When you get on the lake here's a few Do and Don'ts
when you arrive at the lake you'll see a cut scene where they toss the one of the guess you came with intot he water than a moment later he's eaten by this giant water lizard, my brothers call it a ta-pole, what ever you want to call it, to get a little jump here's what you do, save before attempthing this.. when you have saved go tot he dock instead of getting ont he boat shoot a few of the little fish, and wait for a good surprise..
when you are fighting the giant lizard of some sort, and you've come across the floating logs in your path, dont panic, simply tap your main moving controller ( aka joy stick )
and best of luck..
after you've finished killing it it'll be dark out and a bit more scary.. another trick for an enemy near by.. once you are able to save on the other side of the lake, feel free to go and visit to merchant guy and buy what ever you like, after wards save again be for again attempting this attack...
once you've saved go back to the same dock where you first got ont he boat, its not far just across the lake but save first incase you die.. when you arrive at the dock you should see the same house where you saved before, down the path to your right will be two white wolves.. when you get far enough you will see a cut scene of them, right after wards run like crazy back to your boat, don't turn around yet of they'll get you, once you get to the dock get ont he boat and they should be rightbehind you on the dock, but no worries they'll be stuck there, and than harpoon them, it only takes 2 hits to kill them, but if you aim correctly and if you close enough, just dont go to close where it say's get off becuase I wasn't that close... after wards grab the loot.. if you you only killed one than there's one more.. go back downt he path but not to deep into it and pull out your sniping rifle and snip it.. you can't kill it with that so once you've hit him, run back to the the boat and repeat the steps you did as killing the first one... from there on out Good luck witht he game..
