Version 3.4.3 update
Vesta acquisition. In response to the verbal from the autopilot, Dieter Ulans flipped his datavisor in front of his eyes and prepared to take direct command of the massive ring of lasers and reaction engines that was Hercules. He hit the juicer button and felt the rush as the drugs began to wash into his veins. “Com’monn jockey juice!” he whispered and then began to croon: “All my thoughts of you, you, you — all that I’ve sought is you, you, you.” The tiny green symbols on the datavisor began to zip past his eyes at an increasing speed.
From the rulebook to Battlefleet Mars 1977 – Essentially the Expanse setting but 39 years before it aired.
There are lots of changes all over the rules, too many to mention. Sections have also been rewritten, gotten new or updated illustrations or have been rearranged, to clarify and simplify without actually changing too much.
As always, read the front page to get a feel how the game works. Then, read pages 2-3 which cover tasks and initiative, very important to grasp. From then on, simply start playing a turn and read as the turn progresses, the rules are written in turn sequence order.
You can download it all here, as usual, with the updated designs, maps etc.
The task system has gotten a facelift and a slight change to what Miss margins give what result. All tasks are now highlighted in red in the table columns to make them easier to find, they are also duplicated on the four reference pages at the back. All degrees of success or failure are now three points wide:
- Very Good You rolled at least 6 points above the target number.
- Good You rolled 3-5 above the target number
- Fair You rolled 0-2 above the target number
- Miss You missed by 1-3
- Bad You missed by 4-6
- Very Bad You missed by 6 or more
The movement rules are basically the same as before but rewritten and clarified with step by step illustrations on how movement is performed. The section on plotting has also been clarified and with a detailed example illustration showing all aspects of plotting.
Fractional thrust Ships don’t come with Thrust in increments of whole Gs, fractions in increments of 0.25 Gs allow the ship an extra G on certain turns of every group of four turns. The mapsheet holds helpers for this and there is also check-boxes for fractional thrust, loaded and unloaded, on the ship Datacard too. All ready-made designs have these already filled in for you. A ship with 1.25 Gs of thrust would thrust 2 G on turn 1 and 1 G on turns 2-4, 2.5 Gs of thrust would thrust 3 G on turn 1 and 3 and 2 G on turns 2 and 4. A ship with 0.75 Gs of thrust would thrust 1 G on turns 1, 2 and 3 but cannot thrust on turn 4 of every group of 4 turns.
As damage to Thrust and Power affected how many Gs a ship could thrust this has been changed too, so you don’t have to recalculate what fractions to use as you get damage. Now Thrust and Power damage affects how many turns in a row you are allowed to thrust. All, 2 turns , 1 turn or not at all for No damage, Light, Severe or Critical damage. Plotting rules teach you to draw a circle around your ship whenever it drifts and thus reset the clock on thrust.
The fundamentals of the sensor rules remain the same, just clarifications and better examples. The only changes I can think of is that you no longer can use your Visual/IR and Radar sensors when popped in. On the other hand, ships may now pop in at any time during a turn as long as they haven’t used their weapons yet. Ships lose any tracked enemies and any launched missiles when popping in but as you know the vector and position on your targets when they were tracked reacquiring them should be fairly easy.
Oh, one more thing. Intercept now allow 2×2 scans, 2×2 square scans are +2 (+4 for radar), 2×2 boxes are -2 (-4 for radar). I didn’t allow them before because they didn’t have a clear center but showing where your scan is located should pose no problem anyway.
The plotting rules now teached how to refer to boxes and sqaures on the map, using the legends on the map. To efer to the top left box of the map, say “Ay-one”, to refer to the bottom left square of the box where the latrge planet is in say “Dee-six one-five”. Always use column-then-row for the boxes followed by column-then-row for the individual squares.
The combat section has been rewritten and lots of die modifiers have been removed or baked into other rules. How much a ship thrusts no longer affect how hard they are to hit, we simply give a +2 DM on attacks, and defense when drifting.
