We've made a huge amount of progress Sunday, let me break it down for you.
First, we should dissect the map.
Dull Blue: CT Spawn
Cyan: CT Lobby
Yellow: Lower Tunnels
Grime/Dark Green: Lower Mid
Yellow-Orange: Upper Tunnels
Green: Upper Mid (note the connector connecting blue and green is not done yet and will be finished with that)
Orange: T Lobby
Red: T Spawn
Unfinished (we didn't work on these areas yet)
White: Offices/Staff
Blue: Security
Now for the screenshots.
Doors connecting Upper Mid (by the Cafe/Lounge) to Lower Mid, which also connects to Upper/Lower Tuns through the passageway.
We finished the back area by the screenshot above, it's an "exit" (luckily for you, a dead end).
We spiced up the hallway connecting Upper/Lower Mid to the Tunnels area.
Continuation of the Upper Mid main hallway.
Eventually, it splits into 2 routes, one to the left to go to the T Station/Spawn area, the right to the T Spawn to office area. We'll go left and loop back around right.
Left stairwell up to the T Station.
Pics of the T Station, it connects to connects to T Spawn and Upper Tunnels.
T Station-T Spawn connector.
T Spawn area, stairwell is barricaded and they spawn right by the barricades.
Going into those double doors loops us back around to the Upper Mid crossroad.
