F.A.D (Fast and Dirty) is a generic, quick, uncomplicated yet realistic game system for modern day and future skirmish wargames (which can scale easily to much larger battles). The system is designed to be easy to learn and play but still allow for deep and strategic game play and is built upon basic military principles such as troop morale, motivation, and experience.
Each player fields a force, ranging from a few squads to a reinforced platoon with support elements, including heavy weapons, artillery and even vehicles.
You can try out the game using troops with basic profiles (and the basic rules) and then move on to trying some of our pre-written "official" units, or delve into our army builder and make some profiles for your own units.
