Details

Overview

Combined Arms Operations Series (CAOS) plunges players into the heart of operational-level World War II combat, offering a unique simulation experience where turns unfold simultaneously. This isn't just about reliving history; it's about reshaping it. Imagine pitting Soviet and US forces against each other in 1945, or pitting Germany in 1939 against Italy in 1942. CAOS provides the sandbox for these 'what-if' scenarios.

Highlights

Simultaneous Turn System: Experience operational combat where all players issue orders at the same time, leading to dynamic and unpredictable engagements.
Alternate History Scenarios: Explore 'what-if' possibilities by mixing and matching historical armies and units across different years and national boundaries.
Deep Simulation: Follow historical doctrines or forge your own by reorganizing armies to suit your command style, from massing artillery to creating elite combined arms kampfgruppes.

Who It's For

This game is designed for strategy enthusiasts and history buffs who enjoy deep simulation and the intellectual challenge of operational-level wargaming. If you've ever pondered how historical conflicts might have unfolded differently with altered forces or strategies, CAOS offers a compelling platform to test those theories.
