Default GURPS 3e & 4e Metal Gear Solid

I'm interested in running a GURPS Metal Gear campaign, and I haven't really seen many posts on the subject before. So I'm starting this thread so that the Characters, weapons, locations, (and most importantly, mechs) of the Metal Gear series can be ported to GURPS 3rd and 4th edition. I've created Metal Gear REX using GURPS 3e Mecha and will post the stats shortly, and ask for suggestions on how to improve it.

Here it is:

Metal Gear Rex [TL8+3] (GURPS 3e)
(All components are TL8 unless otherwise specified.)
[*]Description (!Spoilers!):Metal Gear REX was a Metal Gear prototype that was jointly developed by DARPA and ArmsTech for the United States Army in the early 2000s. In the early 1960s, Soviet scientist Aleksandr Leonovitch Granin created designs for a REX-like bipedal tank. However, Colonel Volgin of GRU rejected his ideas in favor of Nikolai Stepanovich Sokolov's Shagohod. Drunk and bitter, Granin sent his designs to an American colleague, revealing this to CIA operative Naked Snake during Operation Snake Eater. The development of REX itself was foreseen in a psychic premonition by Elisa and Ursula during the San Hieronymo Incident in 1970.

Some time after Solid Snake's encounters with TX-55 Metal Gear in 1995 and Metal Gear D in 1999, an attempt to carry out a Metal Gear project within the United States had been planned but was officially scrapped yet convinced the private weapons company ArmsTech that building one for the U.S. Army would be a very profitable venture. ArmsTech had been in a dire state financially, with the possibility of a hostile takeover becoming apparent after failing to obtain a contract on a new line of fighter jet for the U.S. Air Force. Likewise, the Department of Defense agreed to its development due to the defense budget being slashed by 15% and thus being forced to allow the private sector to develop their weapons for them.

In 2002, DARPA Chief Donald Anderson was heavily bribed by ArmsTech to back the Metal Gear REX project. DARPA funded REX's development covertly, using part of the United States' black budget.The nuclear weapons disposal facility on Shadow Moses Island was constructed to conceal the development of Metal Gear REX. Its rail gun was based on technology developed for the SDI, having been successfully miniaturized in a joint venture between ArmsTech and Livermore National Labs. Livermore Labs also developed a new type of nuclear weapon for REX using NOVA and NIF laser nuclear fusion testing equipment and supercomputers.

One of the main goals of developing REX was to overcome a global trend in military downsizing at the time. REX was a self-mobile launch platform capable of using its massive rail gun to launch a nuclear warhead contained projectile package with a low radar cross-section, and without the need for a rocket propulsion system, The launch event was also undetectable by satellite thermal imaging, unlike the massive heat signature characteristic of ICBM launches. It could give any country in the world a first-strike capability that other nations would find hard to counter. This also exploited a specific loophole that existed in anti-nuke treaties, since projectiles fired from a rail gun were not technically ICBMs, so the START treaties imposing limitations on ballistic missiles did not apply.

During REX's development, the Metal Gear engineers became concerned of what would happen if REX, after it was completed and doing solo ops in the field, was detected by the enemy and forced to engage in close range combat against conventional forces. They then decided that they could make REX's hull a weapon in itself. Although the program was completed, and had gotten fantastic results from supercomputer simulation, the military shelved the project before they could even install it (as the military viewed it as not being part of their regulations). However, REX's chief engineer Hal Emmerich secretly uploaded the data into REX anyway. Although the first actual prototype for REX was developed in 2005, it went through multiple prototype stages in VR while it was still in the design stage to correct various flaws before being developed. As REX was primarily tested via VR simulations, the Pentagon and ArmsTech needed to perform live testing to compare the simulation data with actual test results. Because of this, they started a field exercise at the remote military facility on Shadow Moses Island.

I'm finding that block of stats nearly unreadable. Any chance you could add some line breaks to make it more readable? Also, for those of us who never played Metal Gear, could you give an explanation of the role for this thing and what it's meant to look like?

AFAICT from the one I've seen and some research, they're big honking nuclear armed mecha, and their primary role is as a MacGuffin.

