What you do.
You all should know what a gametype is, well, you can make your own here (fantasy of course)
What you do is add in a name, description, and what it is. Try to make it as detailed as possible.
do it like this:
Name: AI time.
Description: Use the Forge to spawn AI, and fight them in this gametype
Max players: 4
How it works: Using player-made maps only, you use this gametype to spawn AI and fight them. If you get the highest rank (15, shown below) you are reccommended to 343I
There are 15 ranks.
1: Wow, what are you THINKING?!
