A decent sized update hit the FiveCore skirmish rules today (the 3rd edition rules to be exact, the sets contained in the retro collection won't see updates, that's why they are retro and cheap)
1: The Move and Sprint benefits are now the same thing.
A figure with +2 Move (for example) moves 2" faster and if they roll a 1 or 2 when Dashing, adds +1 to the Dash distance.
2: Firing at a Clear Target (in the open within 12" is now +1 Kill die, instead of rerolling a die.
3: A new optional Man to Man mode is added.
In this mode, you take it in turns to roll 2 Action Dice (typically) and apply them to 2 figures of your choice, until everyone has acted.
Basically a more conventional turn sequence that still uses the Action Die mechanic.
Totes optional but a lot of fun.
4: Squad Morale is now a thing.
Once a squad drops to 5 members or less, they have to test morale to see if they bail out.
Its very easy to use.
THe old High Spirits/Despair rule (which frankly was always a patch) is gone, instead things that affected that now affect the new Squad Morale instead.
5: The "Scared" morale effect is gone.
Rolling a 1 on the Shock dice now forces the target to Flinch (hide behind cover or back up 3" towards cover) but has no lasting effect.
This is sort of drastic and does reduce suppression fire a little bit, but I find that it plays far better and removes one of the markers cluttering up the table.
Go ahead and download your files again from the wargame vault, the update is free for everyone who owns the game.
