[Eve Online/Mass Effect] Reaper invasion

The Reapers have begun an invasion of the eve galaxy starting in the Eve Gate system with them heading for the Amarr system. Word spreads to everyone including the alliances in 0.0 causing them to form an alliance together. How does the war go, who wins.

The Reapers smash the shit out of the first empire they run into. They come from nowhere, the biggest of them have Titan-equivalent beam weaponry, their mass-effect shields are tougher than anything in Eve, and due to the way they bend physics, they maneuver *way* better than anything their size has a right to. Their reactionless mass-effect drives are comparable to top-tier Microwarp drives, without any of the signature drawbacks.

But Eve has an incredible industrial capacity. They don't outclass the Reapers, ship for ship, but a hundred or more fully industrialized solar systems can churn out a *shitload* of ships. They quickly learn what works okay and what doesn't against Reaper shields (bad: kinetic, good: thermal). The remaining three empires, recognizing a huge external threat, form a working treaty to push out the Reapers. The independent corporations, recognizing a gold rush of salvaging Reaper hulls, chip in with enthusiasm. The allied Capsuleers can reincarnate in cloned bodies, and do not need to fear death as they send wave after wave of moderately effective cruisers to blast away at the Reapers.

The human losses (and *expenses*) are horrific, but it's a great time to be a manufacturer or salvager. The Reapers retreat after suffering moderate losses with no gains. Eve space celebrates for a week, and then goes back to political in-fighting over disputes about Reaper salvage, insurance, and who gets to reclaim and rebuild which Reaper-wrecked territory. Corporations fill the power vacuum next to the few Amarr territories left, Eve space settles back into a dynamic equilibrium. CONCORD keeps a Reaper watch running, to sound the alarm and call the alliance back together if they rear their space heads again.

All that salvaged Reaper stuff? It's still alive. All of the top researchers and trophy-taking CEO's analyzing the leftovers are gradually subjected to the Reapers' Indoctrination effects. People successfully reverse-engineer the mass-effect FTL drive, and in the process, top empire & corporate figures are turned into Reaper sleeper agents. Lots of people realize what's happening and/or notice active Reaper nanomachines, but they're up against sleeper agents and perfectly rational competitors who think it's a BS conspiracy theory. Some null-sec corporations fold into cult-like sects and disappear from the galactic scene, flying their new ME FTL drives into dark space in search of their gods.

There are a lot of shrewd, un-corrupted people who isolate themselves from Indoctrination, but hardly any organization gets by without *any* sleeper agents.

Months later, the Jita port authority shuts down its automated defenses and enforces a hard blockade on its warp gates. Atomics go off on every station moments before the Reapers come back for their second attack. The defense is disorganized, sensor-jammed, sabotaged, and at least one capsuleer out of every twenty turns against humanity. Billions die, against two Reapers destroyed.

When someone in a pod is killed, their clone is still indoctrinated wherever it wakes up. Reincarnation policy has to be seriously re-evaluated. Some organizations begin outright prohibiting clones that have had extensive Reaper contact, others quarantine them. And, of course, sleeper agents in positions of authority abuse those quarantine procedures to lock out hundreds of un-indoctrinated pilots.

Coming right behind a massive wave of industrial sabotage, terrorism and intentional dereliction, the Reapers tear apart the empires. It takes a while, and there are losses, but Eve can't fight them back without a very organized defense, and the fear of Indoctrinated authorities or allies, where it is real and where it is imagined, makes that impossible. All the manufacturing capacity in Empire space is either destroyed or appropriated, and once the Reapers have space superiority, the trillions of people planet-side are processed.

The last survivors of humanity, months later, are distant null-sec corporations, in far systems and hiding in wormholes. All it takes is one indoctrinated member - or brief contact with some indoctrinated transient - to call out their location and bring a hundred Reaper capitals in a minute later. Fully-indoctrinated groups roam the far systems pretending to be refugees, and bringing hot laser death on anyone who doesn't shoot on sight. Unable to trust each other (with good reason) the surviving organizations are not able to fight back in any meaningful way. It might take years for the Reapers to track down the very last nomadic outpost jumping through wormhole space, but humanity loses.
