Tin Soldiers: Julius Caesar brings a completely new 3D engine into the battle, allowing users to zoom in, out, and rotate the map for a better view of the battlefield. The artwork overhaul features over 100 different replicas of hand-painted miniatures, including the fearsome legions of Caesar himself. On the inside of the game the AI has been overhauled as well to support a variety of battle formations while the legions of Caesar have been expanded from the normal block of four units to a more powerful block of six. This allows you to replicate the power and strength the Roman legions possessed.

The campaign mode features two distinct campaigns that no longer occur in linear order. You must defeat the Gaelic campaign and the final showdown against the combined forces of Gaul at Alesia and then proceed to the Roman civil war, where you will conquer Rome itself. By keeping many of the aspects that made Tin Soldiers: Alexander the Great popular and improving it in many areas; Tin Soldiers: Julius Caesar will be appealing to both existing fans and newcomers alike.
