Abomination (PC, 1999)

The United States has been devastated by a mysterious plague. Within 72 hours of its appearance on the East Coast, nearly every citizen in the entire country lay dead in its wake. 

Among the shell-shocked survivors that roam the land are The Faithful, a bizarre cult that sprang up even as the plague was decimating the population. Its demented ranks worship a mysterious entity called the BROOD and they believe they hold the key to immunity from the plague.

Meanwhile, deep inside a military bunker, Project Nemesis is called to action. Its handful of soldiers don't know why they've been spared from the plague's wrath but neither do they question their fates. Their orders are simple: using weapons and their own special abilities, they are to take back their city from The Faithful, find out where the plague came from and discover the secrets of the BROOD.

You're in charge of the Nemesis team in this real-time, tactical combat game. Heavily influenced by the X-COM series, it requires both strategic and tactical expertise to win. The player maintains several bases of operations and send Nemesis team members to dynamically generated battles in an effort to retake the city from the slimy aliens and their human slaves.

The tactical battlefields are an isometric, top-down view. The real-time action can be sped up, slowed down and paused to allow the player to keep up with hectic situations. Throughout the game, the player will collect weapons and supplies, expand the Nemesis inventory of technological goodies and uncover the secrets of The Faithful and the BROOD.
