Fire Power R' Us: weapons for d20 modern and variant settings

[LonewolfSojourner1983]

Well that's more or less all I have for now, I have some stuff I posted to other message boards left but, most of that would need context, so it will take longer to post. Any comments so far?

[LonewolfSojourner1983]

I'd like to present the Blitzkrieg (yes it was built in Germany)
Blitzkrieg PL 7

The Blitzkrieg (Lightning war) is a heavy weapons platform designed to serve on the battle field in a similar role to tanks, while the Jetpack was added to allow the Blitzkrieg to rise above the battle field and rain destruction on opposing forces and engage low flying aircraft.

My attempt to convert the antimatter rifle from the dm's guide to modern.
 PL7.
Name*Anti Matter Rifle. Damage6d8.Crit:20x2. Damage type: Energy. Range Increment:120ft. Rate of Fire: Single. Weight:10lb. Size: Large. Purchase dc:23. Restriction: Restricted(+2)
Antimatter power cell Purchase dc 8 Weight 1lb
*requires the Personal firearms Proficiency feat to use without penalty
Antimatter rifles are heavy weapons employed to destroy light vehicles
and eliminate heavy infantry units. This weapon uses a special power cell that is depleted after 2 shots.

Cause really the deep space thrusters from future tech sucked
The Mecha Induction Engine(PL7)
Like the Deep space thrusters these engines are mostly intended for mecha that spend a lot of time in space, though they function in an atmosphere.  In space they provide a tactical speed of 2,000ft (4 squares), in an atmosphere they provide a fly speed of 500ft with average maneuverability.  Do to the massive power requirements of this engine the mecha must have non-standard power core, while the slots it occupies do not have to come from the core it must be present.  While the engine it self requires no fuel, it does require a special fuse/converter to keep it running. this fused must be replaced after every 5 space flights or after every 10 adventures.  The engine comes in to versions the standard and the long range.  The long range does every thing that the standard does plus grants 5x speed of light travel, light speed travel requires a specialized fuse that must be replaced after each ftl trip, however the trip does not count against the life of the standard fuses.
 Slots: 4 must be legs back or belt.
Activation: Free Action
Range: Personal
Target: You
Duration: Personal
Saving Throw: None
Purchase DC: Standard; 15+1/2 Base Mecha purchase dc. Long Range; 20+1/2 Mecha Purchase dc. Standard fuse: 17 per pack of 6. FTL fuses: 20 per pack of 2.

The XM-1 is widely considered a failed project, only 12 were ever built with 4 confirmed rogues (XM-1's that no longer follow there old programing), rogues have AL:None but, are otherwise identical to the other XM-1's, with one of those rogues developing a distinct personality (See below), and 3 others missing and presumed rogue.  XM-1's resemble giant mutant crab aliens bristling with weapons.  Each XM-1 is self sufficient enough maintain it's own recharge cycle, refuel it's own flame throwers, and make its own stakes for re arming the stake cannons. 
Stake Cannon: A specialized Revolver cannon with a rate of fire around 650 rounds a minute.  It relies on a special compressed air tank.  The tank holds enough air for 1,000 shots and can hook up 2 cannons, after firing 1,000 rounds it must recharge, a process that takes 2 hours.
Stake Cannon (Cannon): Dmg 2d8 Dmg type Piercing. Crit: 20. Range Increment 200ft. RoF: S,A. Magazine; 500(int), Size; huge. wgt;90lb. Purchase DC: 23. Res: Mil+3.

Zeke: While Zeke used to be like all the other XM-1's, he has developed a sort of conscious.  It happened when after pursuing a pack of Vampires across the boarder into Mexico, he caught up with and killed the vampires but, was then racked with guilt upon learning that they were protecting  a village.  Sense then he has been protecting the village. Zeke has an AL: of Village but, is otherwise identical to his brothers.

