Well, as far as guns go, think mass effect in terms that all weapons mostly are ballistic still but do not require the usual bullet cartridges, instead they use Krillium cells which is supposed to be a material found in the planet that's comparable to Lithium-ion batteries but like 100 times better and are also rechargeable on the field. The only draw back of the weapons is that the metal is prone to overheat if continually fired in spray. Some other guns do still use cartridges like Shotguns, but Assault Rifles, handguns and SMGs do use the other system. Sniper Rifles are mini rail guns, think of them as futuristic siege weapons but far more portable, the only drawback is that they overheat quickly and need recharge time once the ammo capacity has been depleted but they self supply as well as the rifles as long as the battery cell has power.
