As for zulus i need to look at all my books, i also have the zombie one too, there is a couple of rules about reactions, and all units with so many inches react as well, also look at my starship trooper files..
Arachnids Special Reactions:
Alarm Screech: As a Reaction, an Arachnid unit can call for other Arachnids. Any Arachnid unit (regardless of actual species) within 6” of a screeching unit may take an immediate Move action – this counts as making a Reaction. The screeching bugs themselves can also take a Move action by using this Reaction.
Countercharge: An Arachnid unit may take a Charge action as a Reaction. If enemy models are engaged in close combat with this Charge action, they must include the models that triggered the Reaction.
Rename them (obviously) but these seem fairly appropriate for a mob of assegai-wielding zulus.
'Area Suppression' - in order to increase the amount of suppression without resorting to unique special rules (too much) you need to fling a lot of dice across a large area.
1) A 6" fire zone (or larger! 'volley fire' 8" fire zone?)
2) Relatively small unit sizes for the Impis (a mass of 20-30 troops is very hard to suppress if just clipped by a fire zone on 5-6 models...)
3) Lots of dice that are less likely to score hit and kill results (so 2 or 3 attack dice at D6-1 or D6-2 rather than 1 at D6).
You end up with lots of shots that don't score a hit but still count towards suppression - hence the number of times that a unit under fire loses actions rather than being slaughtered in droves (BF:Evo rules are really not nice for unarmoured light infantry in the open!) goes up, and if there's two or even three times the number of dice involved, units caught under the fire zone other than the main target still get suppressed.
Oddly reversed as it sounds, making the British fewer, larger formations and the Zulus masses of small formations (possibly forced to keep in coherency with one another to benefit from the 'alarm screech') might work well.
