I've had nothing else going on in my life for a few weeks. Literally nothing else, I've been at home all day every day doing two main things:
1) learning UnrealScript so I could write a mutator that lets me record (in a config file) ideal player counts for individual maps, so that whenever I start a match the mutator automatically sets the number of bots based on the data in the config file, and
2) learning UnrealEd while making my first map. I was hoping to be finished by the time my job starts (tomorrow, Jan. 18) but I didn't quite make it all the way. But I'm so close, and I will still have some free time to work on this map, despite my job. I'm almost ready to release a "beta" version of the map, and I will in a few days once I deal with the most obvious problems. But for now, I've attached some screenshots to this post.
The map is tentatively called DM-Substrate. I haven't checked if someone's already made a map with this name.
