I'm at the part after I push the washing machine down to something to make a ramp rise and ride my airboat to this place. This lady opened the gates for me and a black guy spoke to me. I read from some FAQ that i have to part the airboat and some guy would take me to see some map and fix a gun on my airboat but its not happening. I have the node graph error And I have the A.I Disable problem. Even if i reenable it, it doesnt work. Is there a particular place that I have to park my airboat? I tried talking to all 3 of the NPC, 2 human and 1 Alien holding a gun which i suppose is to be mounted to my airboat but they did not say a word, they all turned to look at me tho. I have tried reloading a previous save but the sam prob persists. How do i get thru?? I heard that there is a cheat for spwaning a airboat with the gun. What is that cheat?? And is there any hl2 save game editor or modifier?? !! HelPPPP!!
