Alright, let's talk geography! Namely, the urban geography of HyperCity itself. Still working on the details, though I figure with all the explosions and reconstruction that are a daily part of life in this crazy, crazy place, I can probably play things a bit loose with those.
The chief feature when trying to figure out where one is in HyperCity is the highway that passes through the epicenter.
Called "The Highway", this ten-lane raised freeway (five north, five south), when viewed from the Official Map of HyperCity (or OMH, rhymes with "tome") enters city limits from the southwest corner, before curving straight north through the very center of the city. After passing through the center, The Highway curves again before exiting the OMH city limits at the northeast corner.
Because The Highway passes through the very center of HyperCity, it is the dividing line between the eastern and western sides.
Fun Fact: It is illegal to walk, climb, or otherwise not be in a working vehicle on The Highway within city limits. (Addendum: Rocket skates are considered a vehicle)
Anyone walking on the highway without official police escort will have a $1,000 dead-or-alive bounty placed on them effective immediately, to be collected by the first motorist to hit them with their vehicle.
Note: anyone with a previous criminal record are disqualified from bounty collection. Any such attempts of collecting a bounty should be considered a hit-and-run.
If you should break down on The Highway, do not leave your vehicle. Signal for a tow, then wait for one to be escorted to you by police forces.
Next, Main Street, and street navigation...
