You start off as a prisoner, and you have to escape from your confinement. The quest to destroy true evil begins tonight. Our only hope for salvation is you, the Knights Templar, a tactical, holy warrior who serves the cross. The portal to hell has opened to earth's realm. This lets you get familiar with the weapons and movement of the game in a virtual environment. This one is a pretty neat addition to the game. From the HQ you have the ability to take on new missions, buy weapons, hire new recruits and so on. You play as a mercenary, operating out of an HQ for, you guessed it, mercenaries. This is a very well-made, user-created campaign. Well, hold on to your butt, because I have compiled a slamming list of beautiful additions to your Arma 3 library that is sure to keep you occupied for hours and hours.
