DOOM ALPHA 5

Alpha 5 version of DOOM, here is a data from the archive:

It's an ALPHA version of doom (I just run it to make sure)
called "Doom: Evil Unleashed". Start up screen says Doom Alpha by
Id Software.

It has the basic Doom engine, but
* The imps and pink demons are in the game they don't move or anything
just stand there
* No barrels (as noted above)
* A lot of graphics from wolf is used (eg medic kit, gold treasure cup)
* The map key is "a" not tab
* The strafe and open door key are both alt
* No sounds!
* The two weapons you start with are (1) bayonet and (2) rifle
* There is no run key (that I could find, so makes getting around really
slow)
* It is quite easy to recognize some of the structures in the game
(so the whole map structure is now over two years old). I can't
quote exactly were they are from but I do recognize them
* In the screen options there is high, medium, low, <another one>, and
HIGH RES, so it looks like there use to be a high res mode that was
taken out in the official release.

I other thing I did notice while looking through the doom.exe file is
that there is reference to "E1M10 E1M11 E1M12 E1M13", so it looks like
there was original more than 9 levels per episode

The files included in the archives are
config.lmp 152 3-12-95 12:43
doom.exe 471452 22-05-93 17:49
doom.wad 3522207 22-05-93 18:00
dos4gw.exe 231179 11-11-92 9:01

I know this version is really really old (as per the dates above),
but I am still worried about what could happen if I did post it,
It is now over two years old so who would really care it I did.

--> What does everyone else think?? <--

PLEASE, just follow-up this article in this news group, don't email me
It costs me to send and receive email so I don't want my mail box full

Thanks for posting it (and to Chris for you know what ;-). I had a look
at it too, and noted:

} just stand there

There are 2 Barons of Hell in E1M12. If you shoot a monster with your
rifle, it just disappears, i.e. there are no death frames yet.

} * No barrels (as noted above)

There are barrels in one level but not as we now know them. Like all
things (monsters, treasures, ammo, etc.) they just disappear when shot
with the rifle.

} * The map key is "a" not tab
} * The strafe and open door key are both alt

The 'm' key toggles between normal viewing point and a viewing point at
floor level. You can continue to run around like this, but I presume this
is a preliminary hack at the death players' viewing point.

The '[' and ']' keys increase and decrease the viewing area. Full screen
mode (w/o status bar) is already implemented.

} * The two weapons you start with are (1) bayonet and (2) rifle

There is a chainsaw in one level but it can't be picked up. There's a
shotgun (using a rough version of the pump-action graphics) and a missile
launcher (that uses the shotgun graphics), but you can't shoot anything
with these.

} * There is no run key (that I could find, so makes getting around really
} slow)

I found that the diagonal strafe run makes you run quite fast.

} * It is quite easy to recognise some of the structures in the game
} (so the whole map structure is now over two years old). I can't

See below for a list.

The keys 'q', 'w' and 'e' switch to the first three modes high, medium, low.

Most of the levels made it into the final game:

-run <level> final level
1 not used
2 E2M2
3 E2M3
4 E1M7
5 E3M3
6 MAP10 (DOOM II !)
7 E1M4 (no inverse swastika in the "swastika room" yet ;)
8 E1M2 (rough)
9 E1M6 (rough)
10 E1M3 (partly)
11 E2M7
12 E1M8 (really rough)
13 E2M4
E2M1 crashes too early into the level to recognise it, but I
agree with Alden Bates that it could be E3M7

The engine doesn't allow the player to jump off ledges that are higher than
what the player can climb back on. Thus some parts of the levels can't be
accessed, and there are a lot of moving elevators where different techniques
have been employed later.

The cheat codes don't work, obviously, because these were implemented by
Dave Taylor and he joined id sometime in the second half of 1993, I think.

Every level consists off: ExMy, FLATNAME, POINTS, LINES, SECTORS & THINGS.
FLATNAME lists the floor and ceiling textures, which were of course later
merged into SECTORS. The others are pretty obvious. Structures like SEGS,
BLOCKMAP and NODES were apparently added later to improve performance.

There is something that looks like a "-savepcx" parameter in the .exe, and
messages like "IO_ScreenShot: Couldn't create an LBM" and "Screen saved",
but I haven't found a way to actually produce screen shots. There must be
a way, since the doompix1.exe screen shots are older than this .exe. The
same goes for recording demos, as there are 4 demos included in the .wad.

The frame rate dots (-devparm in the final game) are permanently enabled.
At the start of each level, the four players (all green) are already there,
but of course only one moves.

There are references to "actors" in the .exe, so some terminology from the
Wolfenstein 3D engine was inherited into id's next engine.
