First: Be Saxons because its the only faction i tested with. Ok get half sea raiders and half saxon keels charge in with raiders and kill the remains with your keels its very simple(if it doesnt work try better units like chosen axes and wahteve is afer raiders in unit list.)
Modify money , soldier's weaponry and more
Firstly, note that this is not a cheat but a system files change. Go to program files/Activision/BI/Data/world/maps/campaign/imperial_campaign. There you should find a text file called "descr_strat.txt". I would advise you to copy it to a safe place before proceding. After you have a back up file of it, Open this file (the prototype one, not the back up one!). There you should see some factions categorised in playable, unlockable and unplayable. If you want
to play with one of these factions, cut it and paste it under "Playable" and it should be allright. Remember when you do this, try to make the files look "as was" sp that there are no spaces. That could lead to a crash to your program.
If you want to change a faction's money or troops exp wpns and armor, in descr_strat.txt, you can find all the faction's info and change it . For example, after the list of the playable unlockable and unplayable factions, follows a big list of resources. After this list, there is a faction( i dont remember which one). Select the money of the faction, erase them completely (only the numbers) and type 9999999999 . That should bring you unlimited money. Watch it, if you type more than 10 numbers, denary may go, minus.
