As a relatively new player myself, it took some stumbling around in the game to find out the following;
-Recipes can create unique variants
-Equipment gets buffed after heat level 5
Apart from those two things, the devs seem to want to keep the secrets of minerals, alloys and gate creation behind the curtain.
I also think the tooltips on equipment descriptions are somewhat vague.
For example, the Frost Gun or the Searing Edge should have a little box that looks like the "Health Bonus +x" or "Charge Time Reduction: X" that would say the percentage chance on hit to inflict Freeze or Fire status, respectively. (x% Chance on Hit: Inflict Freeze/Fire/Stun)
I come from WoW, which had some nice looking tooltips.
The charge effect can still be secret and not placed on the tooltip, only to be found as a result of experimentation with the weapon to keep it fresh and new.
This thread is for anything the devs should tell new players up front in the rescue camp. Post those things here.
PS: The wiki sucks. Needs more templates.
Just so you know, there are very little of us contributing to the Wiki (maybe 3?) on a regular basis. I myself need to get back into that habit once I get back from my break. The Wiki doesn't suck, it's just somewhat disorganized at the moment because new designs are being created for displaying certain types of information, plus the lack of overall information due to the constant releases.
PS: Why don't you help?