RPG-S (PL5) Dmg: 4d8. Crit: 20. Dmg type: Ballistic. Range Increment:100ft. RoF: Single. Magazine: 1(int). Wgt:8lb. SZ: L. Purchase DC:17 Res: Mil+3. Ref:15 Burst:10ft.

this one's kinda dated now
Here is my take on the Thor as of the most recent Demo.

The Thor* (Starcraft 2)
Colossal Walking Fortress Mecha
Size: Colossal(-8)        Bonus HP: 800
Superstructure: Duralloy. Hardness:15
Armor: AlumiSteel.         Defense:+5
Penalty: -6                    Reach: 15ft
Strength:+32.                   Dexterity: -4
Speed: 55feet.            Purchase DC:65($652,437,550)
Equipment Package
Cockpit(Belt), Co-Pilot Cockpit x2 (Torso x4, Back x2),  Oracle Mk IV Targeting System(Helmet), Class III Sensor System (Helmet), Comm. System(No Slot),  Space skin(Left Leg), Life Support(72 Hours)(Right leg, Cranium, Visor), 2 hand Replacements (1 Left, 1Right), 2 P-7 Rail guns(W/ Hand Replacements) w/24 rounds each(Left hand, Right hand, Left and Right hand Replacement, Left leg x2, Right leg, Right arm), Heavy Artillery System w/24 shots(Shoulders, Left arm x2, Right arm, Right leg, Boots, Back).
 
Heavy Artillery System(PL7)
The Heavy Artillery System or HAS is as brilliant as it is simple.  The weapon relies on four cannons slaved together to fire in sequence.  The HAS is expensive and bulky, it is usually limited to Siege or Colossal Mecha and only benefits from a Mecha’s targeting computer if the target would be considered Gargantuan or Colossal in Character scale.
Slots: 6 must be, Arms, Shoulders, or back.  Plus 1 slot per extra 4 rounds. Activation: Full Round, Duration: instant. Target: Single Target within 3,000 ft. Save: No.
Damage:10d12. Crit: 20. Damage Type: Ballistic. Range Increment: 300ft. RoF: S. Magazine: 8(int) (2 per Cannon). Size: Gargantuan. Weight: 380lb. Purchase DC: 42. (18 per extra 4 shell pack). Restriction: Illegal +4. 
* would be more like the Odin from the finished game.

Somethings I made for the Core thread from the old WotC boards
Service Rifle (PL5)
   Yes it is Battle rifle inspired.
R-25 “Brush Rifle”(.30-30) Dmg: 2d8. Crit:20. Dmg type: Ballistic. Range Increment: 50ft. RoF: S, 3round Burst(-2 Attack, +2d8).Mag: 25(box). Wgt: 6lb. SZ: L. Purchase DC: 17. Res: Res+2.
   The R-25 is a compact bull pup assault rifle mainly meant for arming rear echelon units.  .30-30 was chosen because it is common and relatively cheap. The weapon’s design includes both red dot optic, and iron sights and a forward grip.  The R-25 is a rugged assault rifle that can only become un reliable due to damage or neglect(See Unreliable rules in Weapon‘s Locker).     

SMG(PL5)
UPW 40-40(.40S&W) Dmg: 2d6. Crit:20. Dmg type: Ballistic. Range Increment: 50ft. RoF: S,A .Mag: 40(box). Wgt: 6lb. SZ: L. Purchase DC: 17. Res: Res+2.
The UPW (Universal Police Weapon) is heavy SMG designed to put heavy fire power in the hands of SWAT and rear echelon personnel for a relatively low price.  By SMG standards it has a low rate of fire (500 rounds a minute), it also has a simple adjustable stock (read a padded butt-plate and two metal strips).

Side Arm (PL6)
Thunder Ball(.44magnum Incendiary)Dmg: 2d8+2d6. Crit:20. Dmg type: Ballistic+Fire. Range Increment: 40ft. RoF: S .Mag: 15(box). Wgt: 5lb. SZ: M. Purchase DC: 18. Res: Res+2.

