Actually, I have been thinking of some completionist medals....
- Like... participating in a mission with each UFO type.
- Getting Kills/Stuns with each class of weapon : melee, pistol, rifle, heavy, launcher, grenade (This actually may get cumberson due to having to define each weapon, and mods would not be accounted for)
(Edit: The usable battle types are : 1 - Firearm, 2 - Ammo, 3 - Melee, 4 - Grenade, 5 - Proximity Grenade. Not sure if Rocket Counts as Ammo)
- Getting Kills/Stuns with each class of Damage : AP, HE, Laser, Plasma, Stun, (Optional: Melee, Smoke, Incendiary, Acid) (Maybe any 5 of the above)
