Titan Weapons - Specialised Weapons: Carapace Landing Pad - Some Battle Titans transform one of their carapace weapon hardpoints into a small landing pad. This structure is used for two purposes. Its primary function is as a launch point for assault troops embarked on the Titan. Protected by the Titan's void shields, assault troops can be brought within jump range before they attack. The reduction of casualties from defensive fire to a minimum makes this a favoured method of assaulting heavily-defended positions. Its secondary function is to act as a landing pad for Land Speeders. A Carapace Landing Pad can carry up to four infantry squads and two Land Speeders. The Carapace Landing Pad is also utilised for a small VTOL (Vertical Take Off and Landing) aircraft, similar to a Land Speeder. This small aircraft is directly linked to its parent Titan's Mind Impulse Unit, granting the Titan's princeps an extra set of eyes and ears that can provide invaluable information without having to risk a Scout Titan to obtain it.Carapace Mounted Multi-Lasers - Warlord-class Titans in built-up areas are sometimes fitted with Multi-Lasers replacing the rear banner mounting points. These act to cover the Titan's blind spots against infantry assault.Corvus Assault Pod - As a further extension of the theory behind landing pad launched assaults, the Corvus Assault Pod, or Corvus Module, was developed as an alternative arm mount for Titans. In essence, the pod is a boarding torpedo fitted to a Battle Titan's arm. When a building needs to be claimed relatively intact, a Titan fitted with a Corvus Assault Pod is the perfect tool for the job. The pod is designed to allow the Titan to carry a single detachment of troops right up to a building, and once the objective is reached, the Titan can ram the Corvus Pod through the building's outer wall, creating an entry point, and disgorge Mechanicus Skitarii warriors directly amongst the defenders via a drop-down ramp. The pod can carry up to four infantry squads.Centre Line Weapon Mounts - A common Warlord-class Titan variant is the replacement of the head of the Titan with a Deathstrike centre line Macrocannon mount. The Titan's crew reside in a carapace-mounted fire control tower or platform fitted with a relay. Deathstrike-variant Warlords are used for long-range fire support and bombardment duties.Deathstrike Cannon - The Deathstrike Cannon is a starship-grade Macrocannon fitted on a Warlord-class Battle Titan. A rarely-fielded conversion, it requires the whole head of the Warlord to be removed, and the cockpit to be installed on the top of the Titan's carapace instead. One of the Titan's carapace hard points is then fitted with an advanced fire control system tower. This configuration opens two additional hard points that can be used to mount additional Titan-grade weapons. The cannon's recoil is so powerful that it needs to be mounted along the centre line of the Warlord Titan. Despite the severe limitations this imposes on the Warlord, the Deathstrike Cannon's colossal range and power makes it a useful artillery weapon, able to obliterate fortifications or harass an enemy's rear lines and staging areas at extreme long range.Devotional Bell - A Devotional Bell structure is always carried by the Custodian Titan of a Titan Legion. Built from valuable and sacred Terran metals and annointed with a drop of the Emperor's blood, the bell acts as a mobile shrine for the Imperial Cult and a rallying point on the battlefield. The presence of a Custodian Titan in a battle is a complete anathema to daemonic intrusions into the material universe as it directly extends the Emperor's will and spirit to His mortal followers.Fire Control Centre - A Fire Control Centre is a battery of sensors, Vox-casters and MIU boosters fitted to a Titan's carapace hardpoint. It allows the Titan's princeps to better coordinate fire between multiple Titans, and even other Imperial forces if required. Since most Titans are ferociously independent, this is a rarely used form of tech-arcana, and is only fielded when the whole of a Titan Legion must be deployed to obliterate a truly mighty opponent.Hellstrike Cannon - The Hellstrike Cannon fires a massive shell that is loaded with a highly corrosive and inflammable mixture that is known appropriately as "hellfire." The shells are set to explode in mid-air just above the target, so that it splatters in as wide an area as possible with the deadly hellfire mixture. As the hellfire saturates the area it ignores cover, making it particularly potent against