−	:A Directional Torso Mount acts as a somewhat more restrictive [[BattleMech Turret|BattleMech shoulder turret]], allowing any weapons in the mount to shoot in either the front arc or the rear arc, depending on the mount’s current facing. The mount’s facing is set at the start of the game, and can be changed at the same time torso twists are made. However, unlike a torso twist, it does not reset at each End Phase: the arc chosen remains until deliberately changed. The mount rotates with any torso twist as normal.	+	:The player should treat the unit with this Design Quirk as if it has as a [[BattleMech Turret|BattleMech shoulder turret]].
−	:Each time a location with a Directional Torso Mount takes a hit (Front or Rear), the player must roll 2D6. A result of 9+ means the mount is destroyed and its weapon locked in its current arc, in addition to the normal effects of the attack.	+	Anything mounted in the shoulder regions will be able to change torso facing, like any regular 'Mech torso. However, this torso facing does not return to its original facing. The player must declare that they've changing facing of the torso from its last position when the next turn occurs. Weapons mounted in either forward or backward direction will be affected by the change in torso facing. Each time such a torso is hit (be it in the front or back), the player must roll 2D6 to determine if the ability to change torso facing is disabled. A Directional Torso will be considered destroyed if the attacking player rolls a 7 or better on a separate roll after hitting the section.<ref>''BattleMech Manual'', p. 83: Directional Torso Mount - Information on Design Quirk</ref>

==Description and Summary== '''Design Quirks''' are an optional ruleset, first formalized in ''[[Strategic Operations]]''. A more complete list of quirks, both positive and negative was then included in the ''[[BattleMech Manual]]''. They are intended to increase the depth of gameplay, providing rules for otherwise unsupported features mentioned in game fiction. The idea is an old one, first established in the 'Mech descriptions in the original versions of ''[[Technical Readout: 3025|TRO:3025]]''. The ''[[Javelin]]''<nowiki>'</nowiki>s entry, for example, contained rules for an early version of the ''Unbalanced'' Negative Quirk.<ref name=TR3025>''Technical Readout: 3025'', Third Printing, p. 16: "Capabilities"</ref> Currently, a fairly comprehensive list of quirks exists for canonical designs, as published in the ''[[BattleMech Manual]]'', expanding on the list that ''[[Strategic Operations]]'' began. Volumes of the PDF-only ''Experimental Technical Readout'' series published during or after July 2011 (starting with ''[[Experimental Technical Readout: The Clans|XTRO:Clans]]'') include quirks for most units. ''[[Technical Readout: Prototypes|TRO:Prototypes]]'' first collected these. In addition, the ''TRO''s of the 3145 series gave quirks for all the units they presented. Several new Quirks were introduced in these sources, which are compiled (along with the ''TRO:Prototypes'' quirks) in the print version of ''[[Technical Readout: 3145|TRO:3145]]'' and ''[[Record Sheets: 3145 New Tech, New Upgrades|RS:3145NTNU]]''. ''[[Interstellar Operations]]'' added several items of Era-dependent equipment that grant one or more Design Quirks, rules for Quirks in ''Strategic BattleForce'',<ref name=IO296>''Interstellar Operations'', p. 296</ref> and (with the ''[[Alpha Strike Companion]]'')<ref name=ASC40>''Alpha Strike Companion'', p. 40</ref> clarified which Design Quirks apply to Drone units.<ref name=IO292>''Interstellar Operations'', p. 292</ref> In keeping with the more abstract nature of the Alpha Strike and Strategic BattleForce rulesets, the Quirk restrictions and rules in the ''Alpha Strike Companion'' and SBF are generally streamlined,<ref name=IO292/><ref name=ASC59>''Alpha Strike Companion'', p. 59</ref> and often very different than the BattleTech rules. The rules for these games are presented below if the points cost or game rules differ significantly. Some quirks are removed from both rulesets, with Strategic BattleForce having the fewest Quirks and BattleTech the most. Note that Quirks lack conventional balancing mechanisms, such as Battle Value. ''[[Strategic Operations]]'' merely encourages designers to balance positive quirks with negative ones of equal or greater value, though some canon designs do not. Both Strategic BattleForce<ref name=IO296/> and Alpha Strike<ref name=ASC59/> now require player-generated units to balance Quirk points, though some Quirks are irrelevant to battlefield performance and introduce possible imbalances to "one-off" games. ==Design Quirk Summaries== ==='''List of Positive Design Quirks'''=== <div class="gamerules"> <div class="Positive Design Quirks"> ===='''Accurate Weapon'''==== ''BattleTech:'' :The Accurate Weapon Quirk marks a weapon or weapons bay as having exceptional design or construction quality.

