For some days i make extensive but unsuccessful search for files containing information about initially content of Laputa store (guns, knifes etc. for first mission). If anybody know it, please, pick me this file(s)!

Not sure what you mean. If it's the inital (starting) equipment you're talking about it's in the Equipment.txt file under a string called "start_quant INT" (i.e. the amount of this item generated at the start of the game). In the equipment.txt file look under reticulan power cell or reticulan laser pistol or browning knife... these are the only equipments with a value of more than 0 in the "start_quant INT" string.

[Note:- some of the equipment is under the character inventory in the initial_squad.txt file. ]

This information was in Trashman's post "Tutorials and a joint community project?" which is pinned at the top of this forum.

If you're looking for the glossary writeups then it's in the pack.txt file under the LocalizationPack.vfs

Damn! Thank you! This is be stupid question, i'm pick all i need with you guiding. Thank you again!

PS As always sorry my bad english.
