Final Release - Pixelate, #4

A tower defense game the size of an MMO. He defeated the Mountain Lord. He won. But the game didn't end, it merely evolved. Taking on the title of his fallen predecessor, Mountain Lord Konroh gets his final task: defend the spire at any cost. A whole host of new systems open up. Erstwhile villains now owe Konroh their fealty. He can reassign monsters to new zones, teach his minions new strategies, and beef up his fortifications to his heart's desire.
But everything come at a cost. To pay for it all, he'll need to kill players without getting personally involved. Because to harm a player before they enter his castle will incur penalties that could cripple Konroh's hopes of survival. And those players are coming for him. Defeat is inevitable when you're a raid boss... or is it? Final Release is the 4th and final book in the Pixelate series, a LitRPG fantasy series that follows the adventures of Arnold O'Connor as his digital self, delving into the secrets of a world that feels as real as his own body.
The Pixelate series will appeal to fans of classic JRPGs, World of Warcraft, and Lord of the Rings Online. It touches on themes of self and reality, style vs. stats, and how to kill dragons through the superior application of math.
