Like dude you need that one BOOM engine to play this.
Get it at HTTP://WWW.TEAMTNT.COM if you don't already have it!
You also need the very recent and upto date game called DoomII.

Title                    : Vengeance: SkyBase Sirius IV
			   You can just call it "Sirius IV"

Discription              : One new level.  A project like this is
                           extremely rare for me.  I usually get involved
                           in projects that have at least 32 levels.
                           In fact, this is only my second one level wad.

                           This level is the start of a possible series that 
			   that follows the Vengeance storyline.  
	                   If it continues, I may use a DoomII version
			   of the Vengeance texture wad.

                           Four of these projects seem
                           like they'll never get finished.

* Story *

After the Kalien's attempts to destroy the two human bases on Praxis
(in thier quest for vengeance) failed, the corrupt aliens found away
to manipulate the interdimensional portals, that they had learned to control,
to allow travel accross the distances of time, and other
dimensions.  It had been ten years since
the Praxis Incident and the war, but the Kaliens still wanted to win the war
they had so miserably lost.  The task was simple, travel through a
time portal and invade the humans in the past.

The year the Kaliens had chosen to go back to was 2091.  Five years before
the Praxis Incident.  This was when mankind was suffering heavy casualties
from the war and at its most vulnerable position.  When they walked through
the portal they were expecting to end up on the Praxis that the humans
occupied.  From there, they'd head to Earth.  But they didn't end up there.
They ended up on SkyBase Sirius IV, a base set up for research, waste management,
and transport.  The base is actually floating in the atmosphere of the gas planet
Sirius IV.  

The Kaliens didn't let this minor set back stop them, and continued as planned.
The kept the monsters from the evil dimension coming in, and they left in a shuttle craft to
head to Earth.  This minor accident was actually an advantage, because
Sirus IV was closer to Earth than Praxis.

There plan for Earth was to open another gateway and send hoards of evil
monsters in to destroy its civilization.  Earth was vulnerable,
for it had lost many of its soldiers in the war, and many were away fighting.  

You're mission: Clean out the base, get to the shuttle bay and launch out of
there to find the other shuttle craft.
