Each mission in TBoGT is scored to certain criteria: player damage, accuracy, time, etc. You can improve the score by replaying the missions by selecting them off your phone. This option opens up after you complete the main story for the first time.
Thankfully, you do not have to complete each mission requirement in a single run through. They are accumulative over every run you do. This means you can do a mission as fast as possible and not worry about accuracy, or take your time and get those headshots you need. Once the target has been hit, it will be ticked off and you will be one step closer to 100% on that mission. You will probably unlock at least a couple of criteria for each mission when playing through them during the main story. You can then go back and clear up the rest later.
You can see your stats for each mission in the stat menu. Missions that have 0% completed will not show up in the stats though. In the end of mission summary, NR stands for New Record.
Important Note: a mission score will not count if:
- You use any cheat code during the mission.
- You take a taxi cab during the mission.
- You ''replay'' the mission after a failed attempt.
Please see the trophy guide for a walkthrough of all missions.
