<td><font size=2>Most first-person games encourage everyone to run
around like madman, ignoring their teammates and being as aggressive
as possible. This will not work for the marines. This means encouraging
the marines to act like a real </font><font size=2>squad. The
resource model is such that the marines must move forward methodically,
in a group fashion to take action before the aliens gain too much
power. Communication is a big part of this, as is tension. Some
of the gameplay mechanics that actively promote this include:
varying resources depending how well a player is doing his &quot;job&quot;
as a leader or green marine, the commander having morale gameplay
effects on his squadmates, the marines don't respawn and automatic
overwatch. </font></td>

more powerful than an individual marine and the alien side doesn't
rely on teamplay to gain power. The aliens are for individual

<td><font size=2>This is acheived through professional orchestral
music and sound effects. Also, by keeping the game mechanics simple
enough to have time to add lots of little details like mist from
the aliens' mouths, and the echo of a rifle reloading in a ventilation
shaft. The shared part means concentrating on players' shared
experiences, like riding massive elevators together, watching
in awe as an alien rises up out of the water, waiting anxiously
as the loading bay door closes and advancing through the ship
as a team. Further immerse the players by encouraging true role-playing.
The awesomely powerful aliens can scuttle and scream to frighten
the marine players and even themselves. The humans should constantly
try to keep their cool and stay organized. They wig out when sarge
dies and run like a little girl when they see a lumbering beast
coming towards them. Everyone has fun playing the role they're
supposed to, and the <i>game rules encourage</i> it.</font></td>

<p><b><font size="2">Morale and resource model for humans</font></b></p>
<p><font size="2">The resource system is modelled through likelihood of resources
getting put to good use. If a player has shown his competence, he continues
to receive resources. If a player fails at his role, he is given less resources
because he has shown that he is less likely to put them to good use. This system
is justified in the backstory but also promotes teamwork and protecting of teammates.
The more players under a player's command, the more his resources depend on
their livelihood. With this greater responsibility should come a bigger reward:
knowledge that a successful mission was in large part to his own efforts and
leadership? An extra sub-menu with special commands? Special priviledged upgrades?
</font></p>
<p><font size="2">Every x seconds, a resource injection is administered. The maximum
size of the injection is determined by a starting number, then increased by
number of aliens killed. The resources a player receives at regular intervals
is proportional to percentage of those below a player in the chain of command
(if any) that are alive. This proportion is multiplied with the current maximum
resource injection to determine the actual injection. Whenever a squad leader
receives resources, the players under his command who AREN'T squad leaders also
receive it. Example: Player A is squad leader for Player B and Player C. Player
B and Player C are at the bottom of the totem pole and command no one. Player
A receives 100% of the resource injection at regular intervals. When he receives
it, B and C also get it so everyone gets one 100% of the maximum resource injection.
Player B then dies. Player A now only gets 50% of the resource injection, which
also goes to C. Another example: Player 1 is the ultimate commander. He commands
Player 2, who in turn commands Player 3 and Player 4. It is time to give a resource
injection. Player 2 is alive, so Player 1 gets 100% of his resources. Player
2 is below Player 1 but is a squad leader, so gets no runoff. Player 3 and Player
4 are alive, so Player 2 then gets 100% of the resources. Player 3 and Player
4 aren't leaders, so they also get the resources that Player 2 got. Now Player
3 dies and it's time to give resources again. Player 1 gets 100% of his injection
because Player 2 is alive. Player 2 only gets 50% of his injection because Player
3 died. Player 4 also gets the 50%.</font></p>
<p><font size="2">The morale level of a player is proportional to the percentage
of players above you in the chain of command (if any) and below you in the chain
of command (if any) that are alive and in a defined range. If there were never
any players below a player in the chain of command, the number of players in
the same squad count instead (those commanded and not other leaders for squad
leaders, and close teammates for lowest-level soldiers). If a relevant player
is alive but not in range, only 50% of that player's morale bonus is contributed.
The morale level for a player is expressed as a percentage and is displayed
at all times. Morale gives a player a defensive bonus and an accuracy bonus.</font></p>
<p><font size="2">This system promotes proximity between squads and makes it in
a player's best interest to keep his commander and fellow squad mates alive.
It also forces the marines to move forward to and kill aliens. It also keeps
the aliens from acting stupid and throwing themselves into the marines' weaponry,
lest they feed the fire.</font></p>
<p><font size="2">How to make the commander a leader? When the leader is more
skilled than the others, it should be evident. Those below him will want to
be led and want to feel like they are under the care and guidance of a true
protector. How to make the commander a leader and not just another player? He
has to have the ability to make decisions that no one else can make, because
they don't have as much information. The commander can be in contact with the
mothership which has more information about this engagement than he does. Maybe
he receives intel about types and numbers of aliens in the vicinity? Informs
him when aliens purchase key upgrades? Let him use his &quot;insight&quot; to
get glimpses of aliens through walls (or at least vague shape indicating amount
and position)? What can we do to make squad leaders feel more responsible and
empowered?</font></p>
<p><font size="2"><b>The alien resource model</b></font></p>
<p><font size="2">The aliens have a constantly increasing maximum resource injection.
It also increases when they kill marines. They have no morale model or chain
of command. The total resources is divided among the number of players on the
team (including dead players). If a player leaves the game, that player's remaining
resources are divided to everyone else on the team. After an alien player dies,
he is presented with a graphical menu that shows all the different aliens he
can respawn back as. One or more of the alien choices may not be available in
the beginning of the match. There should be a choice in the beginning of the
game, not only one alien to select. Alternatively, the player can wait a bit
and receive resources before entering. While this menu is up, they can still
receive chat messages but are at a dark screen (or inside the alien hive mind?).
They can't see the current game in progress.</font></p>

