Project Reality

Project Reality features five game modes. Two of the most popular game modes are Advance and Secure (AAS) and Insurgency (INS). AAS involves capturing and holding control points, similar to the Conquest mode of Battlefield 2. In AAS, control points typically must be captured in a certain order with one team attacking, and one team defending. The second most popular game mode, Insurgency, is intended to simulate asymmetrical warfare. The Insurgency game mode involves a conventional forces team searching for and destroying hidden weapon caches while the other team, the insurgents, try to defend them. Moreover, the other game modes are Vehicle Warfare (VW) and Command and Control (CNC). The Vehicle Warfare mode differs by putting full emphasis on heavy vehicles and assets, and restricting the player to one kit role (crewman). The play style for Vehicle Warfare is otherwise identical to the Advance and Secure mode where players must capture objective points in order. Finally, the Command and Control mode removes all control points. The objective instead is focused around player built fortifications and their single Forward Operating Base. Players must build and defend their hidden Forward Operating Base while also searching for the opposing forces' base. The mod also features a co-op mode, where human players may play alongside or against computer controlled players. Co-op can also serve as a single-player mode (with bots standing in for teammates).

In contrast to the original system of Battlefield 2, players may not spawn at their squad leader when they die, but must instead spawn at permanent spawn points such as main bases, or at temporary rally points created by the squad leader. Players may also spawn at Forward Operating Bases which can be constructed if supply crates are delivered to the desired location. When constructed, other fixed defences such as stationary machine guns and various defensive constructs such as barbed wire or foxholes can be placed afterwards with the delivery of additional supplies.

The Insurgency game mode diverts slightly from these rules, limiting the insurgent side to spawn at their weapons caches which they must defend, or they lose the ability to spawn. The opposing team can discover the location of these caches by catching informants for the insurgents, after which an enemy cache will be marked on the conventional forces' map, indicating its position. However, insurgents can still deploy and construct destructible "hideouts" to spawn at, which act in a similar way to the Forward Operating Bases in conventional game modes. The conventional forces are also able to construct their own Forward Operating Bases for forward deployment.

Project Reality features over 15 factions with more in development.
