Sniper: Ghost Warrior 3 is one of the few FPS games that understands how revolvers work. Almost all FPS games depict characters holding the gun in their right hand and placing the moon clip with their left. This is incorrect, since the non-dominant hand lacks the dexterity required/preferred for placing the bullets into the gun. Also, the chamber should to be held in place somehow to prevent it moving.
The reason this is strange is because some people mocked CI Games, claiming they "didn't know how guns work", because one of the game's trailers featured an intact bullet, casing and all, being fired from a sniper rifle. The actual game appears to have a fairly obsessive attention to detail that has of course been mostly ignored, sadly. These scrappy Poles make Ubisoft look like a joke. They took Ubisoft's Far Cry 3 formula and created a game that was better in pretty much every way. Better gunplay, better AI, better level design, better stealth mechanics, better sidequests, better... everything except voice acting and story.
