I’m really proud of my team for topping the scoreboard!
This CTF was done through a 3D Unity game where there are 3 locations for you to explore and find challenges in. There were hiccups with some challenges but generally it was still fine. It would have also been nice if the in-game description texts for challenges were made selectable so that we could copy-and-paste them elsewhere for convenience and organization.

I could have been 5th place but unfortunately I did not officially qualify to be a real participant in this event. Still had a good time though, notwithstanding the fact that there was so much ‘steganography’ and quite a bit of guesswork at certain points :)

Thanks organizers! I enjoyed the Binary Bomb reversing challenges. We got 13th place. Sadly solved less for this one but it was fun trying some RE which I usually avoid. My 9 failed solves were because of Toilet Humor 5.

I appreciate the organizers for putting this CTF together because I enjoyed it a lot. It was at a very appropriate difficulty level for novices. Many thanks to my teammates for helping out. Even though it was only basically 2 active players 🙂, we managed to get 8th place, which I am pretty satisfied with considering our little experience.
🎵 For this CTF I was listening to Kygo - Gone Are The Days ft. James Gillespie!