<P>Feature descriptions</P>
</FONT></B>
<P><font size="2"><b>Alien movement: -</b> Creeping, scuttling and flying</font></P>
<p><font size="2"><b>Buying menu -</b> Marines can buy new equipment, armor and
upgrades during the game. The menu is brought by hitting a key. The menu shows
the list of items and upgrades and their prices, also showing the amount of
points each costs. Any upgrade that is too expensive is drawn in red, any upgrade
that is already purchased is drawn in green. The rest are drawn in white. Any
equipment or upgrades that are &quot;purchased&quot; are acquired immediately.</font></p>
<p><font size=2> </font><font size="2"> </font><font size="2"><b>Commander </b>
- Marines within a certain range of the (a) commander has their fatigue reduced
quickly or is completely immune to effects of fatigue. The commander has more
responsibility for all his teammates, so his resource level depends on their
livelihood. With this increased responsibility, does he get any extra power?
To prevent cheating and make the commander role a social distinction, no extra
power would be granted. To compensate for this extra responsibility, the commander
should get something...maybe he just has an booming and authoritative voice
that is distinct from the others. Likewise, the squad leaders should have a
distinct voice, and the grunts their own as well.</font></p>
<p><font size="2"><b>Comm radios -</b> When marines use their communicators (team
chat), they make muffled chatting noises that the aliens can hear. Besides team
chat, marines also have a handful of common sayings.</font></p>
<p><font size="2"><b>Door welding</b> Marines with welding torch can spend twenty
seconds to weld doors shut. Aliens cannot get through closed doors</font></p>
<p><font size="2"><b>Explosive grenades-</b> This is the marines' main form of
indirect fire and is a principal advantage over the aliens. It can be bounced
around corners and does damage to marines as well.</font></p>
<p><font size="2"><b>Fatigue (marines only) </b> When a marine runs <b>or fighting</b>,
his fatigue level increases. When he is walking, it stays the same and when
he is stationary, it decreases. The higher the fatigue level, the slower his
movement rate. He will also take slightly more damage from attacks and will
take longer to arm his weapon. When a marine is fully fatigued, he cannot fire
and his movement rate drops severely. It is important that firing isn't allowed
because the machine gun has unlimited ammo. Alternatively, force reloading.
The fatigue rules promote planning and &quot;leap-frogging&quot; with teammates
and further discourage the one-man army.</font></p>
<div align="center"></div>
<p><font size="2"><b>Flame thrower-</b> </font></p>
<p><font size="2"><b>Gestures -</b> </font></p>
<p><font size="2"><b>Machine gun-</b> Unlimited ammo. Can be upgraded in ROF and
damage. Promotes cover fire.</font></p>
<p><font size="2"><b>Marine movement-</b></font></p>
<p><font size="2"><b>Overwatch</b> - Kicks in automatically when weapon is held
stationary for a few seconds. Marines stay in overwatch as long as they dont
move, turn, change weapons or gesture. Overwatch increases the amount of damage
inflicted on its target and automatically starts firing as soon as an enemy
passes in range and area of effect of the weapon. Not all weapons can go into
overwatch (only machine guns?). Overwatch is disabled when ammo runs out or
the marine runs, turns, gestures or changes weapons. Chatting is still permitted
and the weapon will still fire even while typing. This lets the marines strategize
without immediate fear of death!</font></p>
<p><FONT SIZE=2><B>Queens lair</b></font><FONT SIZE=2>- The big room where the
queen lives. Aliens spawn here and is their base of operations. The aliens will
try to prevent the marines from finding or entering this room for as long as
possible so reinforcements can be gathered.</font></p>
<P><font size="2"><b>Resource injections (both)-</b> Both the marines and aliens
get intermittent resource points. The queen player gets all the alien resource
points, which he can use to produce drones or purchase upgrades. Every marine
gets their own amount of resources, with the commander getting more. The marines
then handle individual upgrades themselves and buy their own equipment. The
marines can also give resources to other marines if they are both within range
of a commander.</font></P>
<P><font size="2"><B>Regeneration </b> Gives all aliens (including the queen
and drones) automatic regeneration. Marines must continue to press attack to
prevent reinforcements.</font></P>
<P><font size="2"><b>Scuttle on ceiling/walls </b> Aliens of level 1 and 2 can
freely travel on ceilings and walls with no movement penalty</font></P>
<P><font size="2"><b>Stimpack</b> Reduces fatigue effects and temporarily increases
speed </font></P>
<P><font size="2"><B>Turrets - </b>After turrets are placed, overwatch kicks in
after a few seconds and the same sound plays. Turrets also have an audio sensor
and will track sounds that are close by. It will spin to aim at the nearest
sound, overwatch flipping on after it is still for a few seconds each time.
This lets aliens outwit turrets. Do turrets fire at any targets or only aliens?</font></P>
<p><font size="2"><B>Wounding </b> Both marines and aliens move slower and generally
are less effective when wounded. This is largely permanent for marines but can
be regenerated by aliens when available.</font></p>
<P><font size="2"><B>Victory conditions </b> The game is immediately won by the
marines if the queen is destroyed. The game is won by the aliens when all the
marines have been killed.</font></P>

