I have always been a huge fan of the Random map option, and now that there's a medal for it I am hosting a tournament using my favorite Random map settings.
The tournament will start with 48 people.
Round 1 will be 8, 6-player Terminator games. Each kill is worth 1 point and a win is worth an additional point.
After Round 1, the 8 players who were the first to die in each game will be eliminated. Round 2 will feature 10, 4-player Standard games. A win here is worth 3 points, with 2nd place earning 1 point.
After Round 2, the 8 players with the lowest number of points will be eliminated. The remaining 32 players will be seeded by points into a 1v1 elimination bracket. The first two rounds will be best of 3's, the quarterfinals and semifinals will be best of 5's, and the finals will be a best of 7.
I will resolve ties for eliminations or seeding by flipping a coin or rolling a die. Gotta keep it random.

All players are welcome, but I am going to require any freemiums who make it to the 1v1 stage to dedicate at least 2 slots to this tournament in order to keep things moving.
