This way, when I build out, I can build a full three-room power plant and three-room water treatment plant. I like to start by putting a one-room power plant on the left side of the pre-built elevator at floor -1, and one water-treatment plant on the right side.

You won't have the CAPS-in-game money-to build these three-room areas off the bat, so here's where the planning comes in: You start the game with two elevators-on floor zero and floor -1, respectively: On floor zero, you have a one-room living area and a completely empty lower floor.Īccounting for an elevator at the very end of the -1 floor, you can build one three-room area, the elevator, a three-room area, two-room area, and another elevator. This is highly recommended, and one of the best ways to get a balanced, bustling population early. You build rooms in the game in one-room segments, but don't let those tiny rooms fool you - you can build up to two more copies of that room next to it to combine that section of the floor into one giant area.
