The Two Colonels: Making your way through a large, flooded room, you will be forced to shut a valve and then burn slime off a ladder. Climbing the ladder will take you into a room with the level's first workbench. Upon entering the room, go into a hallway to your left. The diary will be inside the locker at the end of the hallway. A tape can also be found here.
That rot keeps spreading, and the more slime accumulates, the faster it spreads. Our valiant defenders, though, instead of scheduling regular cleanups and sticking to that schedule, instead prefer to wait til the last possible moment when the worms appear, and then run around with their butts on fire playing heroes!
The interesting part though is that each time they send less men. The second team's chief said it was not a coincidence, that there is some secret project going on the old railroad, and they are throwing all they can at it, and neglecting us. We're far behind that thing on priority list, everything under the wraps. Come on, if you're going to invent shit, at least put some effort into it! Nobody wants to do anything, and that's the problem!
They all want to find a warm and quiet place, sit on their asses and do important things, like counting beans and stuff. No wonder that when they're giving out green stuff, there's always a crowd, but when it's time to burn the slime you hardly see anyone ready to take the task...
