Aeons Echo

Aeons Echo is a free-to-play, hentai-themed tactical RPG with a setting which blends elements of science fiction and Greek mythology.

The player takes on the role of a typical modern-day student who stumbles upon a portal to a futuristic fantasy world influenced by the Greek gods, where its female warriors are at war with hostile robots that kill their enemies by draining all of their energy through pleasure. A robotic girl named Lilin who is allied with the female warriors informs the student that he is the son of the mythical Zeus, and that he has been summoned to help them defeat their mechanical enemies and resurrect his father.

Before entering a level, the player forms a team of up to six characters and can choose which positions they will occupy on the grid. In each turn, the player can choose an action for one of their characters and which enemy they want to target (if applicable). Successfully clearing levels rewards items which can be used between missions to upgrade characters' skills and abilities. By using certain items on specific characters, the player can level up the character's statistics as well as improve their relationship with that character, unlocking exclusive story chapters and hentai scenes. New units are obtained via a gacha system where virtual currency is spent to obtain a random selection of new characters.

In addition to the main campaign, the game features a player-vs-player mode with leaderboards. Other features include an album where previously-viewed hentai scenes can be replayed, and a shop where more items and currency can be purchased with real money.
