Over 340 levels with ranking system.
Are you knew everything about CS:GO? I Don't think so, in this app 4 levels pack:
- Skins (120 levels)
- Teams (41 levels)
- Maps&Spots (86 levels)
- Players ( 93 levels)
Every 20 levels you will get higher rank to unlock level packs, also you will get coins for correct answers, which you can spent for a hints.
To conclude, i hope you enjoy and good luck :)
