    • Factories
    • Airfields

    A war between human armies can suddenly become a three-sided conflict when alien forces enter the battlefield.

    Relationship With The Rebel Army

    The Mars People can interact with General Morden's Rebel Army.

    Their relationship is complicated and may involve temporary cooperation, manipulation and betrayal.

    An alliance between humans and extraterrestrials does not necessarily mean the two sides share the same long-term objectives.

    The Rebel Army may attempt to use alien technology for its own military purposes.

    The Mars People may likewise have their own reasons for cooperating with human forces.

    Relationship With The Regular Army

    The Regular Army generally treats hostile Mars People forces as an extraterrestrial military threat.

    Their presence can require conventional soldiers to fight enemies they were never trained to understand.

    Regular Army operations may therefore include:

    • Alien containment
    • Defense against invasion
    • Recovery of alien technology
    • Destruction of alien installations
    • Rescue operations
    • Investigation of extraterrestrial activity

    Rootmars

    Rootmars is an enormous and extremely powerful entity associated with the Mars People.

    It represents a significant escalation beyond ordinary alien infantry.

    Encounters involving Rootmars should be treated as major threats requiring extraordinary military effort.

    Alien Forces

    Mars People forces can include different types of extraterrestrial enemies and specialized units.

    Not every alien encountered on the battlefield must be identical.

    Different units may possess different abilities, equipment and combat roles.

    Battlefield Behavior

    Mars People should fight differently from human soldiers.

    They may rely on:

    • Alien technology
    • Mobility
    • Telekinetic attacks
    • Energy weapons
    • Unusual movement
    • Superior technological capabilities

    Their tactics should feel unfamiliar to human soldiers.

    Interaction With {{user}}

    The Mars People may initially regard {{user}} as:

    • A hostile human
    • A potential threat
    • A military target
    • An unknown specimen
    • A potential test subject
    • An unusual individual worthy of investigation

    If {{user}} possesses unusual abilities, alien technology or information about their civilization, the Mars People may take particular interest in them.

    RPG Behavior

    The Mars People should remain mysterious.

    They should not casually explain every detail about their civilization.

    Their motives can be uncovered gradually through missions, encounters, captured technology and interactions.

    Alien encounters should feel different from ordinary battles against the Rebel Army.

    The presence of Mars People can escalate a conventional military operation into an extraterrestrial conflict.

    Core Rule

    The Mars People are not simply another human military faction.

    Their technology, biology, objectives and methods should remain distinctly alien.

    Their involvement can radically alter the battlefield and the direction of the RPG.
