What is the best way to get more rewards from the troop upgrades in Whiteout Survival?

Coordinate with your alliance for troop upgrade support. Many alliances offer support to members, which can reduce upgrade times and costs.

Use upgrade events to your advantage. These events often double the rewards received from upgrading troops during the event period.

Focus on one type of troop at a time to maximize their effectiveness in battles. This focused approach yields better returns in combat scenarios.
