Rushaug: Feline Warfare
A downloadable game for Windows

Rushaug: Feline Warfare (formerly known as Project Emerald) is a polished single-player experience with tons of guns, espionage, military jargon, and enormous replayability.





The world is torn apart by ideology, ultra-nationalism, and cat breed-racialism.
In the midst of this instability, collective powers are trying to insert their influence through force. Global Alliance Treaty Organization (GATO), a joint military force, is fighting to defend independent nations from being grasped by the mighty Dekenzian Manifesto Allegiance (DMA).
Rushaug–an elite soldier operating behind enemy lines–is gathering critical information, all while sabotaging the enemy from the inside. His accomplishments do not go unnoticed, and he is quickly building a reputation as a formidable opponent. The DMA is determined to stop the threat, prompting General Zargasso to dispatch special forces to hunt down and eliminate Rushaug.
Unknowingly, Rushaug is about to meet his equal; Red Nuke.

Play Mission 1: Operation Arctic Strike for free!
Enemy has deployed a new fleet of nuclear submarines to remain hidden under the glaciers of the arctic. Undetectable, and armed with hypersonic missiles, these submarines ensure nuclear deterrence.
Suspicious missile testing suggests enemy is training for engagements. We are tasked with investigating.

- EXPLORE a range of locations — everything from the freezing arctic, an unforgiving desert, a deep and claustrophobic bunker hidden in the woods, a Guerrilla-occupied old rum distillery on an island paradise, and even venture into space to another planet!
- INFILTRATE hostile settlements ranging from remote outposts to top-secret military bases. Use stealth to your advantage, or go guns blazing with the heaviest hardware you can get your paws on.
- ENGAGE in combat against enemies such as the skilled infantry of the DMA, experienced guerrilla fighters in Catvador, or take on the feared Bolse Death Squadron. The game puts huge emphasis on gunplay, and realistic bullet velocity, so it is all about quick reactions.
- COLLECT intel to reveal intriguing information about the characters and events within the world, and find gun schematics to unlock 40+ different weapons to choose from.
- UNCOVER the true purpose of Project Emerald and save the feline world from societal collapse and nuclear armageddon.
