I found it strange, that you need to unlock enemy types in the psykhanium (at least i guess that the unlocks are enemies). I am Lvl 10 with my zealot and i can’t even test, what weapons do good damage against a certain enemy type. I can’t test, where the enemies have their weakspots.
Basically, when i get a new weapon, i have to guess and trial and error during runs, at what they are effective at. In my opinion, this is not a good game design, since it makes the learning curve artificially steeper, when there is already a mechanic that could give me the desired information.
Cheers
