On Arms Race shoots, you can jump on top of that the roof of the big building near T spawn
On Safehouse you can jump from the roof near the barn in spawn to the roof on the house and then jump into the secondary room on the second floor
On Baggage you can stand on the edges of the pillars outside of spawn
On Lake it's possible to get on top of the barn near CT spawn, and it's also possible to get onto the roof of the big red building
Arms race maps are very interesting mens)))
It's also possible to wallbang from the back of the barn to the otherside past the boat, which is possible to get in on Saint Marc.
You can stand on the middle corrugated iron thing in mid in shoots, and it's also possible to get stuck in the ceiling
On the same barn in Lake you can get on to a little thing sticking out of the barn and look down towards the T spawn which is useful if you're using an auto-sniper
