You dont need to reply, this is just for those people who are confused about where to obtain a mech and how to get the mech parts added by this mod.

Down below where penguin pete is sitting is a sort of lab, factory, or hanger(whatever you want to call what it is). The penguin in that room can give you the quest to unlock access to your mech and to the mech tables. However for the penguin to offer the quest, you will have had to talk to esther to finish the quest "become space-worthy" (or something like that).

Furthermore, most of the mech part mods will simply add their parts to the mech part drop tables, which you get these drops primarily from Hostile ships. I hope this all helps.
