Hyperion Writeup

  • Author : Gynvael Coldwind
  • Language : C/C++
  • Upload : May 9th, 2018
  • Level : I will rate it 8/10
  • Platform : Server: Linux | Client: Windows/Linux etc.
  • Files : hyperion
  • Desc : It’s 2017, so even single-player games require Internet connection.

Just recently I decided that I will take a look and I will solve it finally.