All arm-mounted weapons on the BattleMech are fired from one Level above the terrain, instead of two Levels as normal. In addition, the unit's Arms are covered by partial terrain or water as though they were Legs. :'''Applicable to:''' BattleMechs and IndustrialMechs with arm-mounted weapons.

That date indicates when the unit with the Obsolete Quirk went out of production, and from that date onwards units of that type become increasingly difficult to maintain. Rolls to repair the unit, obtain replacement parts or even locate replacement parts become increasingly difficult for every fifteen years the unit has been out of production, and for every twenty years the unit has been out of production the resale price of that unit drops substantially. If a unit goes back into production at any point after becoming obsolete it takes a decade for the effects of the Obsolete Quirk to be negated.<ref name=RS3145ntnuP14-5>''Record Sheets: 3145, New Tech, New Upgrades'', pp. 14–15</ref> :'''Points Rebate:''' 4 :'''Applicable to:''' All unit types.<ref name=RS3145ntnuP14/> ''Alpha Strike:'' :All repair and salvage rolls are increased by a flat +2 penalty.

It also has difficulty moving through certain terrain without receiving damage, and cannot take cover as effectively as other units of its type. In Alpha Strike, Oversized units have more difficulty dropping troops as well.<ref name=ASC66/> :'''Points Rebate:''' 3 :'''Applicable To:''' Heavy and Assault 'Mechs and Combat Vehicles, and Medium-sized Support Vehicles.

In any situation where the unit has to check for hull breaches and/or flooding the unit attracts a penalty to the roll, and even units that would not normally be susceptible to such rolls are forced to check because of this Quirk. In addition to having to check in each situation that generates such a roll, units with the Poor Sealing Quirk must also make an additional check the first time they enter a hostile environment, suffering potentially catastrophic damage if the roll is failed.<ref name="RS:3145ntnuP15"/><ref name=ASC67>''Alpha Strike Companion'', p. 67</ref> :In SBF, only the breach roll penalty applies.<ref name=IO299/> :'''Points Rebate:''' 2 :'''Applicable to:''' BattleMechs, ProtoMechs, Battle Armor, Combat Vehicles and Support Vehicles.<ref name="RS:3145ntnuP15"/> ===='''Poor Targeting (Short, Medium, and Long)'''==== :Units with this Quirk suffer a penalty to any to-hit rolls made in the appropriate range bracket, as a result of poor targeting capabilities.

Ramshackles randomly will have a nonphysical negative quirk applied to them per battle, applying one type of negative quirk, such as EM Interference which remains in effect until the end of the battle.<ref>''BattleMech Manual'', p. 88: ''Design Quirks''</ref> :'''Points Rebate:''' 3 :'''Applicable to:''' BattleMechs, IndustrialMechs ===='''Sensor Ghosts'''==== ''BattleTech'' and ''Alpha Strike'': :The sensor suites on units afflicted with the Sensor Ghosts Quirk are prone to generating ghost images, suffering severe targeting penalties when the unit tries to make shooting attacks.<ref name=SOp199/><ref name=ASC67/> :A malfunctioning Star League Advanced Neurohelmet can cause a unit to gain this quirk.<ref name=IO69/> :'''Points Rebate:''' 2 :'''Applicable to:''' Aerospace fighters, BattleMechs, Battle Armor, Combat Vehicles, DropShips, JumpShips, Small Craft, Space Stations, Support Vehicles, WarShips<ref name=SOp197/> and ProtoMechs.<ref name="RS:3145ntnuPMQT"/> ''Strategic BattleForce'': :Causes penalties to hit and in the Detection Phase if more than half of the unit has the Quirk<ref name=IO299/> ===='''Slow Traverse'''==== BattleMechs with this quirk have a slower than usual [[BattleMech Turret]] as a result they can only rotate one hex per turn, unlike the normal full range of motion.<ref>''BattleMech Manual'', p. 89: ''Design Quirks''</ref> :'''Points Rebate:''' 1 ===='''Static Ammo Feed'''==== :A crude ammunition-feeding system prevents this unit from swapping the ammunition types fed to one or more weapons in combat. The owning player must select and use a single ammunition type for the unit before the game. In BattleTech, the quirk can be taken multiple times, with each affecting all weapons of one type on the unit. In Alpha Strike, all weapons lose the ability to choose ammo types.
