Г  A NEW add-on mission for registered Descent  Г
ГллВВВВББББББББАААААААААААААААААААББББББББВВВВллГ
Г             Magnum Three  v 1.0               Г
Г This is the third mission of seven for the    Г
Г Magnum Mines. You stopped them at Magnum Two, Г
Г but they escaped and are back for the hot     Г
Г plate materials at Magnum Three. Hot plates   Г
Г have a devistating potential; the importance  Г 
Г of gaining control of this system is great.   Г
Г Fortunately, the resistance at this outpost   Г
Г has been reported as "light". Of course you   Г
Г never know...                                 Г
Г This level is appropriate for individual,     Г
Г Anarchy, or co-op play. Careful design and    Г
Гfully multiplayer supported and tested.        Г
