SC21 SCAVENGE

     In Open Ocean: East, travel East from the Coast Guard HQ to find the
     location of this challenge.  You are given a time limit to find a specific
     number of tires.  When the challenge begins, there are three concerns
     other than the time limit that you need to consider.  Directly below you
     in the North end of the pit-like area  is a Seeseaker that will siphon off
     your "Hunger" meter, there will be a mini-sub nearby, and a Coast Guard
     Heavy Raft type boat above you.  If you get too close to the surface they
     will open fire on you.  You can do this challenge without destroying
     the boat, besides it will just reappear in each additional level of the
     challenge, so I don't normally kill it.  Also the mini-sub will drain your
     "Hunger" also but it's like a double edged sword.  I followed it trying to
     catch up to destroy it, and while following it I seemed to find more
     tires.  I'm not saying it leads you to them, but when I don't destroy it
     right away, I tend to find the tires more easily.  However, I do recommend
     destroying the Seaseeker at the bottom of the "pit" where you begin.
     There really is no easy way to describe the locations of all the tires.
     At this time I am working on a location map, which I'll post in one of my
     future updates.  Just slowly swim a circle around the pit, going in be-
     tween, over and around any rocks or mounds that you find.  The first level
     is the hardest actually, it seems that in the last two levels the tires
     are easier to spot, and there will be more of them.  You will still have
     to look for them but you should find them easier.  A lot of the tires are
     partially buried into the soil on the bottom, but you should see them
     sticking out, and don't forget, after swiming once or twice around the
     pit, reverse direction because the change in perspective might allow you
     to see something you missed earlier.  Also, in the later levels, a lot of
     the tires will be where you found them in the previous level, so you only
     have to find a few "new" ones.
