Questions to develop a Third Person Shooter

Inspired by that popular video game Fortnite, I am making my own Battle Royale named Undertime!

Here are the questions:

• Can you import custom textures to build with?
• How do you create a virtual currency like V-Bucks?
• Can you export the games as apk. or ipk.?
• Can you ban players from playing that game?
• Are you able to create a report system, allowing users to report players, sending their reports to me?

That’s all I had in mind to ask, soon I’ll ask more questions.
Thank you for reading.

Did you make Undertime ?
