The gameplay was thought from the beginning to be as free as possible. It doesn't matter in which way you choose the order of missions you want to complete. The idea is that you have to complete them gradually in order to earn money, to be able to buy new weapons and gadgets. Freedom seems to be everywhere in the game. You can choose from the beginning which mission to play, what weapons to buy and what battle tactics to use. Every mission begins in a secret compound from where you can select the weapons and gadgets you can carry in the battle.

The vegetation in every location can be manipulated in your advantage. You can shoot trees in order to make them fall down and block the enemy path. Every leaf and bush will bend while you are touching them. The enemy can locate you based on the movement of the plants, but at the same time you could use this to your advantage. This means you have to learn to use the environment. What really impressed me was the so called First Person Perspective cover system. While in Rainbow Six Vegas when you take cover, the camera changes into a third person view, in Warhound the whole thing goes in first person. While you come out from the cover position to shoot the enemy, time slows down for about three seconds so you got enough time to kill the enemy.
The game uses the same graphical engine as in Call of Juarez but as an enhanced version. The engine can now simulate vegetation, can render large maps and is pumped with new graphical effects.
