‘Tank Warfare’ is a shooting action game where you can enjoy chewy tank battles with real-time users. Tanks are divided into regular tanks and rare tanks, and try to level up your tanks by opening the treasure chests you receive only when you win PVP battles and acquiring cards. You can enjoy robot battles while waiting for real-time matching, but please note that it does not affect user level and stats, and gold, points, and boxes are not awarded. You can check the acquired treasure chests in the treasure chest menu, and you can keep up to 4 of them. If you acquire a box again while the 4 boxes are full, you have to consume gold and open or throw away the box right away. Treasure chests purchased at the store can be opened immediately, so rest assured.
