I wanted to make a little thingie on thermal clips, and how the guns work in the Mass Effect universe:
In the galaxy of Mass Effect, all arms use a solid block of metal to fire off the projectiles. The onboard computer systems check for distance to shear off an appropriate size slug to be fired by a mass accelerator in the weapon. All slugs are designed to crumple on impact (except for armor piercing rounds) to increase maximum damage, because a small hole in a person is less damaging than pure kinetic force applied directly to the target. The gun runs on thermal energy, stored in thermal clips. In recent technological advancements, procured by the geth, weapons can eject their thermal clip to avoid overheating, which potentially harm the weapon. The advancement allowed for troops to fire faster, without the need to worry of overheating. Different ammunitions can be applied from the user's omni-tool to the weapon, i.e. armor piercing rounds, warp rounds, and incindiery rounds.
