Hi,

The Salamander Tech-marine in my kill-team just asked for a Thunderfire cannon ...

i sat down and came up with the following stats and would like to hear your comments:

Thunderfire Cannon
Type: Self-propelled Artillery                               Tactical Speed: 6m
Cruising Speed: 9kp/h                                         Manoeuvrability: +0
Structural Integrity: 10                                           Size: Hulking
Armour: Front: 14; Side: 14: Rear: 14                Carry Capacity: None
Crew: Remote Controlled                                   Renown: Distinguished (will onyl be issued to Tech-marines)
Weapon:
Thunderfire Cannon
Range 250                Heavy -/-/4             Dmg: see ammunition               36(internal)          Reload 6 Full

The Ammunition can be set to 3 different explosion Types:

Airburst                                           3d10+6                  pen 4                                      Blast (6) ;ignores cover

Surface Detonation                      4d10+6                  pen 8                                      Blast (4):

Subteranean Blast                       2d10+6                  pen 2                                      Blast (2): Double dmg and penetration vs. buildings , 

nice seem well thought out and will be handy vs hordes and nids :)

 It's good.

The only thing I find odd is the large clip, going from the model there really isn't enough space for 36 shells.

I'd drop the clip to 4 or 8 and the reload to 1full or 2full. It just seems more reasonable.

If I remember correctly, the Thunderfire Cannon in the tabletop has something like twice the range of a Heavy Bolter, so the 250m range might seem a little short. Also, a Space Marine is already Hulking in size, so I would assume the TFC to be at least one size bigger.

Yes to both of the above, it's bigger than hulking obviously, can't comment on the range from here.

It wouldn't surprise me if it needs an MIU (connected to a remote, or even a cable) to control.

It looks like it might need need to be reloaded for each shot, you could give it a rule about being reload 1full if you use a utility mechandrite and pre-clipped in 4's like the model has. It certainly doesn't look like it has a massive internal magazine and a ammo selector.

Also carrying ammo is going to be an issue, on the table top there could a truck or rhino parked next to it full of ammo, for the table top you could carry some yourself and put some on the weapon or have servitors carry the load for you.

 If it's supposed to be arty, isn't the range way too short? Does it fire indirectly? Even a light mortar has more range, so don't feel constrained by the tabletop rules. 

I'd double the range. At least.

Thanks all for ypur replays

Increased Size by one category; range increase proportionlay to that of the standart bolter; dramaticly reduced clip-size: added rules for the ammo-clips;

Added special rules for the controll-range and the MIU

Thunderfire Cannon
Type: Self-propelled Artillery                                    Tactical Speed: 6m
Cruising Speed: 9kp/h                                              Manoeuvrability: +0
Structural Integrity: 10                                               Size: Enormous
Armour: Front: 14; Side: 14: Rear: 14                    Carry Capacity: None
Crew: Remote Controlled                                       Renown: Distinguished (will only be issued to Tech-marines)

Special: The Remote controller needs to be within 10 meter of the cannon to move and fire it; If the controller doesn`t have an MIU he takes a -20 to attack; The Cannon can move and fire without penalty

Weapon:
Thunderfire Cannon

Range: 500m    Heavy -/-/4 Dmg: see ammunition     8(internal)   Reload 2 Full (1Full if you have the ammuntion pre-clipped [1 Full to pre-clip})

The Ammunition can be set to 3 different explosion Types:

Airburst                                  3d10+6                       pen 4                                        Blast (6) ;ignores cover

Thanks for the fantastic work chap.

Do you mind if I use this rules for my campaign as well and also: do you have any idea about how many requisition points this thing should cost?

Knightmare said:

Wouldn't mind in the least, i'd even would feel a bit flattered :p

About the point cost: I have no idea and i couldnt test the cannon in game, because my PRg party fell apart. :(

At hich cost did you hand the cannon out and have you tested it already?

Shouldn't it be like any other vehicle and have it only possible if the Kill-Team leader req's it?

In this case, if the tech marine is the kill-team leader and is of Distinguished or higher level, wouldn't it be available for free as long as it's the only craft they ask for?

Hey Knightmare, awesome work man!

I'll use your stats on my campaign too.

Thanx a lot.

Changing the subject, I tried to search the stats of the Hellbrute without a success, does any one have a clue about it? 

Best wishes from Brazil!
