This is one of three maps released together by Ultrabug - probably the nicest of them, certainly the biggest, at 3.65MB. And what great "ReadMe" files he provides! I think I ought to quote the main part of the text here: "This is the first Nerf ArenaBlast level that I have made. I chose a castle because the architecture was simple. I didn't have any sort of plan for the level; it was mostly just trial-and-error. For instance, there was originally a passage running around the back of the level connecting the two rooms with the Scattershots, but I decided that it was unnecessary and took it out. Also, when I made the cave I wanted to put a bottomless pit below the bridge, but I didn't have the know-how to do a fancy one, so I decided to do something else. I made a feeble attempt at a sleeping dragon, but it was really lousy. I finally decided on bouncy mushrooms, and that's what's in the finished version. It would also have been cool to have had a dungeon, but by the time I thought of it, the level was already big enough. Maybe another map...
"The botpathing isn't really as good as I'd have liked, but there's not a lot that can be done about it. The worst part is the chandelier. I had to put a lot of pathnodes on it so the bots could find their way around. The problem is, with all those paths stretching around, and because it's so narrow, they try to jump from one spot to the other, usually missing and falling to the floor. I also wasn't able to get them to go up to the "loft" area above the entrance hall except when they appear there. Oh, well.
"The "Tech Zone" was just a stupid little addition I made at the last moment.
"Anyway, enjoy the map."
Well, I have only explored rather than properly played this map, but it certainly is large, and carefully made, with many neat touches, such as a dagger stuck in a table - look carefully, it is a very shiny blade, in fact you may be able to see your face in it! Assuming you have no objections to castles being made from extremely regular purple stone, I think you will have a lot of fun here - so why not invite some Bots to join you?
