Defender's Quest: Valley of the Forgotten [Red Smoke Cover]

Defender's Quest is a Tower-Defense/RPG Hybrid. It focuses on three things: tactical depth, customization, and story.

The battle system builds off of tower defense, with individual characters taking the place of towers. Each character levels-up, learns skills, and equips gear individually, allowing the player to customize their battle experience and strategy. The overall game structure is similar to “tactical” RPG's, but with a real-time battle system. Game speed is adjustable, and commands can even be issued while the game is paused.

It also features an engaging, character-driven story written by an actual English major! The story strives to be fast-paced, snappy, and always relevant to gameplay with minimal exposition. Finally, it's got options and accessibility settings out the wazoo, so that you can have the best possible experience!
