The Alternative Rooms Mini-Expansion is a set of 8 room cards that gives even more variability to the Solar Storm game. With each new room having its own unique power, the extra rooms in this expansion greatly increase the number of variations for the modular setup in Solar Storm. The Alternative Rooms Mini-Expansions is shuffled with the base game room cards in the game setup. If you place a room card that has the same name as one already present, discard it and deal again. The grid should be made up of 8 differently named rooms but may contain a mix of the base game room cards and the Alternative Rooms Mini-Expansion room cards. The Energy Core should still be placed in the centre of the grid as the ninth room. This mini-expansion is included in the deluxe version of Solar Storm.
