Superhuman Summoner (Apocalypse LitRPG, Deck Building, Harem)

Warren thought he would never return to the sleepy mountain town he grew up in, but when his father passes away, he heads home to settle his dad’s affairs. He’s barely there for a day before an ominous spaceship appears in the sky. He can only watch with horror as the craft disgorges hordes of terrifying creatures onto the defenceless town. Just when he thinks all hope is lost, he gains the ability to control an alien magical device, allowing him to summon superhumans. Now, Warren can call forth godlike warriors, assassins, and supernatural gunslingers to fight back against the invaders. Each of the summoned superhumans is bound to him and will share his fate if he falls. But he’s not the only one with the ability to summon minions and he’s going to have to fight powerful alien squires if he’s going to retake his town. And if he doesn’t succeed, the human inhabitants will face a fate worse than death.
