Im in the hive and i've just had to sabotage the spore conduits.

I've done the first one, and then I made my way up the rubble and around to the next conduit which was in an opening, just to the right of the ship thing (the one where the water flows out of the pipe and down that hole in the ground. I've killed all the aliens in the and I have sabotage'd the conduit.

Now, I have no idea where my marker is trying to send me. I've looked around and around and cannot find anything or anyway out.

I think a door to the hive/ship was supposed to open but nothing is working. I reloaded and tried this about 3 times now and still nothing..

Anyone shed any light on this?

PS. I also fell through the ground in this area...

Make sure to kill all the enemies?
The bottom picture your stating at the marker but the map shows the point of interest a few leaps ahead of you.

Sorted, nice bug there.

Went back down to the bottom and found one of the conduits I hadn't damaged.

Anyway, upon doing that one, all the enemies came back and the other 2 conduits needed to be redone :s
