To install, UNZIP the contents of ROCKET.ZIP into your Doom directory, and type ROCKET.BAT at the command prompt. Then , just run DOOM as usual! REMEMBER: Make backups of your DOOM.EXE and DOOM.WAD files before starting installation, since they will both be altered permanently. DEHACKED.INI may have to be adjusted if your directory is different than C:\DOOM. **This is not a product of ID SOFTWARE, and is not supported by them in any way. ** Have a blast, --Drew H.
