Hmm, ive never really used motion scanners that much, might have to try that soon. It can detect through walls and stuff right?
Motion Scanner and HE Pack/Nades, or mabye a laser pistol.
If you've downloaded UFO from here then you should be able to run it in windowed mode in dos-box. Try dragging the UFO.exe to Dosbox.exe that might make it work, otherwise im not too sure how it will work in windowed mode for you.
I find that when using either heavy lasers or heavy plasmas the damage doesnt make that much difference, you hit an etherial with a heavy plasma or with a heavy laser and it generally goes down in one hit, its only whether you hit the alien or not, give a heavy laser to a sniper and he can kick some serious behind, that is unless its mutons, mutons should only be dealt with rockets, grenades, High Explsoves, Blaster Launchers and auto-fire from heavy plasma, preferably all..... at the same time.
Either that or you can Mind Control them and make em shoot each other
