Hello.
Rifle firerate - You discovered a bug that I didn't notice while working on Revival. The unknown author of this cheat used a direct line from the list of items to which the change is to be applied. I didn't realize that newly created weapons had to be added to this list. It's a rather inappropriate solution, the author should have set the change for all sniper rifle weapons type. Unfortunately, as I said, I didn't notice.
If you would like to add a weapon to the list yourself using the Reanimator, proceed as follows:
First, find the row with the weapon in the "items" table and remember its number. For example: in the column "String_string" find the name of the unique sniper rifle "Bull's Eye", the row number is 965.
Then, in a regular text editor, open the "install.xml" file in Revival. Find one of the three rifle fire rate commands (the one you want to use, for example <title>Improved Sniper Rifle Fire Rate 34</title>) and add the weapon line number to the list of numbers below (entity id="number, number, number").
All robots at once - no, this is not possible. You would have to program a whole new skill, which would be very difficult.
