Forsaken is a post-viral urban warfare mod for Half-life 2, where players take on the role of a team member of one of three surviving factions. Players can suit up as the tactical but brutally efficient Governors, the resourceful and stealthy Civilian resistance, or the zealous and carnage driven Religious cult.

The objective-based team play is all about the control of territories (maps) and the resources in those territories. At the start of a "war" each faction has a certain amount of resources. They can capture more resources by raiding various capture points on a map.

These resources consist of food and weapons supplies. Every round is a day in Forsaken and each day requires you eat and use up 1 food resource for each member in your faction. You capture more food supplies and steal from other factions in order to keep from starving to death!

Hoarding weapon supplies allows you to save up for bigger guns, upgrades, and other special equipment. Weapon supplies are shared resources and you must work together as a faction to know when and where to use them most effectively.

The winner of the "war" is the faction that controls all the territory on the server, or starves the other factions of their resources. All 3 factions play at once over a series of barren cityscapes, fighting for control of this post-apocalyptic world, and ultimately for survival.
