Unknown to some "Call of Duty: Mobile" players, the Anniversary update also rolled out secret codes that reward players with lots of freebies like weapons, skins, and many others. However, the task involved is not that easy if players do not know what and where to look for. In this guide, players could learn proven tips and tricks on how to unlock all secret codes and earn loads of free rewards.

Before unlocking all the secret codes in "Call of Duty: Mobile," players must first complete hidden objectives found in the new Club section recently rolled out to the game. There are three tasks that players need to complete to obtain three codes.

First Secret Code in "Call of Duty: Mobile"

Players should pick up a glowstick, which could be found in various locations in the Club. After that, go to the Chopper Command poster located on the pillar to the left and whack it with the glowstick several times. The poster would catch fire after a few whacks.

Move to the next poster on the right pilar, this time, it should have 'Pawn' text written on it. Use the glowstick again to whack it to get a pop up with a redeem code. "Call of Duty: Mobile" players who can do this should also receive the same code on their in-game inbox.

Second Secret Code in "Call of Duty: Mobile"

For the second secret code, players should start playing the dart game. Choose to play a practice game and score three consecutive points to unlock a secret code. Some players score double or triple points, but it does not count.

Third Secret Code in "Call of Duty: Mobile"

The third secret code is a little bit trickier than the first and second codes. This time, "Call of Duty: Mobile" players need to deal with people in the Club who will, at this point, try to get in the players' way. Look for a football and use it to knock over four bottles.

These are located at the entrance, in the middle of the bar counter at the foot of the stairs behind the Chopper Command poster, and near the gate to the right of the bar counter. It is crucial that the bottles must be knocked down in this particular order to get the third and final code.
