GURPS Mecha Extras
by David Pulver
Ruskograd: a ghost town in the Siberia tundra. Officially abandoned after a Soviet nuclear accident, Ruskograd is a covert headquarters of the international defense organization known as UNISTAR. Here, top-secret battle mecha are built, repaired, and kept combat-ready to deal with the alien marauders that swarm down from the stars. For UNISTAR's elite technicians and mecha pilots, the defense of Earth is an awesome responsibility.
The girl with the wild mane of zebra striped hair leaned against the battle mecha's leg and struck a dramatic pose. "The new spring fashion from UNISTAR!" Bobbi Greenland announced. "I give you: Seraph Delta 'Heavy Armor'!"
Shocked speechless, sergeant Mara Seito ignored the young mechanic to gape at her personal mecha. What had once been her mecha. When Bobbi Greenland had said "a few minor modifications," Mara expected tinkering with the beam cannon or sensors. But not this!
Her Seraph Delta was 33 feet tall, a humanoid machine with two arms, two legs and a turret-like head. But now its former sleek, graceful lines had vanished under plates of bolted-on ceramic armor. A steel angel had become an iron ogre, heavier and more menacing.
"What have you done with my Seraph?" Mara howled.
Bobbi Greenland smiled. It was always nice to be appreciated. "Mara, don't be slow!" she scolded. "I added some armor, of course. Well, quite a lot. 25 tons, actually."
"25 tons!?!" Mara was stunned - that doubled her machine's weight. "Bobbi, what were you thinking? I can't fly with that much armor! And it's got to cut ground speed in half!"
"Only by a third," Bobbi corrected. "If you're still hitting their Antarctic fortress tomorrow, you'll need armor more than speed. Going in, anyhow. But it's not a problem. Because - "
"You're crazy! What if I have to run for it? Or they try to?"
"No problem. You explode."
That did it! Mara started forward, hunting for a weapon. That servo-wrench would do . . .
"Wait!" Bobbi shouted, ducking behind the mecha's leg. "This isn't ordinary armor!" She peeked out, confirmed that Mara had stopped advancing, then tapped the blocky hull with her screwdriver. It made a hollow sound. "It's my latest invention. An exo-armor husk: ablative ceramic plates secured by explosive bolts."
Mara's eyes widened. "Exo - explosive? So if I want speed - "
"You blow the husk off. Boom, and there goes 25 tons!"
"Instant diet! Bobbi, you're a genius."
"You know it." The teenage inventor grinned. "But speaking of diets, being a genius makes me hungry."
Mara reached for her wallet. Flattery, a double cheeseburger and a chocolate shake was a small price to pay to keep UNISTAR's best inventor happy. Even if she was an alien.
There's something uniquely compelling about the concept of a humanoid fighting vehicle. This sort of mecha is more than a combat vehicle - it's a machine that lets its operator move and act in a human fashion, but with vastly magnified size and power. But unlike a super-powered robot, cyborg or mutant, the mecha pilot retains his human vulnerability. In fact, he can be anyone, from a veteran soldier to a teenage school kid. This is one reason mecha are such popular subjects for novels, comics, games and, especially, for Japanese animation ("anime").
GURPS Mecha provides guidelines for many different styles and types of mecha-centered campaigns, from the realistic to the completely over-the-top. Mecha pilots and their supporting cast aren't stinted either, with descriptions of all kinds of mecha-using professions such as armored troopers, techno-knights and mecha cops, as well as genre archetypes like drill instructors, idol singers, exotic alien warriors and engineers.
The most enjoyable part of the project was coming up with a ready-to-use campaign background. This is the world of Cybermech Damocles, where the secret agency UNISTAR uses advanced mecha to defend today's Earth against extraterrestrial mind-slavers. One of the figures in the UNISTAR story is their alien specialist, the youthful inventor Bobbi Greenland:

Bobbi Greenland looks like the girl next door, except for her habit of dressing in greasy coveralls and a tool belt, dying her hair in odd colors, and carrying a notebook computer. But she's more than a mecha-obsessed mechanic. Bobbi's real name is Moth, and she's an alien Del Karva. Her father is the Overboss Tostog, ruthless crimelord of the interstellar syndicate known as the Gebberoth. Groomed as her father's heir, Moth's eyes were opened to the Gebberoth's evil after she learned the diabolical fate planned for the inhabitants of planet Earth. Her flight in a stolen spaceship and crash landing in Greenland came just in time to deliver a warning of the alien threat. Now under the alias "Bobbi Greenland," Moth aids her human friends in their fight against her father's sinister plans, serving as Earth's resident expert on ultra-tech alien technology.
