X is where they start, brown is mountains with twisty caves going thru them, blue is water, green is normal land, dark green is forest, and red is a volcaino (the tributes don't know it's there) more info here: Yes, you start on the mountain. Dont stay on top of mountains too long though or the altitude lack of oxygen will kill you. Trying to fight on top of mountains takes more breathing and will almost always kill you instantly. There are caves at the bottom of the lake that contain powerful weapons if you can make it thru... (Lots of mutts there) and in the center of the volcano there are some sick hiding spots plus its rigged with tnt :P BTW the tributes do not know this!
