Multishot/mod explanations

[Zelex]

Just got multishot and not sure what it does, wich brings me to the idea that mods need tooltips to explain their functions.

Same here for Puncture, my guess is that it makes bullets go through enemies (so puncture 2 would mean that it can pass through 2 enemies), but I'm really not sure.

As for multishot, it adds more bullets on your shot. For example for my bronco shotgun, it goes from 8 bullets to 10.86. What I don't know is how the decimals are handled. Does it rounds up or down, or do I shot 11 pellets 86% of the time and 10 the other 14% ?

Also the skills and mostly the skills upgrades lack description. What does upgrading electric shiel do ? What does upgrading radial blind do ? This is explained nowhere and I can't seem to find any difference in-game.

Some insight from the devs would be nice.

I know punture goes through enemies and thin walls. was the first mod i got and oh man does it help with sheild troops :) i think skills just upgrade range and damage. or how long they last.
