Okay, I was torn between the orange ramp and the milky goo for a catchy thumbnail. Milky goo won, because apparently if you spray the walls with the milky substance, you can create portals on the surface as a result.
New mechanics, I'm loving it! I wonder what else they can do with portals. Maybe some ivy bridges that grow through, or something like that. Though that would render walls useless. Maybe they can have a gun that shoots four portals instead of two?