Yeah, I caught that it was a mecha but are they MechWarrior style RealRobo mecha, Robotech/Macross style transformation mecha, Evangelion or Escaflowne style SuperRobo mecha, or something in-between like a Gundam?

More like real life mecha, theyre weapons platforms like modular tanks. Take a tank, remove the treads, oversize some firing support struts and call them legs then stick its weapons on the sides instead of mounted directly to the turret.

Closest is MW but without the humanoid shapes, airplane fuselage shapes, etc.. MG mechs are also much shorter, but less agile. They can be transported by other vehicles, fit inside buildings, and generally arent as tall as a moving housing development with legs and face paint. It looks like something the American military would commission from General Dynamics.

Rex stands at about 13 meters height. Which is shorter than MW's light mechs if I'm not mistaken.

I've got a hefty bit of bias because I despise the super-robo genre and my bar is set incredibly high on the 'real robo' genre. Any rudeness detected in this post was subconscious and not at all intentional.

If you're a fan of TVTropes, Metal Gear (especially Rex) belongs more in an Oversized Walking Tanks genre.

Default Re: GURPS 3e & 4e Metal Gear Solid

I second tbrock1031 notion that it would help if you cleaned up that stat block a bit. I'm wasting too much brain power trying to make heads or tails of anything.

But to help out a bit here's some 4th ed. stats for ol' Rex's weapon load out.

GE GAU-8/A, 30173mm

Damage: 6d6(2) pi++ inc
Acc: 6
Range: 3,000/10,000
Weight: 618/1,784
ROF: 65!
Shots: 1,174
ST: 35M
Bulk: -12
Rcl: 2

Dmg is for the PGU-14/B APDU cartridge; the PGU-13/B SAPHE has Dmg 6d5 pi++ with 3d+1[1d+2] cr ex. Note that RoF is fixed at 65. The original gun installation had RoF 35/70, but this was changed in the 1980s. I haven't been able to find official figures on the power need to run a burst with the avenger.

AGM-114 Hellfire

Damage: 6d4(10) cr ex
Follow up 6d16(10) cr ex
Linked 6d6 cr ex
Acc: 6
Range: 490/14,000
Weight: 108
ROF: N/A
Shots: N/A
ST: 19M
Cost: $110,000

Note that it has both semi-active laser homing and a milimeter wave radar but I haven't found enough info on the radar yet to try to stat it.

100mW Free Electron Laser

Damage: 8d12(2) burn
Acc: 18
Range: 350,000/1,050,000
Weight: 1.9 tons
ROF: 1
Shots: N/A
ST: 146M
Bulk: -10
Rcl: 1
Cost: $3,700,000

Notes: I treated that laser as having the super science options to get it to fit on Rex reasonably, it's almost 15 tons without it! Needs 322mW to power each shot.

It's gonna take me a while to stat out the rail gun so I'll come back to that later. The nuke it launches though wouldn't be that hard to stat. While it's never stated what yield it was I'm guessing it's around 200kt based on what the Metal Gear wiki says so I'll go with that and it was stated that is was a laser pumped "Pure fusion" bomb so it will have negligible fall out.

200kt Pure Fusion blast
Damage: 6d28,000 cr ex
Linked 6d26,000 burn ex rad sur (Note divide burning explosive damage by 2 times distance in yards rather then 3)

As for the weapons I did stat up, the Avenger is from Hans himself so it's pretty much official, the stats for the Hellfire was derived by me but was stated using pretty much the same rules used for shape charges in High-Tech (They're actually pretty easy to reverse engineer), everything else was from wikipedia, should work well enough for game purposes but if I have the time I'll try to find more trust worth figures later. The lasers stats were figured by using the Blaster and Laser Design article from Pyramid 3/37 with power requirements figured by.... "sources" and the nuke stats are also figured from "sources".

I hope that this helps.

I changed it, is it more legible now? Sorry, it was my first post. Also, tbrock1031, if you Google the aforementioned Metal Gear Wiki and type in "REX" you can see pictures of it, or just search "Metal Gear REX" and you will get tons of images. I personally recommend playing at least MGS1 (there is a PC port available) or MGS1: The Twin Snakes (A remake with enhanced graphics on the Gamecube).

