Lore and Legends of the Dezzyverse

No, you got Traveller in my Battletech!

Two of my favorite games over my long gaming career are Traveller and Battletech. I’ve been playing both for over 40 years. Since I’ve recently moved to a new city, on a new coast of the US, and The 50th Anniversarry of Traveller is right-around-the corner. I’m starting a new campaign. With Battletech enjoying a renaissance, I’ve been throwing a healthy amount of Big Stompy Robots in my Science Fiction Adventure in the Far Future.

The setting for this campaign leans more toward the Third Imperium than the Inner Sphere. Specifically my favorite era in Traveller’s Third Imperium, the Hard Times. I talked a bit about this back in June. The elevator pitch is, the Hard Times are a relatively brief period in the Third Imperium that takes place at the end of the Rebellion War. Technology and society are skidding towards a second Long Night in the Shattered Imperium of Megatraveller.

How These Lego Bricks Fit Together

Battletech’s setting features giant, piloted robot war machines called Battlemechs. They run between 20 and 100 metric tons and are powered by big fusion engines. They’re a lot more on the “space-fantasy” side of science fiction, but there’s a heavy layer of gritty over them. Sort of like Star Trek, there’s a whole glossary of technobabble that sounds enough like engineering and “science!”

In Traveller terms, Battlemechs become practical around Tech Level (TL) 10. Fusion Power is practical here, which makes powering these war machines possible. The Inner Sphere setting ranges from a rough TL 10 or 11 in the classic Battletech era (between 3025 to 3062) to TL 12 at the height of the Star League (2750). The Clans were around the high end of TL12 and entering TL 13 so far as their engineering went, though the cluster of worlds from where they were exiled didn’t have the resources to fully exploit that level of development. Battlemechs as a practical war vehicle phases out by the time a civilization reaches TL 14, which is where fusion technology reaches it’s technological limits and more exotic power sources become commonplace.

The average Tech Level of the Third Imperium during the Megatraveller Setting (Imperial Year 1116) was TL 12 with the maximum TL at 15 (and a couple of places like the Darrian Confederation boasting TL 16). The Hard Times sourcebook for Megatraveller goes into detail about how the average Tech Level of the Third Imperium slides backwards. Which is a great parallel to the decline experienced by the Inner Sphere through their many Succession Wars.

Hey, Why Not Just Use the Battletech RPG Books?

There’s nothing wrong with Mechwarrior 1st edition, 2nd edition and Catalyst Games’ A Time of War, and Destiny games. I’ve run and played them (except Destiny) over the years, but my preference and love stays with Traveller. I’ve internalized the system a lot deeper than I have the Battletech systems (which is saying a lot, because I’ve internalized Battletech down to my frakkin’ bones!) For me, it’s the life-path character generation system in Traveller. I also talk about it in more detail in this essay, long story short, Traveller Character Generation tells a story through the dice better than using a point-buy system or laying templates over one another. Rolling up a Traveller almost always has a surprise in the character that makes it exciting to play on Session 1.

I also think in Traveller. The terminology comes more naturally to me, as we’ll explore shortly. As mentioned above, I have a good feel for where Battletech fits in the Traveller Universe, and it takes more work to fit Traveller in the Battletech universe. Advice to the new GMs out there, don’t be afraid to lean on what you know, running role-playing-games can be hard, no need to make it harder on yourself.

Some Broad Strokes

I’ll be using Traveller for character generation, setting info, personal combat and most space combat. I’ll be breaking out the hex-maps and Battletech Minis for vehicular combat. Both systems are 2d6 based, and the systems are pretty compatible. There are some fuzzy conflicts when dealing with Traveller small space ship combat vs Battletech’s Aerospace system, but I don’t think they’re insurmountable. Also, the Hard Times campaign isn’t about dogfights at the edge of atmosphere in a gravity well. The backdrop of War is context for the adventure.

Most of the time, the Traveller skill system is used rules-as-written. However, when on the Battletech or Aerospace battlemap, the system will switch over to Battletech: Total War with the following modification:

