You seem to be new to this site! Welcome! Lol. Blood Fire and Forging101

 

I seem to be having a problem with this, I can merge the fence wall under, and place a grav lift on that. But when I push myself under the map I end up dying.
Anything I'm missing here?

 

press up on the d-pad as soon as you get under the level.

 

I do that, but I only get around 5-8 seconds max before my monitor decides to blow up. Can I move or do I have to stay stationary?

 

you can move i suggest you move up towards the floor rather than stay stationary and that shuold help you without dying.
