Can I design a new mech from scratch for use in gameplay?
You may be a mechwarrior but only the very special soldiers own their own mech (and I don’t mean Timber Wolves and Atlas here; think Wasps, Stingers, or other ancient, light-weight and well used mechs), those who have had their mech in the family for generations. No the truth of the matter is unless you are a mercenary units CO you don’t own your ride! Your CO owns both your gear and your soul till the end of your contract, or the death of one of you. And that is thinking on the bright side soldier! Thanks to Lieutenant General Kristan Dagley, Military Hardware Broker for this answer.
