Those sharks creep me out.
I was in the minisub and just had completed the nuclear waste collection mission when I saw a red blip on the minimap. I looked behind me, and sure enough, there was a shark. I gunned the sub for all it was worth and headed north, planning to ditch the thing where-ever I could find a beach close to the road, either to jack a vehicle or call a cab. That sub is just too slow for viable transport.
(Good way to escape a 5-star rating, tho' - they can't catch you when you're sitting 300 feet down!)
I kept an eye on the minimap and the shark was still there, right on my tail. A visual check confirmed it. I thought, "Uh-oh, I'm being stalked by Jaws." Finally found a beach and ran the sub up on land, jumped out of it, and looked at the ocean. In less than 5 feet of water, about 6 feet away, the shark was circling.
I whipped out a silenced carbine and took care of it. Shark Fin soup, anyone? Or, perhaps some grilled fish steaks?
That was just creepy. I was planning on scuba diving, but now I'm not so sure. I think I'll just explore the Alamo Sea, that's gotta be shark-free.
