Bullet mechanics?

[Doom2fan]

• Penetration?
  • Could be for walls, or bodies...
  • Could make bodies block bullets, and certain bullets can penetrate...
• "Physics-based" damage? Controlled by velocity, shape and size.
• Enemy armour? Would tie in with the former.
• Buckshot does more damage to certain enemies?
• Would be nice for damage to be balanced around feeling nice
  • Basic human enemies dying in a few pistol shots?
  • Two 10 or 12ga shots to kill a pinky?
  • It feels nice to clear a room quickly, with hectic shootouts...
• "Scaling" the range of spread? Same ratio between distances, but spread actually means something in normal Doom encounter distances.
  • e.g., Pistols have noticeable spread, rifles are more accurate.
  • Could break away from reality a bit for the sake of gameplay...
• A better armour system (Improve the way armour works and add bullet penetration #96)
• Stun?
• Headshots?
