Im stuck. After the dead river, there is a place that Abe can walk around on top of several little sectioned-off areas with explosives littered about... I've collected 99 and uploaded them and that did something but I'm not sure what...then I have gotten back on top at the back of the complex and cant get threw to whatever........is this the end? what am I doing wrong? Thank you in advance for any hints or help.
