Bloody Mess

Bloody Mess is a Fallout, Fallout 2 and Fallout Tactics trait, as well as a Fallout 3 perk.

Fallout, Fallout 2 and Fallout Tactics
By some strange twist of fate, people around you die violently. You always see the worst way a person can die.

This trait does not alter gameplay other than the fact that you get to see the violent death animations more often. However, it does have an effect on the ending of Fallout.

Note: Bloody Mess has a positive impact if you plan to use the Super Sledge. If someone dies the death is instant instead of first rolling down half of the game screen.

Fallout 3
As traits were completely removed from Fallout 3, Bloody Mess was changed into a perk.
 * Requirements: Level 6
 * Ranks: 1
 * Benefit: Aside from people around you always dying violently, you’ll also do 5% extra damage with all weapons.

Keep in mind that exploded corpses can be difficult to loot. On the other hand, enemies in hard to reach locations who are "gibbed", such as the Super Mutants found in the skywalk near the Irradiated Metro, can be easier to loot when their pieces fall into an easier to reach location. Also keep in mind in Fallout 3 enemies killed with this perk just explode into gibs with a higher chance, and it seems that special death animations (Laser and plasma ash/goo, for instance) Will happen just as much. This perk is more useful if you plan to carry and use a wide variety of weapons since its 5% bonus is applied across the board.

In the German version, which is free of all blood and physical sundering, there is no change in the battle and death animations.
