Note: This procedure requires editing a game file; creating a backup copy of the file before proceeding is recommended. With a text editor, edit the "descr_strat" file in the "\activision\rome - total war\data\world\maps\campaign\imperial_campaign" folder. Scroll down to locate the faction to change. In this section there is a line that starts with the word "unit" that allows values relating to experience (0-9), armor rating (0-3), weapon level (0-3) to be changed. Once edited, you can copy and paste that line a maximum of twenty times to create that number of units in that army. -Note: This procedure requires editing a game file; creating a backup copy of the file before proceeding is recommended. With a text editor, edit the "export_descr_unit" file in the "\activision\rome - total war\data" folder. It will be a large data source for unit information, were you can edit the units to your pleasure. To make your archers more powerful, scroll down and locate the quot;roman_archer_auxillia" entry about two thirds of the way down. Each unit has its information set together with a break between the other unit information. The unit names are at the top. Go down to "stat_pri" of the "archer auxillia". The first number is the attack power. You can increase this to about 70. You increase it more, but it will not count the attack higher than the maximum number. The following number is for when the unit charges, and how much bonus it gets to its attack from that. Next is what the unit fires (if they can shoot anything). After that is the unit range of the weapon (increase this). After that is the ammo per man (increase this). You now have an incredibly powerful archer unit for all Romans to use. At the bottom is the ownership. You can delete the other faction names if desired, so only you can use them.
-Another thing you can do is change Peasants into Phalanxmen, or Hoplites. Go to "roman_peasants" andscroll down to "formation". Next to "horde", type , Phlanx, (include the commas and space). They can now form a phalanx and will have spears. You might have to change the original formation from "horde" to "square" to do this. However, you cannot add the formation "testudo" to Peasants and expect for them to have big shields.
