LambdaRogue is a rogue-like role playing game set in a strange underworld. Men and the species of Drekh'nar once lived peacefully together on Earth, both not far away from reaching the stars with spaceships. A misunderstanding led to war before these dreams could be realized. After a long and bloody battle, a peace treaty was created, forcing mankind to go underground. Mankind has lost the most of its technological knowledge, but Ahna, a priestess, is searching for the Book of Stars, which could bring humans back to the surface and beyond. And you are Ahna's agent.
Hydra Slayer is a Roguelike game focused on one thing: slaying Hydras. It is inspired by mathematical puzzles about brave heroes slaying many-headed beasts. Since each weapon can only cut off a specific number of heads (no more, no less), and then the Hydra regrows some of the lost heads, to defeat each Hydra, you need to find the sequence of attacks which kills it in the least number of wounds. Hydra Slayer also features divisor weapons, blunt weapons to stun heads, missiles, and shields, and a number of other magical items which are unique to this game.
