4. DOOM 64 Story

The planetary policy was clear. You could not go near Mars or it's moons.
This was guaranteed by the extreme levels of radiation surrounding the bases.
The Dark corridors and large rooms that held the carcasses of demons sat
motionless, abandoned. The bases locked and sealed.

However, there was some movement. A single Entity that could resurrect the dead, was still living.
Though extremely wounded, the monster was able to bring back the dead demons.
Masked by the extreme radiation, it was able to resurrect the monsters until a
decayed satellite noticed something. The near busted probe sent it's last
transmission to earth. The U.A.C was horrified. Fearing an outbreak,
they sent the bad-ass lone survivor of The DOOM episodes: you.
Your mission is clear. Kill all the demons or they will kill you.

5. Items

take your health past the 100% mark, up to a maximum of 200%

PARTIAL INVISIBILITY
Appearance: A Dark Red Orb with Electricity bolts in the middle.

fire all over the place, and you may dodge into one of the poorly aimed
projectiles

NIGHT VISION GOGGLES
Appearance: A visor with purple lenses.
Effect: It would be an insult to your intelligence if I explained this item.

6. Weapons

CHAINSAW
Power: Depends
Max Ammo: Runs on gas, which apparently doesn't run out...
Ammo Acquired: N/A
Best used on: Zombieman, Shotgun Guy, Imp, Nightmare Imp, Bull Demon, Specter.
First found: Level 1-Staging Area

The chainsaw is a damn good weapon, and is alot better than your fists. The
chainsaw is perfect for ammo conservation and is the weapon of choice against
the bull demons, and is the perfect weapon for specters. Again, you have to get
close, so anything more powerful than a cacodemon should cause you to change
weapons. The chainsaw has been updated from that of the original DOOM games, as
it now has two blades, which cut through enemies extremely fast.


PISTOL
Power: weak
Max Ammo: 400 Bullets
Ammo Acquired: Gun-N/A Clip-10 bullets Box-100 bullets
Best used on: Zombieman
First Found: On you at start of the game.

The pistol is the gun you start the game with, and is therefore weak.
It takes many shots to kill even the weakest enemies and is absolutely
hopeless in the later levels. Once the chain gun is found, you should
forget this weapon even exists.


SHOTGUN
Power: Powerful at close range; weak at long-range
Max Ammo: 100 Shot shells
Ammo acquired: Gun-12 Shells Small box:8 shells Large Box-20 shells
Best used on: Zombie man, Shotgun guy, Imp, Nightmare Imp, Lost Soul
First Found: Level 1-Staging Area

The Shotgun will become the weapon that you will use the most often in
a game. It's has plenty of power to take out the lower enemies in one
shot, and is good against Bull demons and Specters, though I don't
recommend it. Don't use on or against anything more powerful then a Hell
Knight


SUPER SHOTGUN
Power: Very Powerful
Max Ammo: 100 Shells
Ammo Acquired: Same as the Shotgun
Best used on: Demon, Specter, Cacodemon, Hell Knight, Baron of Hell,
Mancubus
First Found: Level 3-Main Engineering

The Super Shotgun is a double-barreled Shotgun that fires both barrels
at a time. This weapon has the power of a rocket at close range, and has
the advantage of not hurting you if you fire too close. However, two barrels
means that 2 Shells are used at a time. Also, it has a slower firing rate. But,
while it may only have two barrels, it does triple the damage of an ordinary
Shotgun blast. Use this against powerful enemies in tight spaces. Another good
tactic with this weapon is that if you are a ways away from a large group of
zombies, firing this weapon will hurt and even kill two or more of them.


CHAINGUN
Power: Each single shot is equal to that of a pistol shot.
Max Ammo: 400 Bullets
Ammo Acquired: Gun-20 Bullets Clip-10 Bullets Box-100 Bullets
Best used on. Groups of Zombie men, Shotgun Guys, Demons, Specters, Lost Souls
First Found: Level 2-The Terraformer

The Chain gun is a pretty decent weapon. While it's shots are only about as
powerful as those of a pistols, it's rapid fire will tear the hide off of about
anything. The chain gun is best suited for groups of enemies, but be careful
with it, as it eats up ammo in a hurry. Another advantage to the chaingun is
that it's constant spray of lead will keep the enemy stunned and it won't be
able to return fire. Be careful, though, as powerful enemies may shrug off the
attack long enough to release an attack.


