Hi All,

Freeman stand on my Left side let me give u pheoman Pods that will help you for further preceddings. Then the alien fires green electric rays on the dead Alien and after 5 secs he asks me to go and collect that weapon.
The Alien then run back to his door and now am stuck where to go .

The location is a Sea Beach with mountains around there is one door in between the mountains with a Big wall and at the top of the wall is standing a human with a gun which helped me to kill the BIG ALIEN.

I will soon upload the snapshot of the Location wher i am

Please help me

I figure your in the level Sandtraps and you've just killed the antlion guard. You should be able to follow the alien through the door. If not, I guess you'll have to restart the level.
