There's several ideas that have been thrown out over the years on the board.
-Chroma in the
Total War scenarios book(s) had options in several ideas of Night Fighting or reduced visibility environments. I don't have the specific ones in my memory but give them a read.
-Dooglebug had wayyyyy back suggested the following
Quote:
normal LOS limited to 30cm except for units with night vision (eg. all SM units, flyers and Titans/Gargants) it could also be available as an upgrade to certain units (eg. stromtroopers, armoured companies).
normal units units with night vision
0-30cm -1 to hit normal shooting
30cm+ no shooting -1 to hit
This does not apply to shooting against warmachines as they would be a bit hard to miss still.
Bombardments and other indirect fire are unafected. Illumination parachute flares could be fired instead of a bombardment or dropped by flyers to allow other units to shoot at one enemy formation as normal the effect lasting for the rest of the turn.
I would also suggest some sort of morale effect. Additional -1 to initiative for units regrouping/rallying in the end phase unless there is a freindly unbroken formation within 30cm?
-IIRC, Black Legion had some ideas about environmental conditions on th battlefield. Homie was anything if not prolfic so digging through the 600 pages of posts isn't in the cards at the moment.
-I've produced some rules for Epic: Battle Tactics that I'm happy to share with you. They use the name, "fighting at night" but only as being representative of reduced visibility rules, irrespective of actual cause (a very Epic abstraction).
Quote:
4.2 Fighting at Night
Not all battles occur during broad daylight in the middle of the day (some estimations account for more than 1/3rd of battles fought occurred during less than full visibility). The Night Fighting rules account for any scenario where visibility is not clear and LOS affecting conditions exist, not just night conditions (perhaps the world is shrouded in thick volcanic clouds obscuring daylight, or a forgeworld / hive world during an ash storm).
Units maintain their usual ZoC though in all cases FF range will be reduced to 10cm representing the ability of units to close under the adverse conditions before engaging the enemy. Shooting attacks by weapons with less than 10cm range are unaffected. Weapons up to 15cm or less are reduced to 10cm. All other weapons reduced by at least 25% range or 30cm, whichever value is less.
I'm stealing your idea about WE however!
