After six playthroughs have found the following ten achievements either may not unlock despite requirements met or are suspected to be glitched. Also some of the descriptions are misleading. I indicate which category these fall into.
Squad Diversity - Recruit a soldier of each class (don’t have to be in the same game)
Gltichy. See my guide here:
I Can Do Everything - Use every character skill (don’t have to be in the same game)
Glitched and stuck at 95% progress despite using all skills even mutogs and vehicles
skills. Devs can verify which skills contribute to achievement.
All Possibilities - Complete all different game endings
Of the five endings, the “lose game” ending is not registering therefore progress
will be stuck at 80% regardless. The three faction and phoenix point outcome are registering.
Citadel Destroyer - Destroy a Pandoran Citadel
May not unlock despite repeated attempts. Post result screen says a lair was destroyed and
humanity breathes sigh of relief etc. This is despite research requirement for destroying a citadel being completed.
Class Creator - Obtain solders of each dual class combination (don’t have to be in the same game)
Another one that may not unlock despite requirements met. There are 21 unique combinations and 42
if you count reverse combinations such as assault / sniper as well as sniper / assault.
I’ve done all 42 and it’s still not unlocking.
Master Builder - build a facility of each type.
Glitchy or description wrong . Unlocked for me on discovering ninth and final Phoenix Point base. See my guide here:
All the Live Ones - Capture each type of Pandoran (don’t have to be in the same game)
Description wrong. Actually need to capture not just each type but each variant. See my guide here:
Master Manufacturer - Manufacture an item of each type (don’t have to be in the same game)
Need a full list of items to validate whether this working or not. So far no-one has unlocked it to my knowledge.
Scientific Rigour - Complete all phoenix research projects
Believed to be presently unobtainable, full research tree needed from dev team to verify
Master Scientist - Complete all research projects (don’t have to be in the same game)
Believed to be presently unobtainable, full research tree needed to verify.
It’s now publicised that the game has unobtainable achievements, there are actually 5 not 4, master manufacturer is the one missing (at present).
