Earth Expects is a highly detailed set of tactical space combat rules which emphasise skill over firepower. It is well suited to playing battles from duels to squadron actions; because of the high level of detail large fleet battles can be slow to play and therefore optional rules are provided to speed play in these games. Earth Expects is designed to represent battles within the solar system between ships capable of manoeuvre at sub light speed. No aliens have been encountered; battles and wars are fought between human factions as they have been since before the dawn of history. Modification for use in a galaxy spanning campaign is straightforward.