Finally, I'm aware 3rd edition is outdated, but the Spaceship design system didn't seem specific enough for something like a Metal Gear. Thanks for the 4e stats, Ryujin. I'm hoping to create a bunch of GURPS Metal Gear stuff independant of what version of GURPS you use. I still use the 3e books, because I don't have the money right now to invest in the 4e ones. The MTHEL-FE irks me a bit, as in the game it is a continuous beam rather than a series of 4 shots. Oh well. My version of REX's Railgun is a launch tube, as a 705mm gun would weigh far too much. The fact that it is electromagnetic is simply a special effect in these statistics.

The weapon statistics I took from the Metal Gear Wiki, as well as Wikipedia (The rotary cannon and both types of missiles exist in real life, after all), and tried to get their statistics as close as possible by fudging the numbers a bit.

@RedDragon: Ah, yeah that makes it a lot easier to read. Just try to keep that in mind for future posts heh, the easier you make it for us the better we can help ya.

Speaking of the MTHEL-FE, now that I've gotten a full night sleep the idea of Rex's laser being 100mW... doesn't make a lot of sense. 100mW is a LOT of power and the lasers rather... questionable... location (seriously, it's pretty much Rex's robo-youknowwhats heh) seems to imply it's main purpose is to be a defensive weapon soooo.... it makes little sense to place such a super powered laser in a location where it's mainly going to be shooting at lightly armored targets and not be able to take advantage of it's huge range (in all honesty they should of put a 50 cal there and put the laser ontop of Rex so it could shoot down missiles....) so I'm thinking it should probably be down graded to only 100 *Kilowatts* instead of *Megawatts*. That would drop damage down to 4d5(2), range down to 16,000/48,000, weight down to a far more reasonable 300lbs without needing to use the super science option, drop ST to 41M, cost to $150,000 and power per shot down to 322kW.

I'm also having a hard time seeing Rex being able to mount a 700mm cannon given that Rex is only about 15 meters tall and it seems the 700mm thing only comes from secondary sources that stat it somehow shoots a airforce Advanced Cruise Missile... While I don't have the tools (or patience heh) to do an accurate scaling of the railgun I doubt it's much more then 200mm and in that case I'd just say use the 160mm railgun stated in More Ultra Guns and Heavy Weapons found in Pyramid 3/37.

Also lastly nuke damage is a bit off in RAW GURPS since... well... explosive damage is a bit off (originally HP were scaled differently when they were writing 4th edition and explosive damage was scaled to that, they then changed the scaling but didn't have the time to go back and change the explosive damage so they just stuck with it). As it stands explosives scale with the square root of the explosives weight while the should really scale with the cube root so if it matters I can rescale the nuke damage for ya.

I created a 100 MW laser, then realized it was ludicrously overpowered (I think it had a Max range of 1,000,000 or something), so I just used the Med. Laser Cannon.

The MG Wiki says it fires AGM-129 ACM missiles. According to Wikipedia, the thing is 2 and a half feet wide. I can't really see how else to stat it up, so suggestions and ideas are welcome. I created this thread just so that people can have workable, detailed stuff for Metal Gear campaigns, so I don't need the fixes for a campaign of my own (I'm not planning on running one, at least for a while), but factual stats are appreciated for posterity.

As for the nuke damage, is the 4e revised explosive damage the same as the 3e explosive damage? This stat block is for 3rd edition, so if the damage stated in GURPS Vehicles pp.108-109 is accurate for 3e, I don't think I'll change it.

I think next on the list is a 3e Metal Gear RAY (not sure how to do the water cutter though... Liquid Projector or Laser w/ some rule changes), then maybe 3e & 4e versions of Solid Snake (probably gonna be 450+ points for the first 2 MG & MGS games [lighter and lacquer spray flamethrower implies he has Gadgeteer] , and significantly lower for MGS4, as it seemed a bit less cinematic to me.)
