How to make the advanced Psi Amp?
I've been looking everywhere trying to find what on earth I have to do to make this thing buildable. I've already researched psionic (autopsied a sectoid), just finished plasma weapons, so my stuff isn't exactly low tech, but this thing still isn't showing up anywhere.

What do I need to research/build an advanced psi amp?

And before anyone goes "wait for the alien psi amp" its going to be a while before I see a gatekeeper, so that's not an option.

Researched both already. Still not showing up anywhere. Had this issue ever since LW2 1.5. Didn't seem to be an issue in the 1.3 version.

Here's a list from LW2 1.2: http://i.imgur.com/gVgX5dU.png. Advanced Psi Amp needs a sectoid corpse, 40 supplies, 2 alloys, 5 elerium crystals and 1 corpse.

Yeah, that's 1.2. We're on 1.5. A lot of things have changed. Also, I have researched both Elerium (A long time ago, I have plasma weapons) and psionics (Again, long time ago) and a ton of sectoid corpses, elerium, alloys, supplies, cores, intel, recruits, everything. There is still no option to build/research the advanced psi amp anywhere. There is no mention of it anywhere.

In the end I just used the console commands to deduct the resources and give the amps myself. This has been an issue ever since I started 1.5. I'm convinced that something is broken in the INIs somewhere.

Could it be developed through the Proving Ground?

Not from what I'm seeing here. I've done numerous proving ground projects, but there doesn't seem to be anything related to psi amps, or psionics in general.

You definitely have a bug. I've made it recently in at least two play throughs (1.5 and LWotC).

Reinstalled LW2 recently, full reinstallation at that. Bug is occuring both before and after. I honestly can't figure out why.

You have to perform the Gatekeeper Autopsy, then you get the possibility to build Psi-Amp in Engineering/Weapons as Squad Upgrade. If you do it, then your Psi-Operatives will get the Psi-Amp as secondary weapon - so it means, you have to have some Psi-Operatives, so you have to build the Psi-laboratory first and train them from some rookies.
The ALIEN psi amp, yes. But I'm looking at the ADVANCED psi amp, which should be showing after the sectoid autopsy.

OK, sorry, I confused myself... But if I look into the sectoid autopsy report, I see there is possible to produce mindshield, not advanced psi amp... Do you have Psi lab and some Psi operative trained? I really cannot find, when I got the possibility to build advanced psi amp... But I know, it was before I had to be able to use alien Psi Amp...

See, that's the thing, according to the official information on the 1.5 LW2 research tree, the advanced psi app SHOULD be unlocked via the sectoid autopsy.

If your not seeing it either, that means we've got the same issue, or that information is wrong.

So, I figured it out, it was after Psionics research, then I was able to build Advanced Psi Amp. But if I look now on the report, the Advanced Psi Amp is not there, so I guess there can be some issue in the game. It was there (in Report about Psionics) couple weeks before at the time I saved the game before... So Possibly I had something more, which I have invented before too to get Advanced Psi Amp. Or there is a strange error, which sometimes prevents you from inventing it at all... Or is it a feature? :-)

No, that definitely sounds like an error. Or more likely, an oversight of some kind. Possibly an bad ini line somewhere.

But I'm not too familiar with how long war 2 handles its INI settings in regards to items. In theory, you would have to trawl through the INIs to find the research that is SUPPOSED to unlock the advanced psi app (which should be sectoid autopsy), then, through trial and error, figure out which specific line needs to be re-modified to actually unlock that function.

That, or find the advanced psi app line in the INIs (one of them anyway) its research prerequisite, and modify one of the numbers (to gods know what), or one of the resource values for the advanced psi app (different line, again, no clue which number to modify, or what to).

That's all under the assumption that the INI values corrospond in any similar way to Long War classic, which they may very well not.
