It took me forever to get an Urbie assembled in my first campaign and career playthrough. Second career started me with an R60, and I had the same trouble as with the King Crab: Thing is too slow to bring that autocannon into combat soon enough. I found some success giving it a long range solution. Early career pilots miss more often than not, but at least this gets the mech shooting as it slowly enters the field. **Adjustments: Dropping armor and JJs lets you add an AC/5 in place of the AC/2 for greater damage, but at the cost of heat buildup. Adding another JJ does help with the slow nature of the Urbie. Also effective with LL and AC/5 Pros: More survivable than stock, works with both the R60 and R60L, heat efficiency is actually higher by two ticks if not using JJs. Cons: No shield arm, JJs only really usable for gaining elevation. This build shown using standard equipment. Using + or ++ helps with damage output, but keep this mech at distance.
