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