Forbidden Island Engineer's power?
From the manual:



Any character can shore up a tile that is either adjacent or underneath them. The engineer is listed as an exception because he can shore up 2 tiles per action. It doesn't indicate any other requirements or exceptions for the Engineer. It does distinctly say they must be for one action so you can't spread it around. 

Some think that you can shore up two tiles away:


  The group I played with argued that he could shore up two tiles in a straight "line". That is, one adjacent tile plus the one next in line, adjacent to that adjacent tile. So, shoring up a tile that has a tile between it and the tile he/she is standing on.


but the general consensus is this is incorrect. Nothing in the rules indicate that. The ability doesn't say he can shore up two adjacent tiles but 2 tiles which inherit the previous property of adjacent to the player.
