Played with Friendly Maltese Citizens and came first in this ctf. I just spent some time solve merger-2077 since last weekend were work days for me. Learning game hacks from scratch in such a short time is challenging. Glad that we managed to solve it.

I played Seccon Quals with PIG SEKAI this weekend, and we finished 7th. This time, I solved a reverse challenge, xuyao, and surprisingly got the first blood. Here’s my writeup for it.

Learned a lot from this game and other players from Maltese Prison Escapees. But sadly, though I can solve some challenges, other players are so quick that I got zero pts in this game. Guess I need to try harder next time. Here are the writeups for those challenges I solved (or almost solved) in this game.
