Far Cry 2 features a number of inventions and improvements on first person shooters and attempts to bring more realism to the genre. By doing so, it slides down into the uncanny valley where any artificiality stands out as fantastic.

The game was developed by Ubisoft Montreal, the same studio behind Assassin’s Creed, Rainbow Six: Vegas, and Far Cry: Instincts, but shares nothing with its predecessors. No Jack Carver, mutagens or feral powers.

Gameplay in Far Cry 2 is more like Assassin’s Creed than anything. Chose from nine different mercenaries and make your way through an wide open African nation fired up in civil war, doing story missions for different factions or finding side quests and blood diamonds.

The world feels natural and realistic, especially from the player’s perspective. You never leave the first person view, even during cinematics or when driving a vehicle, and you always have a visual representations of your actions.

The mercenary’s hands pick up uncovered diamonds and knock on doors. Lose to much health and you have to pry bullets out of your leg or snap bones back into place. There’s no on-screen radar, just a map and GPS that function as part of the mercenary’s inventory.

This style of gameplay eschews a detailed HUD in favor of immersive elements. Its very detail oriented but it works and brings a high degree of realism to the African world of Far Cry 2.

But however realistic, Far Cry 2 is a flawed picture of reality and enters a sort of uncanny valley where every deviation from expected realism is a glaring error. When the normally inventive enemy AI stops and stands there looking dumb it breaks the illusion even more than in an average video game.

Even devices that make gameplay more convenient — like universal ammo for all assault rifles, fixing a shot up jeep with a few twists of a socket wrench, or the helpful moving icons on the your map — seem out of place.

The writing for Far Cry 2 isn’t bad, but the voice acting is horrible. Most characters sound like robots and their sentences are clipped together. It sounds unnatural and kills the otherwise realistic mood.

This expectation of perfect realism is a problem for games that strive for immersive verisimilitude, and something that future titles which attempt to put fit gameplay elements into the game world will have to overcome. Still Far Cry 2 is a big step in a good direction for FPS games and a worthwhile experience.
