Graviteam Tactics: Operation Star

Graviteam Tactics: Operation Star is a remarkably realistic turn-based and real-time operational/tactical hybrid wargame. In this case operational phase is turn based on the map, and tactical is realtime in 3D environment. The game continues the series started by the acclaimed Achtung Panzer: Kharkov 1943.

Features
Features include a flexible AI that chooses the best strategy based on dynamic behavior rather than a script, allowing for high replayability. Real soldier behavior takes into account fatigue and morale, as well as experience levels, which all influence battle effectiveness. Game controls almost completely exclude intrusive micromanagement: most orders can be given to any group of troops.

Additional features include:
 * Detailed recreation of weapons and realistic ballistics: bullets and projectiles have characteristics of their real prototypes and follow accurate trajectories
 * Comprehensive vehicle damage system: engine, suspension, wheels, tracks, weapons, and aiming mechanisms can all be damaged separately, affecting the combat capabilities of the vehicle
 * Destructible environment: nearly everything can be blasted and destroyed, from ground terrain to houses and enemy defenses. All traces of previous battles (corpses, destroyed vehicles, environment destruction) remain on the battlefield throughout whole operation
 * Dynamic day, night and weather effects, all of which affect combat through terrain traversability, battlefield visibility, hidden force capabilities, and more, smoke screens, light and signal flares, etc.
 * Physical modeling system - realistically models different equipment and weapons. Operation of both suspension and various vehicle mechanisms, group weapons manipulations, environment interactions are all modeled
 * Armor penetration diagrams - show visual assessment of at what distance and angle armor will be penetrated by a particular ammunition
 * Military encyclopedia with 3D model viewer and detailed data on all units, describing their historical and in-game characteristics. Also, it features convenient vehicle characteristics comparison
