I've analyzed the alien weapon. Its design is most intriguing. I have no idea how they fit such a potent power supply into such a small package. It fires bolts of plasma contained within a self-sustaining magnetic bottle that ruptures upon striking the target, releasing a great amount of heat and electromagnetic energy. It appears to be designed for combat in vacuum, as it generates very little recoil.
It is particularly effective against unshielded electronics and human flesh. Your armor is heavily shielded, which explains why it has provided such good protection.
I would very much like to study it in detail with the advanced sensors available in the science bay, but I realize that you have no time for that now.
I have reverse engineered the most basic elements of the trigger mechanism. With a simple upgrade, your suit should be able to operate both the pistol and rifle models you've found. Unfortunately it involves additional hardware.
Bring it to the engineering bay and place it under the scanner indicated on your automap. I will use the nanofacts to construct a trigger mechanism for you. Then you'll be able to use the alien weapons against them.