infantry in wooded areas or buildings. This fell weapon is wielded by Chaos Titans.Natrix Shock Lance - Based upon the Ursus Claw, the Natrix Shock Lance was designed as a more aggressive and less hazardous alternative to its parent. Modified with an oversized electromagnet powered by the Titan's reactor, the Natrix Shock Lance can deliver a pulse capable of temporarily overloading the target's systems, leaving it vulnerable to larger Titans.Psi-Pulse - The Chaos Subjugator-class Titan carries a strange array of weaponry, the most potent of which are the Psi-Pulse generators. These are studded with gems and enclose a honeycomb of membranes which resonate to the power of the Warp. The Subjugator uses its own link to the Warp to channel raw psychic power through the generators, creating a psi-pulse capable of punching through the thickest armour. Loping along the flanks of the battlefield, the Subjugator uses its psi-pulse to pick off enemy artillery before it can fire.Rubble Claws - Rubble Claws are auxiliary units clamped over the standard Warlord's feet to give it extra traction in treacherous terrain. Plus, due to its broader size, the Titan's feet can crush more enemy vehicles and infantry when making a stomping attack. Unfortunately, the extra weight of Rubble Claws degrades a Titan's performance somewhat as Titans wearing them aren't nearly as manoeuvrable as their unencumbered counterparts. Therefore, it is unable to make any charging attacks. The restrictions placed on a Titan's manoeuvrability means Rubble Claws are usually only fitted to Titans fighting in sieges and built-up areas.Siege Hammer - A Siege Hammer is a form of siege weaponry used by the Adeptus Mechanicus robots of the Legio Cybernetica and the Titans of the Collegia Titanica. These weapons, while differently sized depending on whether they are deployed on an Imperial robot or a Titan, are capable of pounding down enemy fortifications in order to create a breach for the entry of assault forces.Sinistramanus Tenebrae - The Sinistramanus Tenebrae, literally translated as "the Left Hand of Darkness", is a unique and nightmarishly powerful weapon mounted upon the left arm of every Warlord-Sinister Psi-Titan. It is a hybrid of strange technologies melded together by the Emperor's own hand and it is believed it is He alone that knows its true origins. When activated, the Sinistramanus Tenebrae requires the unified minds of the bound psykers aboard the Psi-Titan to focus its power, lest its destructive energies are let slip of their control.Titan Heads - The head of a Titan houses the princeps and moderati who control it. In the event of catastrophic damage the head of the Titan can be ejected to carry the Titan's crew to safety. All Titans carry a Heavy Bolter for anti-personnel work but there are a wide range of variant heads used by different Orders, some mounting heavier weapons or fitted with various devices such as a heavy weapon, a close combat weapon or a Corvus Assault Pod.Tormentor - The Chaos Questor-class Scout Titan possesses graceful arms that spread from its carapace, each tipped each tipped with a rapid-firing cannon called a Tormentor.Trident - The Trident is a Titan-grade melee weapon used by some Warlord-class Titans that originally served to bring rebellious Titans under control, but can prove extremely effective against an unsuspecting hostile Titan. It is a low-velocity barbed spear attached to a massive chain or cable that is in turn connected to one of the Titan's weapon hardpoints. It is thrown at a rebellious god-engine's legs. Slow enough to ignore Void Shields, it will hammer deep into the leg, and the Titan who threw it will then move backwards and rotate at speed in the hope of tripping the rebellious machine, taking it out of a fight without damaging it irrevocably. Once prone on the ground, the rebellious Titan can be accessed and deactived with much less risk, for it will not be able to rise or bring its armament to bear.Ursus Claws - Developed for use on the voidships of the World Eaters Legion, smaller scale variants of these barbaric weapons were used to great effect by the Titans of the Legio Audax. They were effectively giant spears that could be fired from one Titan to penetrate the hull of another Titan and capture it intact. Although the Ember Wolves were the most infamous users of Ursus Claws, both Loyalist and Traitor Titan Legions adopted their use as the Horus Heresy progressed, recognising the benefit of capturing opposing god-engines to replenish their mounting casualties.
