Title: A question about the tech tree requirements
Post by: Ted on March 07, 2025, 07:40:01 pm
This is the tech tree I'm looking at:

I have already researched Fusion Torch, and it's power cell.  Does that mean I already have Alien Engineering Secrets?

I don't think I've ever gotten a popup after researching something saying I've discovered that. 

The reason I'm curious is because I REALLY want Alien Gravity Generator & Delta Radiation, (for better weapons). 

I had thought the dashed lines were pre-reqs before you could research the next item, but now I'm not sure.  Otherwise how could I have researched Fusion Torch?

The only requirements for Fusion Explosives and Antimatter Containment appears to be Alien Engineering Secrets.  How come I was able to research one, but not the other?

Thanks in advance for the help.

This tech tree seems to be for FMP 1.7. Are you actually playing that?

More recent FMP (3.6 or so) doesn't even seem to have Alien Engineering Secrets - the tech topics pop out of Alien Engineer/Leader/Commander interrogations at random, similar to X-Com Files. 


Also, this should probably be in the FMP thread (https://openxcom.org/forum/index.php?topic=2027.0).

Sorry, it turns out I'm on FMP 3.3.  Obviously I haven't downloaded a new version lately.

Is there a similar picture for whatever the tech tree looks like on the current version?  I doubt I'll download 3.6 in the middle of this playthrough, but I'll try to remember to do that before the next one.

I don't think there's a new tech tree image. Meridian would know, I guess?

But you can use the in-game tech tree viewer to search for techs and chase requirements from one tech to another.

I didn't create any since v1.7