Here's one of her recent creations:
"Seraph Delta Heavy Armor" (TL9)
This is a custom variant of a Gebberoth light battle mecha which UNISTAR captured. Bobbi repaired it for use by UNISTAR, and has recently further modified it with an exo-armor husk. The upgrade means it can't use its stealth features until the husk is dumped, but it's now far more potent in a head-to-head slugfest. Its stats are identical to the Seraph Delta design given in GURPS Mecha, except as follows:
Exo-Armor Husk: Until dumped, this serves as an extra outer layer of armor with PD 4, DR 6,000 on the front, right and left body and PD 4, DR 2,000 elsewhere. The armor is ablative, but DR is cumulative with underlying armor. The exo-armor husk weights 52,800 lbs. and costs $442,400 to replace. This isn't cheap, but is worthwhile if it helps a $6,000,000 mecha survive!
Statistics: Loaded weight 50,482 lbs. clean, or 103,282 lbs. with exo-armor. Empty weight 46,992 lbs., or 99,792 lbs. with exo-armor. Loaded mass 25.24 tons, or 51.6 tons with exo-armor. Mecha volume 716 cf. Size Modifier +4, with arms +2, turret -1, legs +3. Price $6,688,125 plus $442,400 for exo-armor. HT 9. 11.4 yards tall, 2.4 yards wide and high.
Strength and Reach: Body ST 1,800, each Arm split ST 2,400/4,000 (with reach 10, damage thr. 241d, sw 243d).
Ground Performance: Speed 40 mph, gMR 1.5, gSR 2, Move 15/20, Jump Multiplier 5. Without exo-armor: Speed 55 mph, gMR 1.5, gSR 2, Move 15/27, Jump Multiplier 10.
Aerial Performance: None. Without exo-armor: Flight-capable. Can hover. Effective motive thrust 518 lbs. Lift ST 35. Aerodynamic drag 900, speed 65 mph, aMR 3, aSR 3, Move 30/32.
Space Performance: Space-capable. sAccel 0.5 g. Without exo-armor: Space-capable. sAccel 1.01 g.
GURPS Mecha includes a set of mecha combat and design rules fully compatible with those in GURPS Vehicles, 2nd Edition and GURPS Robots. There's also lots that's new: for instance, a mecha can be built to transform from a humanoid form into a fighter plane or motorcycle, or several smaller mecha can be designed to combine into a giant machine. Other special rules cover exotica like battlesuits made of energy fields, steam-age mecha, and baroque anime-style weaponry such as energy waves, wind cannon and giant shields. One system I'm quite pleased with allows scaling up any ancient melee weapon into mecha-sized versions. It should be useful for fantasy games as well, to give giants their own huge swords or axes.
Speaking of fantasy, mecha campaigns aren't limited to alien invasions, superheroes or interstellar mercenaries! With a little effort they can become an fascinating addition to other adventure settings. Here are two examples of "cross-genre" mecha designs:
Lorica Ultima "Virgo Dragonstar" (TL3+)
Created by a secret order of thaumaturgical engineers, the Lorica Ultima are giant humanoid fighting machines. The finest of them is the Virgo Dragonstar, which is inherited by the crown prince or princess upon their coming of age.
Virgo Dragonstar resembles a 20'-tall suit of ornate plate armor, armed with a huge rune-carved bastard sword. It is no mere statue: within its torso is the mecha's powerful mana engine, a solid rune-carved sphere of Orichalium, surrounded by ectoplasmic fluids drained from the spines of dragons. The explosive expansion and contraction of these fluids powers the mecha's mighty pistons and clockwork gears, all in accordance with the will of its operator, who sits within a control throne inside the giant's body. He or she views the world through a periscopic lens that looks out the crystalline vision-slit in the head.
Virgo Dragonstar differs from lesser Lorica Ultima in its possession of the "overload booster," which can be activated to supercharge the mecha's performance at the risk of burning it out. Also, its locked and hostile mind-interface means this mecha can only be safely used by those with royal blood!

I gave this machine fairly light armor, so a fight with an elder dragon or huge giant isn't a forgone conclusion! Here's another "low tech" mecha, for use in GURPS Cyberworld:
Fabrique-Europa M-203 "Borgjager" (early TL8)
"The M-203 is a military powered suit designed to enable an unaugmented soldier to counter cybernetically-enhanced opponents or sustain a rapid dismounted advance under hostile fire while carrying heavy weaponry. A trooper in an M-203 is better protected than a combat cyborg of equivalent cost, although the battlesuit is a larger target and its use requires extra training and maintenance. The M-203 "Borgjager" is presently undergoing evaluation by United Europe elite units, notably the Foreign Legion. Export sales show promise, the most recent being 36 suits plus spares to ProGov's NERCC, for the urban policing mission."
- Janes' Combat Mecha, 2046 Edition.
Urban policing? Buying a Borgjager for police work's like using nerve gas for crowd control. Oops. Guess NERCC does that too, don't they? Hey, want to bet them suits be wearing arctic camo real soon? Them Alaskans better watch their behinds.
- Erica Storm, Consensual Anarchist Weekly.
The Borgjager looks like a big suit of ultra-tech combat armor. Its legs are proportionately larger than a humans, and its head is studded with various sensor and antennae arrays.
Subassemblies: Two arms, two legs, limited turret.
