Arctic Combat is free to play, and you just have to pay for small add-ons, but not for the game itself. So, you can pay for different upgrades for your character, but jumping right into the action is completely free.
The mechanics of the game, as mentioned earlier, are very simple: two teams with a similar number of soldiers, a closed but relatively large map, and lots of bullets flying in every direction. Before jumping into battle, however, you will have to choose which team your want to join, and select from an enormous arsenal of weapons, such as pistols, shotguns, machine guns, and even rocket launchers.
As you participate in skirmishes and kill enemies, you will gain experience, with which you can buy different skills that will help you out during your next encounter. These skills can vary from being able to run longer to having a type of grenade radar.
Arctic Combat is one of the most entertaining first-person shooters that you can find today. It perfectly combines elements from Modern Warfare and Counter Strike to create an awfully addictive game. You have been warned.
