Final Liberation: Warhammer Epic 40,000 (1997)

Final Liberation is a turn-based tactics video game. The game is best known as the first video game based on Epic, a table-top wargame set in the fictional Warhammer 40,000 universe, in an attempt to recreate the table-top experience on a computer as opposed to using it as a backdrop for games in other genres. As a result, the game borrows heavily in terms of rules and style from the table-top game, demanding a combination of luck and tactics necessary to succeed in game warfare. (wikipedia.org
