* Further description and gameplay notes *
* Background * This is a level I did for a friend as part of our
personal TC. He specifically requested a level where
he "could do lots of sniping, hide behind stuff and
fight enemies in depth positions where the enemies
do not chase you all over the level". Well, he got
what he wanted. As to whether this type of gameplay
suits anyone else - who knows?
The level has been taken almost directly from the TC
but has been "Doomified". i.e. the TC weapons (bar
one) are not present and the whole thing has been set up
slightly differently. I thought about making it like a
"Marine Assault 2" because the weapons and feel are
similar, but I wanted try and convert some of the TC
enemies to DECORATE rather than their original dehacked.
The enemies are "Incas" or "Incanese". These are from the
A personal Role playing scenario. In the year 2386, the
Inca Free Republic attacked Britain without warning, against
all treaties and breaking many years of peace on planet
Earth. The IFR is far from free, however, they are a
fascist dictatorship with unworldly connections to
None of that should be taken to infer any prejudice against
present day South American countries. It's just a story -
nothing to do with the real world.
Of course this is all irrelevant to "Operation Overlord"
because I have made it for a UAC marine rather than the a
British Galactic Police Association (BGPA) officer from
the original TC.
Why did I go for the Incas rather than making it a more
obvious WWII German mod? I had the Inca sprites already,
the level was set up for them, I wanted to use modern/
futuristic weapons and why not? That's how the original was
* Running * :As usual, Unzip the files into and run with the -file parameter.
However, for the first section of the level I HIGHLY recommend
setting up an alias to zoom in on targets as a lot of the enemies
are far away and you are provided with a railgun to snipe at them.
If you want to use my alias, I have included a file "njol.cfg" you can
start the game using
gzdoom +exec njol.cfg
(or use the batch file if you have unzipped into your GZdoom directory)
This will automatically load the WAD and set up a zooming
alias. If you do this, you should hit the X button in game to set
your preferred crosshair (I have included a few new ones). If you
do not do this, your crosshair will get messed up when you zoom in.
Once that is done, you will then be able to hit "Insert", "Home" and
"PgUp" to toggle 2x, 5x and 12x zooming. the "End" button resets to
normal view. These buttons can be re-configured via the menu.
* Gameplay Notes * :Crouching and Jumping in this level are not only allowed, they
are highly recommended, if not essential.
This is not intended to be a typical Doom level. You are supposed to
sneak up the beach using the cover provided whilst sniping at the
enemies. If that isn't to your taste, you probably won't like this
mod. It wasn't made for you anyway. :P
Seriously, just running in and blasting away will get you killed.
* The sections * :There are kind-of 3 sections to the level: the initial beach assault,
the trenches and towers and the final bunker complex.
The beach area is the area where you will have to go cautiously. Use
the beach defences to hide from enemy fire, pop out, snap off a
shot and get back in cover.
Once you clear the beach, there is a quick dash across a minefield
which is covered by heavy machine-gun fire. You can shoot the
machine gunners but it won't be long before they get reinforced.
Once you have passed the minefield (the music will change) the
machine gunners will no longer get reinforced and you can go back
and kill them permanently if you want.
The trenches and towers are more traditional Doom gameplay in style
but you will still need to keep your wits about you because there are
lots of machine gunners in defended alcoves. At the top of each tower
is a key. You can go into the towers in any order you wish.
The bunker complex is a repetitive room to room clearing operation.
You may or may not enjoy it, but it's exactly what my friend asked
for, so he got it.
* Special Equipment * :In overlord, you can find 2 inventory items: Grenades and Portable
Grenades come as single pick-ups or in boxes of 5. Some enemies also
drop them. To use, ready them in the inventory and hit enter. Grenades
(except the ones dropped by enemies) can always be picked up but the
maximum inventory amount is 25. If you are carrying 25, do not pick
any up until you have used some otherwise the pickup will be wasted.
Portable Health Packs are identifiable by the green cross on them. In
stead of being used instantly, they get added to your inventory and will
give you up to 25% health back as and when you choose to use it.
* New Weapons * The BFG has been changed to a rail gun. This allows the sniping which is
quite important for this level and the old BFG behaviour is not so useful.
A DECORATE Thompson has been added. It's really an Easter Egg as much as
anything else. Clearly this level is inspired by WWII games like
MoHAA so it was a bit of fun to add a Thompson. It's no shabby weapon
though and is probably a slightly more powerful weapon than the chaingun.
