how do u do mission that one in the beggining HELP

ok i just met with eva for the first time and we just ( i just) defeated the ocelots for the second time. i have to go to a crevice. wenever i talk to the Zero mann he just says go north, and theres a cave in the crevice. i cant find the dang old crevice. Help.

plesae help

From the abondoned factory, go north to an opened gate(Eva opened it during the cut-scene after you defeat the ocelots). You end up in a new area. Keep going north, you then come to a swamp. Go past the swamp to a new area with electric fences. Make your way past the guards and fences, then go north. The next area is an enemy outpost/base (the helicopter is here). Go through the base (north)to the next area(ocelot boss fight). I'm thinking about this from memory, so look for different walkthroughs on this site. Hope I helped!

Snake automatically goes into the crevice after the boss fight with ocelot.
