Get on Roof using invisible step:
If you go to the terrorist spawn in the back corner. The building with the c4 breach has an invisible step in the back.
You get on this almost the same as the awning in crossroads to get on the fish market roof. Once you land on the step, you
can jump to the roof.
Get in the Hidden House:
Once on the roofs, go to the series of roofs behind the breach building. Where you see a gap in the roofs, prone underneath
them and prone forward in. Go about 3 shingles from the end and lean to the left then rotate to your right. You will fall
right in.
Shotgun from roof to roof:
Required: 2 people, 1 shotgun
Once you get onto the roof using the invisible step,
follow the roofs behind the c4 building. If you jump all the way to the right, you will see a roof with a chimney. If you
prone to the right side of the chimney, you can shotgun people to the higher roof above it.
Get in wall behind Terrorist's spawn:
To get into the wall behind the terrorist's spawn near the barrel, you need to first get onto the back roofs. Go to the
roof with the chimney on it and go to the back right corner. Creep up to the edge just above the wall and slowly walk over
the edge. You will land on the wall which you can walk on, or you can keep walking to get in the wall, theres not much room
but its still a nice spot.
