I have challenges for anyone who's bored: 1. Build a good Boarding Action remake outside of Blackout. 2. Build a good asymmetrical map on Avalanche that would work with symmetrical gametypes. 3. Make a Cold Storage infection map that doesn't suck. 4. Make a good map with a real looking pyramid not an ugly on made out of double boxes.
I have one that could qualify: Dark Zombies: Gametype Map I posted a thread on FH a long time ago, but it got pushed back so far by now and I'm too lazy to look for it.
