For one to rule, the other must die. 312 AD is a year of horrific and brutal warfare. Constantine's northern army is a small force, plagued by religious rivalries, but seemingly unstoppable as they invade Maxentius' Italian heartlands. These relentless clashes, incidents of treachery and twists of fortune see Maxentius' armies driven back to Rome.

When the two forces clash in the Battle of the Milvian Bridge, there are factors at work beyond their control and soon they are left with carnage.

There is only one way Constantine and Maxentius' rivalry will end. With one on a bloodied sword and the other the sole ruler of Rome . . .