ROCKET LAUNCHER
Power: Very Powerful
Max ammo: 100 Rockets
Ammo Acquired
Best Used on: Hell Knight, Baron of Hell, Mancubus, Arachnotron, Cyberdemon
Mother Demon
First Found: Level 3-Main Engineering

The Rocket launcher is one of the best weapons in Doom64, or in any Doom for
that matter. While The Super Shotgun has power equal to the Rocket Launcher, it
loses it's power at longer ranges, whereas the Rocket Launcher has the Same
power at all ranges. It also Shoots faster and reloads quicker too. However,
there are some drawbacks. First, if a rocket detonates at a close range, you
will take damage from the blast. Also, ammo is pretty rare, so only use this if
you have to. The gun also "kicks", which means it will scoot you back a little
bit with each shot fired. This gun is the secondary weapon of choice against
the Cyberdemon. You can also eliminate groups of minor enemies with only one or
two rockets. The blast will completely decimate the target, and the explosion
of shrapenal will damage if not kill the others.


PLASMA RIFLE
Power: Moderate
Max Ammo: 600 Energy cells
Ammo Acquired:
Best Used on: Nightmare Imps, Cacodemons, Pain Elemental, Hell Knight
First Found: Level 7-Research Lab

The Plasma rifle is a great gun as it fires high powered shots at quick speeds
and holds quite a bit of ammo. However, the ammo is consumed somewhat quickly
and the energy cells are quite uncommon. Also, the long streams of plasma bolts
may hide an enemies counter-attack. But even with these drawbacks, the rifle is
still a great weapon to have.


BFG9000
Power: Extreme
Max Ammo: 600 Energy cells
Ammo Acquired:
Best Used On: Baron Of Hell, Arachnotron, Cyberdemon, Mother Demon
First Found: Level 10-The Bleeding

The BFG9000 is the most powerful weapon in the Doom arsenal. It puts out
immense power and the shockwave emitted when the blast hits something will
destroy enemies around it. However this gun has many drawbacks. First, It uses
many of the already rare energy cells with each shot, taking 40 per trigger
pull. Also, the weapon takes about 2 seconds to charge up after the trigger is
pulled, leaving you open to counter-attack. And lastly, the power has been
weakened from it's PC counter part, so the shockwave emitted is less powerful.
Use this weapon against the Hearty Barons and the Rocket Launching Cyberdemons.


LASER RIFLE
Power: Depends
Max Ammo: 600 Energy Cells
Ammo Acquired:
Best used on: Depends
First Found: Level 12-Alter of Pain

The Laser Rifle is a new addition to Doom. When the weapon is first picked up,
it is almost useless, as it has the power of a Plasma Rifle, but shoots much
slower. However, in each secret level, there is an artifact. Each time one of
these Artifacts are picked up, the Laser Rifle will be upgraded. If all Three
are aquired, the Laser becomes extremely powerful, as it fires multiple lasers
at a time. The upgraded gun can tear through anything and rivals the power of
the BFG.

1. Buy Doom 64
2. Download it
3. Play doom 64

[Dizzyfatpigeon]

Great guide! But I'm wondering, is there a way to get this to play with the official steam release to log steam hours?

After following the steps I tried to rename the DOOM64.exe to the Kex doom_x64.exe
but then clicking play via steam will immediately verify the game files and then launch the re-release version

I already have Doom64ex installed and ready to play but I keep having trouble with the mouse lag even after the SDL.dll fix. Does anyone know what I should do? I replaced and reinstalled but nothing has fixed it. I know the official doom 64 is hours away but I prefer to play the ex

[Puckfig]

OK, OK, my bad.
I had to replace the SDL.dll with the one that you have to download from just under the main Doom64 EX File on their website. All works now.
Thanks a bunch, man. Appreciate the tutorial and the help.

[Puckfig]

Oh wow, it's coming to PC?! Nice!
I've enabled Mouse look but when I try to turn it's just shaking and forcing back to centre =/

[VolnuttHeroP64]

I may move this guide to DOOM 64, when that game comes out for PC.

[VolnuttHeroP64]

You will need to enable Mouselook from the Options Menu

[Puckfig]

Awesome! I got it. I was being an idiot.
One question: The mouse keeps snapping back to centre and won't turn.
Is that to do with "DOS Controls" like you said, if so, how do I change those?

[Puckfig]

Man, thanks for getting back to me so quick.
I deleted my comment as you responded because I think I've got it.
