Thanks guys,,, I did watch some facility vids, turns out I was just switching weapons too soon.
I have another question now,,, though.
Is there any way at all to speed up the dialogue with Trev in the tank room? As is, it seems you have to kill 5-6 seconds at the end of the level for the objective with him to complete.
I tried shooting him in different spots, at different times ( like with Statue), but this only failed the objective
I doubt it's possible,,, but thought I would ask/suggest anyway.
Now I must sleep, but I'm sure I'll have more n00b questions for yas soon :P
