vulcanoid Gate out of action for a while (I can't, right now, seem to find exactly how long the Discord gate was down when it was rebuilding itself.) An attack on the Martian Gate is absolutely doomed, given that the PC can and certainly does station a large army near the gate, with heavy combat vehicles and morphs, far larger than could be feasibly brought through the gate, and far more numerous than could be feasably mustered by the Ultimates, even if they concentrated all their forces on the one gate. At [i]best[/i] they could temporarily take control of [i]part[/i] of the gate complex, but their time in control is going to be measured in minutes, not hours. The worst-case scenario is a full-scale Pathfinder [i]counter-invasion[/i] that they'll be hard-pressed to fight off, with the runner-up bad scenario involving a counter-WMD attack Again, the more likely scenario involves kicking through a nuke to deliver a blindside sucker-punch. An attack on the Pandora Gate itself might work - again, temporarily. The fractious nature of the folks surrounding the gate itself would potentially allow for Ultimate social engineering to set everyone at each other's throats, causing the locals to believe that one of the other factions nearby has gone crazy, rather than presenting a unified threat. The best-case scenario for the Ultimates usurping the Pandora Gate involves a comprehensive social engineering campaign getting the anarcho-collectivists and the anarcho-capitalists to go all-out with each other, and dragging Gatekeeper down with them. The matter [i]will[/i] be settled decisively when the Titanian Navy shows up, along with whatever other Autonomists nearby unfucked their heads, decided to put their own differences aside temporarily in the name of crushing the balls of the overhumanist bastards who took their shiny, but potentially the Ultimates could have a few [i]days[/i] in control of the gate. The better question is what would they [b]do[/b] with it? Potentially, they could carve the section of Pandora containing the gate itself off of Pandora, and drop it into Saturn itself. If they were ready with large antimatter or MH rockets on the far side, and were [i]dead certain[/i] (IE, having already tested this previously on some exomoon,) it could work, they could maybe do it. Of course, cutting off a piece small enough to simply drop into Saturn raises the possibility of a Titanian interception-and-recovery mission which would see the Gate permanently installed on or above Titan itself; this may actually be a complicated Xanatos Gambit to cause exactly that to happen. Again, though, the more likely scenario involves a WMD sucker-punch. The Fissure gate is the gate the Ultimates are most likely to be able to take and hold by force. Ultimates stopping by isn't uncommon, and while the Anarchist ideals mean that literally anyone and everyone is a potential hostile combatant, the lack of a central authority in a crisis will hinder them. One thing they do have going for them is that their defenses are going to be novel; Autonomists from all over have cooked up unique weapon systems for them and provided them, and they do not discuss them, so any mission to storm the Fissure Gate is going to have to overcome challenges that simply cannot be predicted and prepared for. When facing the forces of Pathfinder, Gatekeeper and TerraGen, it's a relatively simple matter to get an idea of what kind of front-line combat units you can expect and extrapolate from there, and extrapolate from the Ultimate's own special forces to get an idea what sort of enemy elites they may face. With Autonomists? There's no telling what they'll face. I would say this is nearly a toss-up, but I'd give the Ultimates about a 55-60% chance of taking and holding the gate in an overt show of force. If they succeed, nobody will be able to mount a relief mission in any kind of reasonable timeframe, and by the time they do, the Ultimates will have their defenses in place, meaning any attack will pretty much have to either be aimed at completely smashing them and destroying the gate in order to retake the territory, or will, itself, have to be another two-prong attack, probably launched from the Pandora Gate by the Titanian military, supported by whatever Autonomists could get there in time with it. This, of course, will have the problem that said attack will be predictable, since they'll see the outside forces coming and can reasonably time their defenses inside. So, really, the "Ultimates take and hold the gates and lock Transhumanity in the Solar System while they go on to become Overhumanity" plot idea is pretty dumb. I'm not saying there aren't Ultimate warhawks who mil-wank to it, but it would pretty much be the only thing short of the TITANs returning that could successfully unite all of Transhumanity in a more-or-less common cause. Perhaps that's actually their plan all along, and it's a huge Xanatos Gambit to make the Autonomist Alliance, the Planetary Consortium, the LLA, Morningstar, and Firewall band together for the express purpose of kicking their ass. But otherwise, it's a really damn dumb idea.
