Rebel: No Remorse is a total conversion mod for OpenXcom, transforming the classic X-Piratez experience into a unique narrative-driven game. Set in a dystopian future, players join the Global Resistance to overthrow the oppressive World Economic Cartels (W.E.C.), navigating through urban landscapes to collect resources and build their forces. The mod features a compelling storyline, where players must loot and strategize to survive while completing 25 challenging missions.

Gameplay mechanics differ significantly from traditional X-Com titles, emphasizing resource management and tactical combat without the usual starting advantages. Players must carefully manage their soldiers, scientists, and engineers, as losing all will lead to failure. With regular updates and bug fixes, the mod introduces new features such as a revamped Black Market system, unique crafting materials, and expanded mission variety, providing a fresh take on the classic strategy formula.