<p><font size=2><b><font size="2">Possession-</font></b>Target another alien
not controlled by a player and hit possess key. You are instantly in control
of that alien. Any alien not controlled by a player, will attack marines within
a reasonable range but won't follow them. An alien player can group other
aliens with him by targetting it and holding the possess key. After a few
seconds, the alien will travel over to the player and will now follow the
player and attack the target the player is targetting. Only aliens of the
same type as the player can be grouped. In this way, a player can create and
control an army. He can also &quot;place&quot; aliens as sentries and set
up ambushes.</font></p>
<p><font size="2"><b>Infestation -</b> Can inhabit enemy player (host). Subject
loses ability to speak, gets fatigued quickly and triggers unified hive mind
sight for aliens. Unresolved: Is there a way to cure?</font></p>
<p><font size=2><b>Sphincters </b>- Aliens can enter the queen via sphincters
on her. Once inside, they can choose between multiple exits, each one leading
to a different part of the map. These sphincter doors exit through ceilings,
walls or floors. They can also be entered to quickly travel back to the queens
lair. They can be destroyed by marines</font></p>
<p><font size="2"><b>Unified hive mind (UHM) </b>- When alien sees marine, queen
and teammates get notified of general location via sound or display, enabling
aliens to stalk the marines. Aliens also always know about each others locations.
The player or enemy type is not disclosed. When drone is spawned, play sound
that can always be heard. When upgrade is purchased, play sound that can always
be heard. In each case, play chat message from hive mind to all players. Chat
messages to and from hive mind are silent so they cant be heard by marines.</font></p>
