What we've got here is...failure to communicate.
I finally took the time to decipher Cycle's attempt to describe a location in Mombasa Streets. Please look at the attached map.
The point labeled "02:28" is where you have to be to see what you see 2:28 into the
Desperate Measure ViDoc. It's in
District 09 otherwise known as D09.
The point labeled "TGSD 0" is the
TGSD which leads to a large interior portion of a building. I can only assume that this is the "casino" being referred to.
The point labeled "TGSD 1" is a TGSD inside the building which is locked.
The point labeled "TGSD 2" is a TGSD inside the building which is unlocked. When you open it, you find a small room with a dead marine, two frag grenades, and an assault rifle.
Please note that D09 is NOT feature in the video I referenced earlier despite Scat's response that it's "very close". The video ventures into a mirror-image version in D00 which is about as far from D09 as you can possibly get in Mombasa Streets.
So now that we have this all cleared up: what is the question?!? Perhaps:
Q: Can you get past the door labeled "TGSD 1"?
A: Yes, it bumps out. Behind it is a small room with nothing except two small NMWM trash cans on the NW side.
To bump D09, follow the instruction on the
Bumping District 09 Map.
I hope this clears things up.