--Under barrel 12gaugeDmg: varies (see below). Crit:20. Dmg type: Varies (see below). Range Increment: 20ft. RoF: Single. Mag: 4(box).
Ammo types: Buckshot 4d4 Ballistic, -1damage per round.  Slug -2Atk 2d10 Ballistic. Grenade (Frag) 3d6 slashing 5foot burst ref 15 for half damage.  Grenade (Incendiary) 2d8 Fire 5 foot burst Ref 15 for half damage, standard rules for catching fire.
   The M 36 Commando rifle is a compact bull pup weapon designed to arm special forces units. Like the R-25 it has both Iron sights and a red dot optic sight, and it can also be fitted with the M-25’s scope for long range combat.   

Mangalore and there Gear.
The Mangalore are large bulky humanoids with reputation for cruelty, and a complete lack of initiative.

Monstrous Humanoid

A couple gadgets for a super hero thread
Not sure about the suit but here's my take on the grapple gun
Grapple Firing Crossbow(UA) Reduced Weight(8lb), Motorized Winch(speed ¼, ½, ¾ or 1 range increment per round max load 250lb/100kg) +6 Purchase DC.
Final Result: Super hero Grappling gun(Archaic Weapons proficiency) Dmg 1d3(piercing) No Crit. Range Increment:120ft* Mag 1 RoF1 Reload Full round. Weight8lb SZ: Medium. Purchase DC:16. Res: none.
 *Maximum range 360ft
success or failure based on attack Natural 1, Rope breaks, bolt goes off into the sky some place, normal miss does not strike anything it can grab onto cable can be retracted( at speeds listed above) for another try. Hit by 5 or less unsafe purchase Str check DC17 to remove for reset, or attempt to climb will come out after you have traveled 2d10 feet. succeeds by 6 or more, no worries.

Wrist Watch two-way radio.
As the name suggest a watch sized walkie talkie (professional model) that also features a working watch, no weight worth noting Purchase DC:21

Ok that's my entire back log.

Hmm, nice stuff, though theres sheer volume and the lack of formatting makes it a bit tricky to wade through.

[LonewolfSojourner1983]

As this is the Homebrew section, I feel I should post some house rules I try to work into my modern campaigns.

One handing/ Dual wielding large weapons: one handing incurs a penalty based on the dice used for the weapon 2d4 (-1), 2d6 (-2), 2d8 (-3), 2d10 (-4), 2d12 is of course impossible. Treat as a one hand weapon for TWF purposes with the dice based penalty stacking.

Small creatures with Medium weapons
first off large weapons: Small creatures can't dual wield not even the 2d4 ones.
Medium Weapons: 2d4 weapons impose a -2 penalty, 2d6 a-3 penalty and 2d8 a -4 penalty,  2d10 weapons with 1 or 2 round magazines -4, 2d10 weapons with 3 or more round magazines cannot be dual wielded, as with the medium creature wielding large weapons for TWF purposes count as two one hand weapons one handing penalties stack. 

Here are a couple that I have adapted for my campaigns based on comments I have seen on other post
Small Creatures take no size related penalties for wielding large Firearms that deal 2d4 or less damage, also applies to Simple large ranged weapons that deal 1d8 or less.
Large Creatures treat Large automatic weapons that deal 2d8 as machine pistols 2d10 large automatics add an additional -1 penalty for TWF and one handed firing.

Double tap: +1/2 the damage dice(Rounded down)of the weapon in question, can be used with Mecha and star ship weapons.

Burst Fire:+the damage dice of the weapon in question, again can apply to Mecha and Space craft.

2and 3 round burst settings: -4attack with out burst fire -2 with burst fire.

