Man blocks are the size of the engine room, two one by one blocks high and three one by one blocks long.
Man blocks have shop items which can increase their health and the damage their actions do. Oddly, man blocks have to be in range of the player's steam power radius or they will not function, which is odd as the man blocks do not need steam-power to power them, unlike guns. The actual people who assist the player cannot be hurt, only the block can.

- The health upgrades for the man blocks did absolutely nothing in the first update of Steamlands. The second update fixed this glitch.
- On some screens on the walls of Nitrome Must Die, a repair man can be seen.
