Guidance Points

All of these Undead are within Kingsley Warlock's Control Zone

Controllers in Black Sun Parties have Guidance Points which allow them to do a couple of things:

• Maintain or regain Control of Uncontrollable units within their Control Zone (see below) 
• Recover extra Action Points for Undead units, subject to those units' limits (Influence)

Undead units run the risk of going out of control (the Uncontrollable rule). For many Undead, the chance to become Uncontrollable is quite high. Uncontrollable units pose a risk to any non-Undead units nearby, friend or foe, activating similarly to Berserk models.

The key then is striking a  balance between the number of Controllers and Undead in your Party. So far the typical number of Guidance Points per Controller is 2, with a couple of exceptions (Promethea and Luther Delacroix both have higher than usual Guidance Points values).

So while Undead are relatively cheap units to fill out a Party, one vital element looks to me to be in making sure your Party has enough Guidance Points available, or off-setting Uncontrollable where possible (Styx can effectively avoid Uncontrollable for example; Type-005's and Type-020's have limited upgrades that allow a single choice of those units to ignore Uncontrollable). Of course, it also means clustering units to an extent to ensure coverage of Guidance Points since Control Zones are typically 8 inches from a model.

Figure 1: Kingsley Warlock has 2 Guidance Points; when choosing the Party, if one of the Type-005's is upgraded to a Type-006: Commander, then he could use those Guidance Points to ensure the Type-020: Verrier does not become Uncontrollable, leaving one Guidance Point to boost AP.

If, when choosing the Party, the Type-020: Verrier is upgraded to a Type-021: Queen, then the Type-005's would ignore Uncontrollable as would Styx, as they would be of lower Level. This would allow Kingsley Warlock to use 2 Guidance Points to boost the AP of Undead (basically an extra AP for 2 units).

Styx cannot benefit from extra AP from Kingsley Warlock as only Promethea may spend Guidance Points on Styx. With his Uncontrollable value of 1+, he should always pass the roll unless a modifier applies.
