Dont download anything then. A lot of the offers just require you to take a survey or become a fan on facebook or something along those lines. So far, i got points for watching a microsoft advertisement, taking a few surveys, and playing a couple facebook games.
if you dont want to try it, then you dont have to, i just made this thread because a few people asked me how to get free war coins and they wanted screen shots.
this thread is purely for educational purposes and i do not gain anything personally from it. However, vortex wars is paid through this so you will be supporting the game as well as getting upgrades that will help you in game.
