The Core Set includes:

39 unpainted and highly detailed miniatures give you the building blocks you need to begin assembling your Galactic Republic or Separatist Alliance armies.
Obi-Wan Kenobi and General Grievous each pose with light sabres at the ready, prepared to lead their troops into battle and show off their skills in combat. Both these miniatures are exclusive to the Clone Wars Core Set.
Two squads of Phase I Clone Troops enter the fight to preserve the Republic. Five carry the DC-15A blaster rifle while two heavy weapons specialists add extra firepower with a Z-6 rotary blaster cannon and a DC-15 blaster rifle modified to fire from long range.
A BARC Speeder miniature gives your Clone Troopers some much-needed speed as they look to out-maneuver the Separatist's battle droids and can be assembled with or without its sidecar. Those who include the sidecar can further customise their speeder with a twin laser gunner, an RPS-6 gunner, or an ion gunner.
Two squads of B1 Battle Droids are ready to crush any resistance with sheer weight of numbers. Seven are armed with E-5 blaster rifles, while two heavy weapons specialists bring either an E-5C blaster rifle or an E-60R missile launcher.
One unit of two Droidekas is ready to speed into battle in wheel mode. Once there, the wheel mode miniatures can be replaced by two Droideka miniatures ready to lay down heavy fire on targets the B1 Battle Droids cannot take care of.

Note:

While the original Legion figures were "fixed pose" and made of a few pieces, the Clone War separatist figures are supplied on sprues (like the old airfix models, or like Games Workshops models) with more individual parts. This allows more flexibility in creating individual and more dynamic poses, rather than having an army of identical figures, and can make painting easier. But this does mean they are more fiddly and time consuming to put together. So please bear that in mind - Especially if you're thinking of building a massive separatist droid army. The clone figures are more similar to the old style legion figures (not on sprues, less parts).
