Nearly 450 people participated in the CTF this year, a new record for us ! Dragon Sector managed to solve “Wheel of Robots” 3 minutes before the end, placing them right in front of Toastless aka Tasteless. Congratulations to them for their 4th victory in a row, and congratulations to Tasteless and Int3pids for their respective 2nd and 3rd place. The full scoreboard is available on CTFtime.

This year, we had a special challenge in the form of a Unity 3d First Person Shooter game, where you had to cheat in order to access certain zones in order to get a flag. Typical ones where a Fly hack and a speed hack, needed to escape from a basement and run fast enough through a tunnel full of mines. It was really funny to watch people trying to go as slow as possible thinking they wouldn’t trigger them. We will try to do some detailed writeups in the near future.
