About Sandtraps, need help!

[[^Demigod]]

I am stuck in sandtraps, in the cave where there is a man saying this is the only way to nova prospekt, i cannot get through that door and i use the "liftingobjects gun" to get over the fence and down to the two trees lying in front of the cave. I CANNOT get over those trees, i tried but it doesnt work, anyone know what to do?

It does the same to me. Friends told me: the alien who opened the big monster and gave you the ball should have lead you to that door and open it for you. It seems to be an AI bug.

I also tried to recomplete the level from the beginning - nothing has changed. :rolling:

did you complete the short bug-bait tutorial that the vortigaunt puts you thru?

Solution to bugs

Just in case anyone comes across this thread as I did, there are actually four bugs to this part of the level which I managed to trigger, these are the solutions I found:

Bug 1 - Vortigaunt stands by white door, doesn't approach Antlion Guard:

With this bug the Vortigaunt just stands by the white door and continues to say "follow freeman" and "freeman must follow". This seems to happen when the Antlion Guard is not killed close to the door. The only solution to this seems to be to redo the battle with the Antlion Guard and make sure he dies close to the door. It's best to let the guy operating the gun turret above the door to do most of the work, this seems to draw the Antlion Guard closer to it.

Bug 2 - Vortigaunt releases pheropods from Antlion Guard but doesn't move:

This bug seems to be triggered similarly to bug 1. Sometimes the Vortigaunt will eventually approach the Antlion Guard after some time, even if it is was not killed close to the door. However after releasing pheropods the Vortigaunt doesn't do anything and again continues to say "follow freeman" and "freeman must follow". The solution to this is the same as Bug 1.

Bug 3 - Vortigaunt releases pheropods, opens door but then blocks it:

Even if you kill the Antlion Guard close to the door, the Vortigaunt releases pheropods and then opens the door for you, you may still trigger another bug. As the Vortigaunt heads towards the door and opens it for you it will then stop and stand in front of it, blocking your path. The solution to this bug is to stack a few more crates on top of the ones to the left of the door and then drop down in front of the Vortigaunt, allowing you to continue. However using this solution will trigger bug 4.

Bug 4 - Cannot proceed through gate to "nova prospect" or through log gate:

This bug is triggered by bug 3. After opening the door the Vortigaunt is meant to follow you and open the gate towards "nova prospect". It will then give you a bug bait tutorial before allowing you to proceed through the log gate further on. The solution which worked for me is to save the game after going through the door and then load the saved game, the Vortigaunt should then start following you.

Hope this helps a few of you.
