Does anybody know which tools are needed in order to open the files? (Aix files)
I've no idea, already been looking around but I cant find them :(

I've tried to do this but till now no success. If I figure it out I let you know.

Wow thanks. =) Really appreciated. But do you know how to open those aix files for the archery? I dont seem to have the tools for :confused:

I can just open them in notepad. Not sure if that is right or not.

You must see the efficiency of irregulars archers in term of battle economy, also if in multiplayer is more clear: they are many for single unit and they are cheaper. With the cost of a single elite archer or horse archer I can take 9 irregular archers. When i use them in battle I never make 1 to 1 shoot but I concentrate the fire of 4-5 units on a single target (especially if unarmoured): this mean salvos of 400-500 arrows on a single target of 100-200 men. This mean at medium range a wounded can be hit also two or three times: this create three penalties: woundeds, deads, heavy arrows rain. after two or three salvos a unarmoured unit can start to blink white, causing moral penalties also to near units.
Western archers are also the only weapons to oppose to light horse archers, because these one have more arrows than foot archers and crossbowmen load too slow, so a good players can be out of range much before the crossbow is loaded. Irregular compensate with number and rapidity.

FOr make a comparison: at Crecy the english bownmen launch near a million of arrows during the battle, but the bigger part of losses was caused by close combat. At Agincourtn the arrows create chaos and woundeds but the knights dead in the initial charge were only 3.

Elite archers are yes destructives but only 50 for units and very expensives, you can take them only if your penalize your heavy infantry or heavy cavalry.

aix files are just common txt files so you can edit them even in notepad. But I suggest "editoraix" from the modding tools (link posted by mitra here). It has syntax highlightening and divides rather long file into subsections. btw "editoraix" is built in editor you've got with the game.

mitra would you be so kind to ask devs about this variable:
This is only info I've found. AFAIK it's about terrain type where a unit stands. It has an influence on all ranged units and their targets. I'd like to know which number in 0-9 range represents which terrain?

I have it in russian (google translator after but is not clear what is the better translation of second word), perhaps Sneaksie can give us the better translation

8 thick forest, the second interval
9 Thick forest, the third interval

Thx a lot! These 3 kinds of "interval" are still unknown to me but at least I know it's about forests.

The translation is literally correct (sparse forest is better than 'rare' one though), i'm not sure what these intervals mean.
