10 Items That BROKE Video Games
3. Dart Gun - Fallout 3
Essentially a tiny crossbow, Fallout 3's dart gun can only be obtained via weapon crafting. While the schematic to make the dart gun can only be obtained in a few places, the resources required to build it plentiful, as is its unique ammunition. People in pre-nuked Washington D.C. really liked playing darts, I guess.
Naturally the base damage of the dart gun isn't especially high. Less naturally, however, is its ability to instantly cripple both legs of an enemy. And you don't even need to aim for the legs; a hit anywhere will have them limping toward like a tortoise with broken legs. And it works on just about any organic enemy.
On top of that, the darts are poisoned. At a high enough level anything you shoot will be dead in a just a few agonizing paces.
But one of Fallout's best design choices is how danger generally increases the farther you stray from civilization. Exploring the far reaches of the map should come with a little anxiety. Without it, exploration for exploration's sake just feels a bit hollow. Anything that turns a Deathclaw into an inconvenience should probably be rebalanced.