• Base Battletech Piloting is calculated using the character’s skill in Traveller Drive (Battlemech)
• Base Battletech Gunnery is calculated using the character’s skill in Traveller Heavy Weapons (Battlemech)
• Base Aerospace Piloting is calculated using the character’s skill in Traveller Pilot (Aerospace)
• Base Aerospace Gunnery is calculated using the character’s skill in Traveller Gunnery (Aerospace)
  • Battletech and Aerospace Piloting skill starts at 5. This is equal to Traveller Skill at Level 0 (without any Characteristic bonuses)
  • Battletech and Aerospace Gunnery skill starts at 4. This is equal to Traveller Skill at Level 0 (without any Characteristic Bonuses)
• For every Traveller Skill level gained, the corresponding Battletech/ Aerospace skill goes down by 1.
  • Example: A character with Traveller Skill Drive (Battlemech) 2, when moving over to the Battletech combat map, will have a Battletech Piloting skill at 3. (Base Battletech skill 5 – Traveller skill level 2 = 3.
• This can also be reversed when adapting the NPCs in a Battletech scenario to Traveller.
  • Mechwarrior Mungo Bogsbane has Battletech Piloting 4 and Gunnery 2. His Traveller skills are Drive (Battlemech) 1 and Heavy Weapons (Battlemech) 2.
• The Traveller Skill Jack of All Trades deserves special mention. Skill Levels in Jack of All Trades offset the penalties for trying skills without having at least Level 0 in the relevant skill. The full rules can be found in the Traveller Core Rulebook Update 2022 from Mongoose Publishing. Normally, characters need to have at least Skill Level 0 in the appropriate skill to operate a Battlemech, Aerospace vehicle or the weapon systems of either. These are too complex for someone who doesn’t have training to do anything more than flip switches, click buttons and yank levers in futility as the machine does nothing (best case scenario) or crashes in a catastrophic explosion (at worst..)
  Jack of All Trades allows a character to attempt an unskilled roll at a reduced penalty. Jack of All Trades 0 allows for the roll at a -3 penalty, with each skill level in Jack of All Trades reducing that penalty by 1. Until Jack of All Trades reaches Level 3, at which point the roll is at no penalty.
  When applied to Battletech’s Battlemech and Aerospace skills, These penalties are added to the base skill level. A character with Jack of All Trades 0 can roll Piloting at (5+3)= 8 and Gunnery at (4+3)= 7. Jack of All Trades 2 can roll Piloting at (5+1)= 6 and Gunnery at (4+1)= 5.

Gearing up for the Cockpit

The most critical piece of equipment for a Battlemech or Aerospace Pilot is their Neural Impulse Helmet AKA “Neurohelmet”. Neuohelmets provide direct neural links to the vehicle’s computer and sensors and are what makes Battlemechs and Aerospace craft more responsive than more conventional vehicles (even at high tech levels). Indeed, the Neurohelmet makes piloting Battlemechs and Aerospace craft possible in the first place. There are so many systems and subsystems that demand constant attention that no one person, or even a small crew of people could manage it all, but a Neurohelmet allows for a single pilot to control the vehicles full functionality.

A Neurohelmet is a TL 10 device that masses around 6 kg and costs 10 kilocredits (KCr, 10,000 credits). It is a huge, bulky, ugly, and fixes the wearer’s face straight forward. There is a window roughly the size of the wearer’s face installed that displays visual readout data into the user’s field of vision. Inside there are multiple contact leads which use the user’s own brain to move and drive the battlemech as an extension of their body. The helmet rests on the user’s shoulders, protecting the users relatively fragile neck from injury, but restricting any head movement.

The Neurohelmet’s bulk looks like it could deflect a direct hit from an Advanced Combat Rifle round. That is if the bullet wouldn’t damage all the internal electronics connected to the user’s brain. The Neurohelmet is not armor. Not even when deactivated. Its bulk comes from the complex hardware that creates the technological miracle which allows a human to control a titan.

At TL 11, the Neurohelmet becomes safer and smaller. It’s no longer a rat’s nest of cabling connected to a six kilo dome. It’s half the mass that it was at TL 10, while direct connection through ports from helmet to cockpit are still necessary, a lot of the connections are wireless.. There remains safety bracing that protects the neck, but the user is able to turn their head and enjoy a restricted range of motion.

AT TL 12, the Neurohelmet is half the size of the TL 11 helmet. It still fully covers the head, but does not require bracing to protect the neck. There is still neck protection, but not to compensate for having six extra kilos on your head. Direct connections to the cockpit have been reduced to one, two or three, depending on the model of the helmet. The user has a full range of head motion.

Cybernetic Neural Impulse Cranial Implants (“NICIs”) are also TL 12 devices, and are cybernetic augments. The NICI at TL12 replaces portions of the pilot’s skull and cannot be removed. There is a jack-port installed to make a direct connection into the cockpit. Not counting surgery, the NICI costs 500 KCr. Using a NICI to pilot a Battlemech or an Aerospace vehicle gives the Pilot a +1 Dice Modifier (DM) bonus to Drive (Battlemech) and Pilot (Aerospace) checks. If using Battletech rules for tactical vehicle combat, add the +1 bonus to the roll (not the target number).

The Cooling Vest is TL 10, costs 500 Cr and allows a Battlemech Pilot to survive the blazing heat in the cockpit of a Battlemech. It’s little more than cooling tubes wrapped around the pilot’s torso which circulate advanced cryogenic compounds and keeps the vital organs from cooking in the pilot’s body.

