No i meant one like on Fallout 3 
... if it's got rotating barrels it ain't a chaingun...
... and since the poor put-upon aliens are so deprived of new weapons lets give them a new one... a very REASONable one for mid-late game...
... a couple of dozen rotating railgun barrels firing DU needler rounds and powered by a steamer-trunk sized combination ammo pack and power cell...
... an Ortnok would trot along carrying the pack in one hand and the weapon in the other.... when he stops he drops the trunk and takes hold of the weapon with both hands to either pose with it or use it...
(see Neal Stephenson's Snow Crash for details)
Hey, I just had the thought that the aliens would be more vulnerable and far more immediately affected by ionizing radiation than humans. They have more "brain" cells but those cells are spread throughout the body and thus offer more targets for randomized particle hits... perhaps something to hold in reserve if needed for game balance later? Either the aliens get desperate and risk the damage from power packs and weapons that emit ionizing radiation in order to field more powerful weapons... or the humans realize what such can do to the aliens and start using hot stuff to even the odds. Just a thought...
