AAS (Advance And Secure) is a gamemode in Project Reality which consists of several capture zones or flags placed around the map. Each team starts with a similar amount of tickets, and the team that loses all of their tickets first loses the game. Tickets are reduced by wounding and killing enemy soldiers, destroying vehicles and capturing enemy flags.
The main objective of AAS is to secure areas around the map in a specific sequence.
To win an AAS game, one side must cause the enemy's team to reach 0. To do so, players can either capture flags away from the enemy, which causes 30 tickets to be lost by the enemy each time a flag is neutralized and captured. When a team is down to their last flag, or has their last flag captured, they will begin to lose tickets over time, which is commonly called "ticket bleed". Once the last flag is captured, a team cannot spawn anymore, and must wait for the remaining forces to retake the flag, or wait until the match is over.
