In order to complete the game, you will need to do a few things. First, you will need to find the hidden object scenes. These are scattered throughout the game and can be found by looking for objects that have a red cross on them. Once you find them, start looking for other tasks that are associated with each scene. Next, you will need to complete side missions in order to earn rewards. These rewards can include money, weapons, or vehicles. Side missions can be found by searching for specific keywords or by following specific paths. Finally, you will need to play the game in co-operative multiplayer in order to earn rewards and progress through the game. This is done by joining online games and playing through waves of enemies until one team has won all of the challenges.