Aerospace pilots wear an Improved Vacc Suit with enhanced temperature regulation since they often find themselves operating in the Vacuum of space or extremely thin atmosphere.
At TL 11, the Cooling Vest is replaced with a specialized Hostile Environment Suit. The cost is much higher (22 KCr) but the HEV Suit provides protection similar to the Vacc Suit which permits the Battlemech Pilot a lot more combat endurance and focus when away from supplies.

Some down-on-their-luck pilots try to make do with makeshift cooling vests that use cold-packs in place of circulated coolant. Cold-packs are, in essence frozen blocks of water ice or similar freezable material. The cost is almost negligible. Less than 20 Cr and the Tech Level to put one together is around 4. The pilot only needs a means to freeze and insulate the packs. However, fighting in a cold-pack vest only allows for ten-to-fifteen minutes of operation before any benefits are spent and heat exhaustion leading to stroke sets in.

Character Development

After each adventure, Each character may roll EDU 8+. If successful, the player can either advance one of their character’s skills by 1 level, or they can adopt a new skill at level 0. When advancing skills this way, remember no character can have more total skill levels than three times their combined INT and EDU.

Maintaining a Battlemech or Aerospace Craft

Outside of repairs and rearming, Battlemechs and Aerospace craft require regular maintenance. Similar to space and star ship maintenance, once per year the Battlemech or Aerospace craft needs to be overhauled at a cost equal to 0.1% of the new cost of the vehicle. Divide by 12 to calculate a monthly maintenance cost.

Example: A WHM-6R Warhammer Battlemech costs 6,070,984 Credits new. The yearly overhaul cost is 6,070,984 x 0.1% = 6,071 Credits. The monthly cost is 6,071 / 12 = 506 Credits.

A SL-17 Shilone Aerospace fighter costs 3,399,045 Credits new, the yearly overhaul cost is 3,399,045 . 0.1% = 3,399 Credits. The monthly cost is 3,399/ 12 = 283 Credts

Like a ship, skipping monthly maintenance risks a malfunction. For every monthly maintenance skipped, roll 2D + the number of months missed. On an 8+, the vehicle suffers a malfunction in the form of a critical hit, determined in the same manner as if the critical was suffered in battle. Using the Battletech chart, roll a location off of the Front/ Rear Critical table and apply a critical to the affected location.

Battlemechs in the Rebellion War and the Hard Times

Battlemechs and Aerospace craft are used by all the major factions in the Rebellion War. There are also countless Mercenary Outfits that use these war machines selling their services to the highest bidder. As implied by the Noble profession assignment above. Several Noble families possess ancestral Battlemechs and Aerospace craft.

When compared to the state-of-the-art TL 15 weaponry that was deployed in the first years of the War, Battlemechs and Aerospace craft were outclassed. A company of TL 15 Battle Dress equipped infantry, TL 15 Grav Armor or a squadron of TL 15 armed space fighters are far more efficient and effective than an equivalent formation of TL 12 Battlemechs and Aerospace craft. However, as the war escalated between 1119 3i (3rd Imperium) and 1121 3i attrition forced all factions to press second and third line vehicles and equipment to the front. Battlemechs and Aerospace craft were re-deployed to replenish the attrition of years of war.

When the War turned Black in 1122, Battlemechs and Aerospace craft became the instruments of scorched world strategies. Battlemechs as walkers were well suited to urban fighting, and the Aerospace fighters and bombers were very effective at everything from close-air support, escorting dropships, and orbital theaters. In a pinch they could be pressed into space combat. Hybrid Battlemech/ Aerospace vehicles, known by a variety of names, Veritech Fighters, Land-Air Mechs, Variable Aspect Mobile Suits and Hybrid Aeromechs, among others.

Before the Rebellion War, Battlemechs and Aerospace fighters held a measure of prestige in the Noble Houses of the Moot. Nobles would use them to settle duels while showing off their wealth and means, in a similar way the aristocracy have used antiquated weapons and skills to settle disagreements while flexing on the less affluent. During the Rebellion War, Nobles wanting to cater to the imperial sensibilities of Lucan, Margaret, or the Ziru Sirca were eager to raise Household companies like ancient Lords calling their Banners. As the war dragged on, these same Noble houses were employed to share their tactical and technical knowledge in designing, and fielding Battlemechs and Aerospace fighters.

In the Hard Times, the owners and employers of Battlemechs are in an excellent position to take over systems and pocket empires as Technologically Elevated Dictators. By 1125 3i, the major governments had retreated into core zones. leaving the Wilds open for pocket empires to develop. By 1130 3i, Virus has been released and was devastating the Imperium for the next seventy years.