Underpower When a ship didn’t have enough power to use all their weapons when thrusting or drifting we previously used two DMs, peculiarly placed low on the Datacard and was often forgotten (I admit to cobbling it in wherever there was room).
Now, Underpower is one of All+, All, 2 turns, 1 turn, No fire, ships have separate Underpower ratings for Thrusting, Drifting or Jump prepping (more on that in the optional hyperspace rules). When a ship has Severe damage in its power location its Underpower rating is one level worse, All+ becomes All, All becomes 2 turns and so on.
Damage has changed considerably in this version. Ships now have only one DAB (Damage ABsorption) rating for the entire ship instead of one per location, ARM (for ARMour) is still per location and sometime even have two values, popped out / popped in for Surface damage, full power / silent running for high powered power locations representing their vulnerable heat radiators.
How do we handle different damage at different locations then? We have three separate columns on the damage table, one for Hull, one for Crew, Core and Power and one column for Surface and Thrust.
Aerobraking & landing
I seem to rewrite the aerobraking and landing rules once every two weeks or so but now I have something that I feel I’m done with as it is fairly simple yet contains everything I want it to do. Docking and ramming has been moved to the optional rules as they tend to be used more rarely. I have increased the safe speeds for aerobraking somewhat so they become more useful. New illustrations and two examples help clarify things. there is even a little section dealing with your ships signatures when landed and how your sensors work through and atmosphere. Yeah, landing on the day side of a planet with atmosphere will make you harder to scan but your Visual/IR sensors will be blind from the bright atmosphere.
Campaign rules If you want to play a series of Intercept scenarios and have your crews and/or entire navy improving is skill from experience this is for you. The rules merely deal with how to track skill improvements but also skill loss from crew damage. There are also some bare bone outlines of scenarios to help you with ideas. This system is what we use at work when playing and interconnected series of space fights.
Redlining Have you ever wanted to pull all the safeties as captain Phillips did when Somali pirates tried to intercept him, or yell at your engineer ordering him to once again do the impossible? In other words, have you ever wanted to redline your engines?
You decide if you want a 50% boost to your thrust this turn or doubling it for a turn, the latter is of course more dangerous. There is a considerable likelihood that your thrust location will get a CD (Continuing Damage) ie ‘fire in the engine room!’ and you may even risk damaging your engine. Redlining, as well as powering up from silent running and the usual jury-rigging of battle damage is done by your trusty Repair Crew.
Hyperspace The rpg Traveller has a faster than light system that works by travelling far away from any planet, jumping into hyperspace, spending about a week there and exiting somewhere else parsecs away from where you started. I have shrunk how far one must travel to safely jump to fit planet and safe jump onto an Intercept mapsheet. There are some fairly detailed rules about how to jump, fuel use, astrogation, misjumps etc and where you will end up. In my system, all jumps have you end up somewhere, near a gas giant, planet or asteroid, even when you misjumped into an ’empty’ parsec hex in the original Traveller.
If you are playing a Traveller campaign I suggest you not only replace the space combat and starship movement rules with Intercept, replace the hyperspace rule too.
There are tons of changes to the design system too. Most importantly I think you get all the important design spec data in one place. As shown by this part from the Free trader design spreadsheet available in both InterceptBundle and Designs.
Three little orange dots appeared on the screen. Look at him — blowing out decoys even though he knows we’re out of maneuver — that Kolnichok, grinned Dieter. So which one is you, Joey, and which are the aluminum balloons? (Seven dots grew on the screen, all had slightly different vectors.) Now you know my heater can take you in one flash and you also know that one zap is all I’m going to get. And if I take it you’ve got a perfect excuse to blow me up for the honor of the company rather than recapture valuable property for the accountants. So what’s it going to be? I think you shot off too many balloons too early Joey — cause the other ones aren’t making the course correction you just did. Ain’t that you, Joe?
Ulans squinted and tapped his foot.
