Well... you really should read the manual if you would like to have some understanding and control over the game. But, if your house or cat are on fire, then first: I didn't do it, and second:

• In order to play, you have to set up at least 2 players. So, go to the Setup Players section using the up/down arrows, and press enter.
  Press enter again, to create a new player. Enter the new player's name. Repeat.
  When done adding players, get back to main menu by hitting escape.
  
• Next, go to Assign Players (Highlight it and press enter). Here, select a player, press enter, and then choose what controller device this player will use. Press enter again to go back to player selection.
  When all desired players have their controls assigned, press escape to return to the main menu.
  
• You might want to check out the game's keys... Do so at the Controls menu.
• Head over to Start. The Word DeathMatch is highlighted. Press enter again to start playing.
  To terminate the game before it's completion, press escape. To exit the game, press escape twice (first escape goes to main menu, second one quits).

No probs. First thing is a genreal description.

Space 82 3D combines the ship controlling method of games such as StarControl or Astroids, with the viewpoint of Doom. Additional game concepts were added, such as different game modes - DeathMatch, Hold the flag, and racing. Up to 4 players may play at the same time, on the same computer. Players may demolish eachother using 8 different weapons. An inline track editor is available too.

OK, now that we are over that...

Space
Unfortunately, 4 ships on an infinite space is quite a thin idea. The space in Space 82 3D is round. When you are approaching the edges of the space you are being warned by a blinking "Outer Belt" warning on your viewport.
If you exit the valid space, you are automatically fragged.

Pickups
Pickups are your resources. Running over a pickup will add ammo to one of your weapons, install you the shield damager, or restore some of your armor.
In DeathMatch or Hold the Flag, pickups are those rotating blue crystals circles. Grab them by running them over. On Race mode, you get your pickups when you pass through checkpoints.

Weapons
What we all been waiting for...
All weapons cause a certain shock to the ship while firing. That shock effects only the weaponary system. Once the system has recovered, you may fire again. A bar saying "READY" fills up as the system recovers. When the READY bar is full, your system is ready to fire again.

• Missile Launcher
  Launches a homing missile. Missile does about 33% damage. The catch is, you have to keep the target inside your crosshair for a whole second, until it turns red. Only then you may fire. Attempting to fire before the lock is gained will reset the locking device, therefore taking more time to lock. Reload time is quite short.
• Magnetic Mines Dropper
  Drops a mine. This is no ordinary mine. Two seconds after it was dropped, the mine creates a gravitational field, pulling players towards it. 5 seconds later it explodes. It's very hard getting away from it once it pulled you in.
• Pulsoid
  Hold the fire key to charge it. Once the charging bar has passed the red part, you can let go. A radial blue pulse is then emitted all all around you. This will also happen when you cannot charge anymore. Damage varies according to how long it took the pulse to go through the ship. Can kill in one shot.
• Riot Starter
  One of the more powerful weapons around. Firing ejects a sea-mine looking projectile which advances forward. Then it splits up to 5 smaller parts, which spread out, and then each of them split up to even smaller parts that spread out. Those parts fly a bit and then pop. Any part, including the first one, that hits a ship, sticks to it. If you dunk the first one, you've got yourself a sure frag.
• Sniper Gun
  This is the only long-long range weapon. Hold the fire key to zoom in, let go to fire. The farther the bullet go, the greater the damage it makes. Can frag in one shot from a far distance. Bullet is faster than the eye, it hits exactly where you aim when you let go. The gun's range is limited however, but is really long. The engine is turned off when you are zoomed in, so you can't move, only rotate.
• Sprinkler
  A machine gun. With one twist. It doesn't fire straight... It spreads the bullets like a garden water sprinkler, from side to side. Very rapid fire, not much damage per bullet.
• AfterBurner
  It's abilities as a weapon are puny, since it produces purple engine products backward, which fade very quickly. It's main function is doubling your maximum speed. Each engine waste hit reduces 25% of your armor.
• DoomsDay Device
  Kaboom. Sets a device that goes off in 1.6 seconds. A huge multi-leveled implosion sweeps off anyone in it's range. There is no way of surviving it if you are anyway near it. This especially goes to the one who placed the device, he always pops. If you are too far to get into the implosion, you are probably tossed away from the power of the blasts. I suggest you resist this, or you will exit the valid space. In order to gain something out of this one, you need at least two enemies within range.
• Shield Damager
  Not a firing/deploying weapon, but since it's sole purpose is damaging other players, I list it here. Picking this one up installs the shield damager until you are fragged. The shield damager reduces enemy players' armor by bumping into them. Each time you bump into someone, it takes 30% percents off his armor. If your shield damager is installed, you will see a yellow ellipse with the word ON in it, next to your armor bar.

Frags
When a player's armor is zero, he is fragged. The player who brought him to zero is the fragger. Every frag you make, your frag count rises by one. If you frag yourself, with a weapon or by wondering off valid space, your frag count is decreased by one. Frags only really matter on the deathmatch, where they are the objective. In hold the flag and racing mode, frags are the means, not the cause.

AfterMath Screen
At the end of a game, comes the aftermath screen. Each game mode has it's own aftermath screen. The titles on the left is the "who", the titles on top and the "to who". Ummm... that's not very clear... so here's a little chart:

_____|_____X_____|_____Y_____|_____Z_____|____Evryone____
  X  | X frags X | X frags Y | X frags Z | X total frags
