This is the Chaos Knight map that I mentioned on another topic.
My website is being a bit strange at the mo, but I think that link is OK.

Not much gameplay in it. Walk up the bridge and lots of enemies will across come and attack you. You have a few black knights to help you.
Press kb 1/2/3/4 to enable hunter-seeker balls. kb 0 to disable. With the balls enabled you automatically use melee attacks if an enemy is within striking distance. If they are further away a ball is launched and will seek a locked on enemy, or if no lock will seek nearest. The numbers select different damages.
In ball mode you can toggle the range with the 8 key. On long range the ball will go high and 'look' for enemies. Handy for archers on high walls. Press 9 and you select multi-balls. The ball will go so far and split and seek any number of enemies it 'sees'. In this mode the damage is also divided by the number of balls.
Press Backspace to trigger flamethrower. There is a slider on the HUD that displays the fuel level. You can top this up by drinking the fuel cans on the wall to the right.
I've left the .mp with all the compiler files in. The inside of the castle is not in a finished state. Feel free to build bits on and alter it around.

I gave it a quick run though before uploading and everything seemed to work although it did crash after a while. That could just be a graphical thing on my PC.
