This is an overview of some basic concepts in the game. For more comprehensive information, please see the HELP command in-game.

Races
The
complexity of this question can only really be answered by playing
each race yourself. However, here are the basic ideas:
ALIENS- Attack very fast, have acid blood that causes damage to
opponents. Disadvantages are that aliens tend to be quite fragile, and they severly lack ranged weapons.
PREDATORS: Have a very high healing rate and are strong in both melee
and ranged. Preds can become invisible by aquiring a shiftsuit.
MARINES: Synthetics are strong in hand-to-hand combat, have good snipe
power, and very rarely run out of movement even in difficult terrain.
However, synthetics cannot heal because of their non-organic nature;
therefore the only way a synthetic can regain full hitpoints is by
dying Humans can heal between battles, and have lower hitpoints than
synthetics. Humans have the strongest snipe in the game.
Stats and Attributes
To see a detailed character sheet, type score.
To
view only your current stats type attr.
Your
stats determine how well your skills are, IE, if you want to hit
people you need coordination, if you want to dodge you need agility.
-Maximum stats for each attribute is 210.
-The
skills are respectively listed under the attribute they rely upon, you
can view these by typing practice.
Equipment
Each
race has different types of equipment, but it is roughly divided up
into two types, EQ and MEQ. EQ is what you can get for free. Each
race has a location near their recall/"Guild", that houses some
starting equipment for them.
-PREDATORS-> Up from recall in the crate.
-MARINES-> East, then up from recall..
-ALIENS-> In the pool of blood located in your recall room.
MEQ
stores are located throughout the mud. Recently the locations have
changed, so please ask on your race channel for help in locating
stores. When you reach a store, type list to display the store's
inventory.

Experience/Currency
Mission Points (MPs) are used on AvP in place of the Gold and
Experience found on most other MU*s. MPs are used to buy MEQ and to
promote yourself to the next level.
You
receive MPs every time you kill something. The best way to gain MPs
quickly is to kill mobs, not players. You do get MP for killing
players, but it's not as effective as killing mobs. Pkilling is
encouraged/required on AvP so get used to doing it, and also get used
to dying. For now, try to avoid PK battles until your character is
stronger.

Levels
Leveling is not automatic as it is on some MUDs due to the fact that
here on AvP, you must decided whether to level or save your MP to buy
MEQ (usually the latter is the best choice). To level, type promote
and follow the directions given. If you need to see how many MP you
have, type score and read the line that says "You have # mision
points." Make sure you practice your skills each time you level!
-PREDATOR -> One south and a couple west, it's a forest, kill the
castrated yautja and iz'te'ets.
-ALIENS -> There are impregnated humans around your recall area, it's
a big square, you can go two north and then east or west, just
follow. Should be easy enough to figure out.
-MARINES -> South, South, West, South from recall, kill the running
aliens, get their heads and give them to dr. hentir, who is South,
South, East Up, West, West.
Abilities
Abilities are covered in the Abilities section of the AvPmud.com website.
Skills
To
see your skills type practice. Each skill is listed under it's
respective attribute, IE, the skill melee uses your coordination
attribute, healing uses your health attribute and so on. It also
displays your current spare practice points and the maximum that you
can train a skill up to.
To
practice your available skills, type prac {name of skill}. You must do
this in your race's recall location.
Some skills use more than one point to increase, be sure to note the cost before practicing.
To unlearn a skill type unprac {name of skill} this must also be done at your recall.

Guns
First you must get the appropriate ammunition, which is most commonly
smartgun ammo drums (for marines) and energy packs (for preds). Then
type rel.
This
is called Sniping. To do it, you must be wielding a ranged weapon.
Then, type shoot {name of target} <{direction, optional}>. You can hit
targets up to two rooms away with most guns.
Aliens cannot use guns but may have other skills that work in similar ways. Check with your local Queen for details.
Space
The
simplest way to get to space is to use a ship. However, ships are
often not available as they get stuck on various planets when people
die after using them. It is possible to traverse space without a ship
if you have an air source. The best form of this is MEQ, but some
newbie eq also functions as vacuum-safe. For Predators, a rebreather
works. For Marines, a small oxygen tank with mouthpiece. For Aliens,
an upgraded emergency breather.
Various planets and other objects are located throughout space, and
most are at fixed coordinates or in a specific orbit, making them easy
to locate. Here are some coordinates of common planets/ships:
[00-00-00] The Corporate Offices of AvP
[16-04-00] LV-426 (Alien Homeworld)
[02-01-00] Yaut (Predator Homeworld)
[03-01-00] Tierra
[02-04-00] Ceres
[02-16-07] Earth
[19-08-04] Pelure
[11-05-02] Rhikora
[11-05-02] U.S.S Organon (PK Zone)
[10-04-00] Exodus (space station)
[03-07-02] U.S.S Socrates
[06-06-06] Weyland-Yutani
When
a ship is available, enter it and find the bridge or control area.
When you reach the bridge, sit down. Then use the command
drive {direction} to move the ship. To enter planets or other ships
type drive in {name of object}.
Clans
Clans are a place for players, usually higher level players, to have
their own start points with amenities such as teleporters and heal
rooms. They can make the game more fun to play, and are a good place
to make close friends on the MUD.
To
view the current clans on AvP, type clans. To apply to a clan, first
you must meet the reqs for that clan. Most of these are posted on the
Usenet Terminal, or you can ask a member of the clan who is on at the
time. To apply to a clan type apply {number of clan on the clans
list}.
