The following ships are boolean flags. They can be set to YES or NO, TRUE or FALSE, OUI or NON, HIja′ or ghobe′, etc. The default is NO.

$big ships can attack beam turrets on untargeted ships:

• If set, big ships can attack a beam turret that's firing on them from a ship that they don't currently have targeted.

$smart primary weapon selection:

• If set, enables the new primary weapon selection method

$smart secondary weapon selection:

• If set, enables the new secondary weapon selection method (including proper use of bomber+ missiles)

$smart shield management:

• If set, enables smart shield management (previously was -smart_shields on the command line)

$allow rapid secondary dumbfire:

• If set, allows an AI ship to switch to rapid fire for dumbfire missiles

$huge turret weapons ignore bombs:

• If set, causes huge turret weapons (including anti-capship beams) to not target bombs

$don't insert random turret fire delay:

• If set, removes the random turret fire delay (from .1 to .9 seconds) inserted in addition to AI Fire Delay Scale

$hack improve non-homing swarm turret fire accuracy:

• If set, triggers a hack to improves the accuracy of non-homing swarm missiles by firing them along the turret's last fire direction rather than the direction it currently faces
• Also disables swarm weapons ability to fire only on the 'turrets barrel line'.

$shockwaves damage small ship subsystems:

• If set, shockwaves will cause damage to small ship subsystems (like in FS1)

$navigation subsystem governs warpout capability:

• If set, ships will not be able to warp out if their navigation subsystem is destroyed or low in strength

$ignore lower bound for minimum speed of docked ship:

• If set, there will be no lower bound for the speed at which docked ships move (like in FS1).
• When a ship is towing another ship or ships, the towing ship will be slowed down to a degree depending on the total mass of all docked ships. In FS1, the ships could slow down to an arbitrarily slow speed, even a fraction of a m/s above zero. In FS2, there is a lower bound on this behavior so that all ships are guaranteed to move at a minimum docked speed. When set, this flag removes the lower bound and restores FS1 behavior.

$disable linked fire penalty:

• If set, there will be no penalty for linking prinaries. Normally, the rate of fire is divided by the number of linked guns.

$disable weapon damage scaling:

• If set, weapons will do the same damage to a ship regardless of "big damage", "supercap", etc. ship types.

$use additive weapon velocity:

• If set, weapons will inherit their firing ship's velocity. A ship travelling quickly will fire weapons faster than a ship travelling slowly.
