From the announcement:
More Modular Guard bits! This month sees two new arm sets, the Victorian Rifle Arms and the Dress Uniform Rifle Arms. Also I am thrilled to present a new set of Pith helmet heads, this includes 10 individual trooper heads one officer head and a spare helmet.
A new special weapon the 'fusion gun' is also released this week as well as some handy grenade sprues, officer arms and some seated conscript legs.
