Speed: 4

Jump Jets: No

Weapon Systems

Plasma-Imbued Ion Sword (right arm)4d12 plasma +8 heat
Arm Laser Cannon (left arm)3d10 laser +7 heat
Dual Cryo Cannons (left torso)3d8 cold +4 heat
Shoulder Miniguns (right torso)4d6 kinetic +5 heat
Quad-Missile Mortar (center torso)6d10 explosive +6 heat
Sonic Screech Array (head)5d8 thunder +10 heat

Special Systems

Fission-Antimatter Core, CASE II (Cockpit Shielding), Targeting Computer, Bioluminescent Vein Network, Ion Field Amplifier, ECM Suite

On Hit: Sonic Screech: All enemies within 3 hexes must make a Piloting roll or suffer -2 to hit for 1 round. Ceramic and composite armor takes double damage.
On Critical Hit: Ion Surge: The Ion Field Amplifier overcharges the sword or pulse bolts, adding 2d12 bonus energy damage and ignoring 10 points of armor.
Activated: Missile Barrage: Launch all 16 missiles (8 warheads each). Each target in a 4-hex radius takes 8d6 explosive damage. This weapon system is expended after use.
Passive: Cryo Suppression: Dual Cryo Cannons reduce the Leviathan's own heat by 4 each round they fire, offsetting other weapon heat.
On Overheat: Core Breach Warning: If heat exceeds capacity, the Fission-Antimatter Core vents, dealing 6d8 energy damage to all adjacent units and resetting heat to 20.

The BM-X9 Leviathan is an assault-class biomech. Each round, total heat from fired weapons must not exceed 50 or the Core Breach Warning triggers. The Sonic Screech and Plasma Sword may not fire in the same round. Quad-Missile Mortar fires 4 missiles per activation; the mech carries 16 total (64 warheads). Cryo Cannons passively offset 4 heat per round when fired. The Ion Field Amplifier may be applied to one weapon per round as a free action, granting the on_crit Ion Surge effect to that weapon's next hit. The tail grants +1 to Piloting stability checks. Bioluminescent Veins provide passive sensors (no ECM penalty to targeting). CASE II protects the pilot cockpit from internal explosions.

“A 70 foot tall biomech with a mouth full of razor sharp teeth that can cut tungsten and release a sonic screech that can shatter ceramic and burn through metal. It also has a fission antimatter core located in the top center of the chest. Right above that is the pilot's cockpit and then it has these somewhat bulky legs with a tail and it has these glowing blue veins all around it. On its left arm it has a laser cannon and two artillery cannons on the sides of that and then it also has a a plasma imbued sword with an elongated shell launcher that has an ion field right above it and it shoots plasma and say let's say pulse rifle that has an ion field right above it. It shoots plasma bolts that go through an ion field for maximized damage and then on the back it has a mortar that can launch four missiles at a time. The mech has 16 missiles each of which have have eight warheads inside them to do a lot for maximum damage. Right below that right above that on the shoulders it has these two cryo cannons and right above the shoulders are these two miniguns And it also has a tail.”
