Undersea Campaigns

[Undersea Campaigns]

Adeptus-b: Heavy gravity does sound pretty good, that ought to simulate underwater movements pretty well. Also, i imagine that there would have been a sub-tank that Land discovered, but he called it a Land Submarine, which ended up confusing the mechanicus so much that they never bothered making any.

 

Calgor Grim: That submersible rule sounds great! I reckon i might get the guys to kinda give all this stuff kindof a test run in the hunting grounds or something, have them hunt an alien squid/whale or something Ahab style.

 

Though one thing i think still needs to be considered is the effects of depth pressure. I imagine that power armour could take a fair amount of pressure before it starts being compromised, but that would probably have the effect of also making the armour weaker/more vulnerable. So it'd something like for every 25m (or whatever the more realistic number would be) deep they go down they loose an AP on their suit, and if it goes down to 0 then the armour and whatever is inside it is crushed.

Yeah i imagine that a land raider should be able to withstand a fair amount of pressure, or at least capable of being modified to be even stronger against that. Maybe by welding shut the from ramp and locking the side ones, and hell maybe even a periscope modification for firing the pintle mounted weapon. And if they're going in a land raider then it's weight pretty much means that it'll be going across the ocean floor, so i imagine that its shape wouldn't matter as much and more than it would when outside of the water. The only problem then is the weapon loadout.
 

Yeah i thought the same, there should be some kind of submarine tank thingy in 40k, but it's just never been mentioned in cannon yet. Modifying something like a valkyrie or stormraven could be a route, but actually i might, if they want to use an actual sub-rank rather than a land raider, just modify a couple of stormraven stats and call it a sub-tank instead. Like instead of the flyer trait i just call that "Submarine" instead. That might be an interesting idea, thanks for that.

 

I actually imagine that lascannons, missiles (renamed as torpedoes) and melta weapons should work underwater, though naturally energy weapons would suffer a penalty in distance, but i'm not really sure about bolt and projectile weapons. In real world physics bullets and such pretty much don't work underwater, their thrust is designed to propel them through air rather than water, which is far more dense. Though, as you said, there probably could be some kind of aquatically modified bolt round to compensate.

Well the world in question would have originally been an agri world, with the sea life being harvested as a food source on a massive scale. There would have been cities/spaceports on each of the worlds poles that're built ontop of the ice there and most of the actual harvest would have been done of massive, mobile factory ships. So the worlds intrinsic value would have been as a food source.

 

Though yeah, i suppose it is rather flimsy.

 

Perhaps instead of an entire campaign set on an ocean world i'd just have it on a regular planet and throw in an undersea mission sometime.

Hi there, just started out as a DW GM and further down the line i was planning on maybe having an anti-tyranid campaign take place on an ocean world, purely because i think that that would open up an interesting new style of warfare for the group as they fight off a bunch of kaiju amphibious 'nids. The problem is that i'm unsure how.

 

Having them on a warship alot of time would make sense, but for some missions i want to be able to deploy them down beneath the surface in, preferably, some kind of submarine style land raider.

 

 

I was wondering, does anyone know of any actual canon seafaring/submersible vessels or have any experience playing a game on an ocean world? And if there aren't any canon boats then what kind of rules would be recommended to just make up some?

 

I've got tome of blood so i was already thinking of reworking the sea-skimmer rules from that (deathwatch marines on jet-skis, the truly unstoppable force!), but for bigger boats and submersibles i'm somewhat at a loss for those.
