Shields Up! is a quick 18 card game that plays in under 20 minutes. I created this game as an entry into The Game Crafters Hook Box Challenge. Basically the challenge was to create a mini 18 card game that fits into a hook box. After several months of play testing I settled in on my entry. Being a small and fast game it was easy to get people to try it out and even easier to try many variations. I am really pleased with the resulting balance. I look forward to seeing how the contest goes.
