Roma II: Total War Camera Mod
This is a simple mod that edits the land battle camera, sea battle camera, campaign camera, and unit camera. It increases the max and min zoom distance in the battle and campaign maps. It also lowers the unit camera in the mix position and lets you raise it much more.
With this mod you are now able to fully manuver the cinematic unit camera. It can zoom anywhere from ground level to about 50 ft, and it can be full rotated.
