Here's the miniatures for the scenario all lined up quite in quite a friendly manner, blissfully unaware of the carnage yet to come.
The civilians who built their reactor on top of an alien burial ground. Although some of them carry weapons they will be ineffective in combat.
The Bugs. Justifiably upset with the colonists, they seek to gain their revenge by taking out a no win, no fee legal damages claim in the local courts. Failing a successful result they will resort to eating the colonists.
Eight groups of 5 aliens each, armed
The King and Queen, not sure which is which. These are old Citidal miniatures.
The legionnaires. Three squads of bad ass trooper types. All they are missing is a nuke to take off and bomb the aliens with from orbit. Which is a shame as they are probably going to need one.
The vehicle is crewed with a spare half man (Khurasan again), and a crouching heavy machine gunner (Oddzial Osmy's New Vistula Legion).
Next task, make up a few more road sections to cover the length and width of the 6' x 4' table. The colonists buildings may very well start out as ruins - building on alien burial grounds is terrible for subsidence.
Easter Bank Holiday Carnage Ahoy!!!
