"Thy PrBoom Maps" by Mrthejoshmon

Intro: The planet "Centurian-D8" has been colonised for hundreds
of years now, the planet is a very Earth like exoplanet that
houses every requirement for life to thrive on its surface.

You have been deployed to this planet after a violent attack
on the surface of the instillation. You arrive to find entire
cities in ruin, this is no firebase raid, this is a full blown
invasion...

Maps and info:

MAP01: WTP (Water Treatment Plant)

I am heavily inspired by TNT Evilution and many 90's wads,
This map has some structures that are shaped like areas from
Final Doom TNT, this is because I love TNT Evilution so much.
This map WAS a vanilla map, of course I messed it up, so it
was moved up to PrBoom format.

This map was featured in the megawad: "NOVA: The Birth" 
It was MAP03.

The difficulty of this map is extremely low, should be a quick
and easy run.

Story: The WTP is just a front for another lab, what goes on back
there is a secret... Until these things invaded, looks like you
will be finding out shortly.

MAP02: Incubator

This map was my first tec base map, and I gotta say I am very
glad I kept this map rather than give up on it. This is one
of the very first maps I ever made and I am surprised it got
positive feedback at all! This map went through about 5
versions before the final version.

This map was featured in the megawad: "NOVA: The Birth"
It was MAP12.

Story: So the UAC were trying to preserve plants, that is a
huge surprise as you were expecting some sort of horrible
human testing lab or bio-weapons division. Lucky for you
though there happens to be a lot of demon interest in plants.

MAP03: Compound

This was one of the only really "Good" maps I ever made, and
you will most likely hate it. I chose the music here from Duke
3D as it conveys the dark and gloomy nature of this storage relic.

This map was featured in the megawad: "NOVA: The Birth"
It was MAP08 I believe.

Story: After pulling out of the now bloodstained incubation lab,
you now find yourself at an old, gloomy and forbidden compound.
it also looks like your "friends" have set up shop here as well,
there is an old sewer substation you can use to get the hell outa
here and it just happens to be on the other side of this brick
house of horrors.

MAP04: Sewers

I hate sewer maps, this one was extremely short to begin with, I
then went back to it and expanded it longer. Not much to say other
than I made the really annoying music for this map. you are welcome.

Story: This is one hell of a trip huh? You were able to get out of
the damp compound into the wet and dirty sewers...
Oh well, look on the bright side: There will be plenty to kill down
here, so load your weapon and get to it!

MAP05: Site

Odd map this one, began as a tech base, turned into a cave, then a
tech base again and then both. This map was a pain in the ass to
make due to design changes but just remember: It was much worse
than this at one point.

Story: The teleport in the sewer left you in this old outpost,
these locations get more and more distant as you go on. This
place links to an old channel of water that you could use to get
back into the industrial area to rescue the remaining lives on
this horrible planet, take warning though, the enemy know you are
here.

MAP06: Rip and Tear

This map began as a chainsaw/fist only map that sucked really bad.
I had to remake this level from scratch it was that bad, I changed
the map into a more action packed battle in an old water collection
and storage area.

Story: This is perfect, after jumping through the nearby hole in the
roof your fate is now sealed. You must carve your way through this
heavy enemy resistance to get to the next area of this concrete jungle.
Heavy resistance? No problem... Right?

MAP07: Cyberden

This is a dead simple like map involving a cyberdemon on top of a blue
key, you must kill said cyberdemon to get the key. Simple.

Story: Looks like the enemy have a commander up next in line for your
body count, he could have chose a much nicer place than this air cargo
point.

MAP08: Lockdown

I think this is one of my best maps, I spent ages on the overall layout
and optional areas included in this map. i hope you enjoy this map as
much as I did making it!

Story: A military complex stands between you and your ride out of here.
This is a derelict ship passing by this sector, if you can get through
this orthogonal outpost then you can capture the ghost vessel and make
your trip to the freedom of mankind all that bit faster.

MAP09: Derelict

This map has a very odd past, it began as an extremely short map and
then became a very long and boring map, So I cut 1/4 off of the long
version and it seemed to be ok from there on.

Story: You got on this ghost ship, but it turns out that not all of
the crew are dead... Yet.
It is up to you to capture this vessel and use it to reach your goal
of the rescue of all the colonists and captured military personel...
And you are gonna look good doing it to.

MAP10: The Divide

This is one of the worst maps in the megawad, I ran out of ideas for
gameplay ideas and areas so I just threw some shit at the wall until
it stuck, and stick it did.

Story: This is it, this is the location...
Well sort of, the actual point of interest is under this power sation
and in the stations old coal mine, it looks as though the place was
shut down a while ago though. It may be shut down but the main station
thrives with life, please change that fact.

MAP11: The Mines

This map had to be changed completely! The original map sucked so bad
I couldn't even go through the testing process with it! I completely
replace the map with a new one. This new map is much better than the
previous monstrocity.

Story: This coal mine holds the key to saving the captured humans.
It looks like wormholes to hell itself transformed the surrounding
area into some kind of temple, either that or the demons were here
for much longer than you think. You need to enter one of the demon
invasion teleports, go to hell and then free the population.
Should be a piece of cake for somebody of your skill.

MAP12: The Mansion

This map is the first city theme map I have ever made, it is also
one of the better maps in this megawad. This map has many little
secrets and hidden areas for you to find. Happy hunting.

Story: You did it, now it's time to turn the tables!
The main demon invasion portal is located within the largest city
on the planet and you just happen to be the best man on this god
forsaken rock! You are going to have to cut through this mansion to
make progress on reaching the hell portal, good luck!

MAP13: EWTP (East Water Treatment Plant)

This is where I decided to try and ramp up the difficulty a bit.
More monsters and more carnage, whats not to love?

Story: The EWTP, this one isnt linked to some kind of tree farm
however, this place is an actual WTP and is very important to the
demonic horde as they can use it to poison the cities water supply.
You are going to stop them, then you will have to take the elevator
down to ground level and head to the old fort, you will need to run
through there to bypass an entire section of the city.

MAP14: Fortification

This took days to make, months even. The difficulty peaks at this
point, those demons don't want to give up the little fort I guess.

Story: This fort is being heavily defended, it cuts off one half
of the city from the other and is of key importance to both you and
the invading force. You must gun your way through the hostile army
and use the forts anchient elevator to get to the destroyed streets
below.

MAP15: Decimated Streets

This took even longer than Fortification to make, I decided to make
a much harder level for this map slot so prepare to die.

Story: The forces of hell have taken to the streets, rubble and
empty tombstone buildings are all that await you...
Better get to it.
