Any new account is given a free trial over all Cannons in the game session. You can try out all types of Cannons, discovering their fire power and features in a limited time of gameplay.
The length of a free trial is 4 hours in the game session. If you leave the game session, the time counter will pause.
During the free trial, your account is unlocked with all Cannons, which means you temporarily do not need to own Cannon NFTs. However, you still need to fill your Bullets with FMC.
The length of the free trial is subject to change in future.
