Know Contract war game better
Contract War Hack is a free to play multiplayer browser based first person shooter developed by Absolutsoft with the Unity Game Engine. Contract Wars is currently available for play through VK (social network), Kongregate, Facebook, my.mail.ru, and ok.ru.
Contracts Wars combines FPS and RPG game elements. One example of this can be seen when players level up as they complete contracts to earn credits and gold points which in turn allows them to purchase new weapons and skills.
