Minesweeper

Two of the team members sit inside a tank with a gunge pipe above it. The tank is activated by pressing one of the four dangerous squares on a four-by-four set of pressure pads on the room's floor. It's up to the two free team members to uncover the twelve safe squares by following the rules of Minesweeper, each safe tile displaying the number of dangerous tiles next to it.

It's Minesweeper.
