Okay, I'm confused about somethings already. You modded the binary files? I didn't know that was possible...

Anyways, if you made a mod with a lowered value for the damage, it should take effect once you activate the mod.

Another thing to note is that the damage in the .entity file is not the damage that is displayed in the game, the game displays a rough damage per second, the entity file is damage per hit.

Hope that helps...

I think to it to show the new info to say what you've changed it to you have to rename the string file.

go to the same location as where the game info folder is, a few folders below this is a folder named "strings". Scrole down until you find relivant discription. In your case "psi beam defence' it also gives you a breif discription of what it does dont alter that just rename it eg. change "psi beam defence'(Im not sure wether its in that order without looking at it but will be something along the lines of this) to "psi beam defence plus' or what ever as long as its different. that way the computer willread the change.

Hope this helps. Oh  ! and it may take awile to find but I think, from memory it was about 2/3's the way down the list.

Good luck!