Undead Mas Saves: All undead have a modified Mas system. This score is equal to their Wisdom score +1 per four Hit dice, if the undead takes damage that meats or exceeds this score they must make a DC15 (or what ever your own rules dictate) Will save or instantly perish (This rule does not apply to incorporeal Undead). This rule is meant to represent a trapped souls, willingness to cling to any form of existence.

Future
Star ship cores: This rule is based on the alternate star ship power core rules listed in future. Non standard power cores provide a number of misc. extra equipment slots, equal to half their Purchase DC modifier (The Listed modifiers are +0 [standard core no bonus], +4 [2 bonus slots] or +8 [4 bonus slots]).
FTL drives, and Afterburners: First Afterburners(future tech) do not count against a ship's engines can only have one. FTL/Time/Dimension Drives also do not count against a ship's engine total: Huge or Smaller Ultra light: None, Gargantuan or Colossal Ultra light/Light: 1, Medium Weight/Heavy: up to 2, Super heavy: up to 3.

Mecha combat:  The RAW allows for use of one Mecha weapon at a time (I think TWF is allowed).  With this rule a mecha pilot can fire each active weapon on his or her Mech.  This is like an animal with bite and claw attacks (First attack primary, all others secondary -5 attack).  A weapon must be fired within 4 rounds of activation or you must spend another action to activate it again (Activation is a Free Action unless the weapon states otherwise).

Teleportation systems and Star ships
 These systems are detailed on page 103 of d20F.
Ship Size/Number of Transport systems
Gargantuan or smaller Ultra light: 1 most often incorporated into the cockpit.
Colossal Ultra light: 2, Light: 3, Medium Weight: 4, Heavy: 5, Super Heavy: 6

Transport Booths and ships comm. systems: Because a ship has two (or three) communications systems a ship can purchase Transport booths for the base purchase DC, however a ship that does this can never run more booths at any one time than they have comm. systems, regardless of how many booths have been purchased, and can not use comm. systems engaged in the transfer of personnel to communicate with other ships or people.  On the other hand transmitters purchased with the booths are dedicated and can not be used for communications purposes.

When it comes to adding more guns to a ship I have a couple of house rules:
 Rule 1 the double weapon template it add one of the following and adjust the Purchase DC by the listed amount: Improved Rate of Fire: Semi auto PDC+2, Full  auto PDC+3, +1 Attack PDC+2, Improve Critical threat range 1 step PDC+3, add 3 dice to the weapon's Damage PDC+3.  For balance sake, while double weapons can be fire-linked or placed in batteries, they must be placed into batteries or fire linked groups of the same type (Meaning you can't take a full auto double Rail cannon and place it in with a +3 dice Rail Cannon.) also the bonus for fire linking is based on the base weapon's damage. the improved critical threat and +1 Attack bonus stack with the bonuses for being in a battery but not with each other (Two +1 Double Needle Drivers in a battery would have a total bonus of +2 not +3 for example, and a pair of improved Crit Dual Neutron guns fire linked together would still only be Crit 19-20). This template only applies to cannon type weapons

Star ship Weapon Batteries: I track how many slots they take up based on ship size: Medium-Weight; 1 slot for the first 2 weapons in the battery +1 for every additional weapon.
Heavy: 1 slot for the first 3 weapons in the battery +1 for each additional weapon.
Super-Heavy; 1 slot for first 4 weapons, 2 slots for a five weapon battery.

The Pulse Rifle: change damage type to Energy, +10feet to the Range Increment, add a 3 round burst setting (I'm pretty sure that burst part I got from Aussie Gamer)

Cybernetics: Cybernetics with specified positions on the recipient's body (Head, Arm, torso, ect.) do not count against their limit for cybernetic components, only cybernetics that has a listing of none for location counts, cybernetics with a specific location do however count against the max number of cybernetics a given body part can hold.

Hmm, nice stuff, though theres sheer volume and the lack of formatting makes it a bit tricky to wade through.

Definitely.  Formatting and (nested) spoilering would be a HUGE help.
