Many thanks for your response.
Some info of my game:
I'm currently developing a SHMUP for mobile devices and some of the features which i'm thinking of is as follows
1) Players to unlock ships, weapons, colors, effects through attaining certain achievements in game.
2) To support online multiplayer up to 4 players .
The reason why i need a server side data host is to prevent client side hacking to unlock achievements and items without actually playing the game. And also to support online multiplayer.
Are these functions possible with C2? So far i can't find actual documentations on these topics
