A: lasguns, lascannons, plasma weapons and Melta weapons are all what i think can be safly called non-kinetic energy weapons.and by the way, why is man still using projectile weapons in the 41st millenium?
Exactly. Imperial technology isn't really in a state of development or invention (they've been using the same stuff for the last 10000 years) and is all based on the records of designs which survived the Age of Strife and so forth. Besides, if the weapons were too high tech the entire idea of a basic infantryman would go out the window.
I think they did, i believe they are called necrons...
BTW..one thing i dont see in the IG that seems like it would fit.. Androids. Heck.. they could make a whole other faction out of Androids if they wanted to expand on the game/universe.
