There's a button that all normal empires get access to on the system screen. It causes a 25% happiness penalty and will cleanse a sleeper (while preserving your pop) after 5 turns, it repeats until it can't find any sleepers and shuts off if so. The AI seems to psychically know when to use this option.

Additionally, there's a researchable sleeper purge option, you can spend influence to kill all sleeper pops in the system (this will not preserve your pops). You can use it even if there's no sleepers and won't refund the cost if that's the case.

You want to be careful using a sleeper purge in MP, I trolled a guy into purging his entire population once. I have no idea how sleeper crazy the AI gets, but you should probably be wary in singleplayer as well.

You mean you removed that planet populations by killing your sleepers in it? That's neat.

So that purge options can be used to remove unwanted species isn't it?

The purge is for normal empires, and it kills any of your pops that are sleepers immediately, rather than making you wait for the round up. You don't get any control over who dies. The round up gets rid of sleepers without killing your pop, but takes time and only works on one pop at a time.

The choir themselves do have an option like that as a successful invasion outcome though, instead of pillage they get 'Abduct', which has all the effects of pillage but will turn any sleepers into umbral shadows at your capital, and if your capital is full it transforms them into dust and science. You get an acheivement for depopulating an entire system like that.

Need to try this out first, wish that we have some video guide/example about this mechanic.

What I'd like to know is how much infromation is avalible to the target empire of a hack or whatever. Are sleepers visible to them? Always or sometimes? Do they get an alert? Am I just being paranoid?

I've tried some testing in singleplayer, but unsuprisingly, I haven't been able to find and make contract with the choir yet.

Sleepers are invisible to the empire they are embedded in unless that empire uses the "Reveal Sleepers" action unlocked through a tier 4 tech in the Economy Quadrant.

They can, however, notice if any empire has 5 or more sleepers, as that will steal some Dust and Resources, which is visible in the tooltip.

Never seen the AI use it. Given how amazingly I trolled my unfortunate neighbor in that MP game I mentioned eairlier, that's probably for a reason. Also, it's a 25% penalty, not a 25 point penalty, it can screw you over if you're already treading water. (It's -2 keii per turn for hissho players, a very annoying penalty for having to deal with the consequences of such a dishonorable action on someone else's part).

I have, however, seen one of my pops with a sleeper marker when trying out a normal empire, no idea what causes that to spring up. Defensive programs? Luck? Do they become visible after a time?

A trace moving across one of your own systems will detect sleepers there. However, sleepers will not be detected in the system that starts the trace. If you want to dicover sleepers in a specific system, "Sleeper Identification" is your only option.

Ahhh, thanks for that info.  I was trying to figure out why I saw some, but not other sleepers.

This is really good information and might be something we could put in a tooltip somewhere in the game. 

We are working on improvements to the tooltips to be included in the next patch.

I see. Checking out the the tech tree again, I can also see that sleeper identification and sleeper purge are mutually exclusive as well. I can also see the cloak status of the system tucked away in the upper right corner above the system fidsi output, hidden in plain sight.

Am I supposed to be able to put Sleepers in place when not the Umbral Choir?

when will the next patch release

When I play the Riftburn I always put singularities on my own system.Now some singularities can add haking speed.Will the singularity make it faster for other empires to hack my system?

Cannot give an specific answer. Singularities affect hacking speed, but you should look at them one by one to see exact effects.
