As it has been said, the game battles are formed by 2 teams, each of 7 players. One of the main objectives for winning the game is that all the enemy's tanks need to be destroyed. However, if the players decide to capture the bases, there are 2 different modes:
Capture the base: one or multiple tanks (from the same team) need to be in the zone to capture. In this case, a loading bar will appear indicating how much they need to wait inside to capture the base, and win. However, if the tanks inside that area are shot, loosing 'lifepoints', they will also loose points for capturing the base, needing to wait longer.
If there is 2 (or more) tanks from different teams inside the zone to capture, no points will be given to any team, as to obtain those points, only tanks from one team need to be inside that zone.
The main difference with the Classic Mode is that in Supremacy it is likely that there can be up to 5 bases, and instead of winning once one base is captured, those bases provide points to the team who captures them. In this case, the main objectives are to destroy all the enemy tanks or reach 1,000 points. The team who captures more bases can reach 1,000 points easily. Nevertheless, those bases can be "re-captured" any team at any point of the game, providing points to the other team, instead of the team that first captured it.
