Hey, everyone!
Here's a link to the Dreadnought, in all it's glory!
Download it if you dare...A quick tutorial on how to use it:
- Open Zdoom with the Dreadnought wad - you can drag the wad onto the Zdoom icon and it will load automatically.
- From the Options menu, select Gameplay Options.
- Find the "No Monsters" option and change it to "Yes".
- Start a new game, and use the cheat IDCLEV** to warp to a nice, open map, like 12, 13, or 16.
- press the tilde (~) key to bring down the command prompt.
- type "summon dreadnought" without the quotes.
- run for your life

EDIT: Mooload was giving some people trouble, so I re-uploaded it at MegaUpload.
EDIT 2: Made the instructions a little more clear.
