This game's developer is super generous! They really give so much gems and banner pulls every update. The game's theme is very cute too! School girls with weapons!. The gameplay is very nice and you need to strategize in order to win. However, this game QoL is INSANE. You can complete daily very fast due to the skip system. The story and music are also very good. Try it yourself!

1. Total Assault (Raid), rotates every 2 week
2. Joint Firing Drill, rotates every 2 week
3. Tactical Challenge (PVP)
4. Bounty and Comissions
