What power armor propulsion works under water? Also, do MD lasers work at all under water? Any official rules on such?

Rifts WB-7 and sourcebook-4 mention blue-green lasers for underwater use.....plus underwater power armor just mentions thrusters for underwater movement

Thanks. Here's another question, how does rain and fog effect MD laser weapons? I would think they could burn through a lot of it...

No official ruling I'm aware of.

The only way Rain and fog affect MD Energy Weapons is the targeting issues that they impose.

If you look at the old Nuke Testing films you will see the clouds in the area disappear, turn back into vapor, as the air they are in are heated up by the blast. The same thing happens, on a smaller scale, with MD energy weapons.

Rain and fog have no effect on energy weapons.

Alright, so back to lasers underwater again. I've got a standard Wilks MD laser pistol shooting through (SDC?) water. I'm thinking it could shoot a short ways, maybe 10% normal range? Or would it just disperse the heat way too quickly and make it effectively non-functional/useless (just vaporizing some water point blank) submerged?

I know they sell laser that are made for underwater. I also think there is a conversion kit you could get for you gun. As for the reductions for using a standard laser underwater I know my GM had range and damage reduction penalties, not sure if there were official or something he house ruled.

i just take the penalties for using a Blue-green laser on the land and apply those to land lasers used underwater.

What are they? Where I can find them? Thanks!

Fog can easily impair vision (as can rain). So its likely two characters running around in heavy fog or heavy rain would count as 'Shooting Wild.'
This translates as a -6 to strike (remember, a roll of 8 or lower misses with ranged attacks!). So sheathing one's self in Fog (as per the Water Warlock spells) or a Sandstorm (as per the Earth Warlock) is a very effective defensive tactic.

There are complete (optional) rules for underwater combat in Lemuria.

Rifts Worldbook 32: Lemuria - Underwater Combat Penalties for Surface People, page 59 wrote:Nonaquatic races like humans suffer penalties of -2 on initiative and Perception Rolls and -2 to strike, dodge or parry when fighting in close combat underwater. Accuracy with ranged weapons is unchanged.
Amphibious races like Lemurians, Splugorth Slavers, the Naut Y’ll and Amphibs are unaffected, and fight equally well on land or underwater.

I will not post all the specifics but this should help:

Thanks Akashic! I should get Lemuria then!

Glad I could be of help.

indeed, thank you. I even have Lemuria and must have blown passed that section somehow when I read it.

i am pretty sure contragravity flight systems function normally underwater and the penalty for lasers doesnt take effect until a depth of 200 feet i believe.
