Superheavy Laser Weapons
Sometimes you just need a little more firepower. Sometimes you just need to hatefuck a few new holes in your enemy. The Imperium of Man in particular has taken a liking to these weapons: from the humble lasgun to the powerful lascannon. But it was not enough. Upsizing the weapons several times and attaching them to their Titans, the Adeptus Titanicus are the supreme masters of these weapons.
Neutron Laser
Mounted on the Valdor and Cerebus Tanks.
Magma Cannon
The Volcano Cannon's smaller brother, the Doomhammer's Magma Cannon is still more than able to turn an enemy formation to dust and can even take on smaller Titans if needed.
Turbo-Laser
A single massive cannon strapped to the back of a Thunderhawk, it can deal massive damage to unprepared targets. And prepared targets.
Turbo-Laser Destructor
Two Turbo-Lasers strapped together to form a single destructive weapon. Most commonly used by the Warhound Scout Titan.
Laser Blaster
What's better than two Turbo-Lasers? Three of course! Fitted to the Reaver Battle Titan and above, these babies can REALLY fuck your shit up.
Volcano Cannon
What's that? The Laser Blaster is not good enough for you? Then what about the massive penis extension that is the Volcano Cannon? So massive that it has to be fitted onto Warlord and greater class Titans or suffer from energy shortages, and can be fitted onto the Shadowsword class Baneblade. Because big guns need to move fast too. Unfortunately, on tanks, there's no turret aiming: you point the tank where you want to shoot.
Hellstorm Cannon
So massive it can only be fitted onto the Imperator Battle Titan, this weapon is more than able to lay waste to entire armies, laying down 8 7" pie plates PER SHOT. You might remember this puppy from seeing it in Dark Crusade in the Imperial Guard stronghold level.
Vengeance Cannon
A very rare weapon fitted only onto Imperator or Emperor titans, this weapon has extremely high range, and firepower more than capable of destroying enemy titans in a single shot.
