The Fallout series is an absolute goldmine for ridiculous, unreliable weaponry, often crafted from a mix of Cold War remnants, alien hardware, and scrapyard waste. However, for its sheer destructive power, the Experimental MIRV takes the cake. Early on in Fallout 3, the player is given access to the Fat Man gun. This device functions similarly to a grenade launcher, except it catapults mini nukes instead of puny lesser explosives. Able to cause its own miniature nuclear fallout, the Fat Man is already an extremely dangerous weapon in its own right. Enter the Experimental MIRV. Making even the Fat Man look like an air rifle in comparison, the MIRV launches a grand total of 8 mini nukes at once. Not only is this far more firepower than anyone could possible need, it's also packaged in the most unreliable weapon imaginable. Even fired with extreme precision, the destructive capabilites of 8 mini nukes exploding simultaneously puts the firer in a very dangerous position. The MIRV is far from accurate though, and is essentially just a fancy metal enclosure for a big catapult. The eight nukes can end up anywhere in a 180 degree arc in front of the weapon, meaning extreme collateral damage that might not even hit the original target in the first place. Factor in the frequent jamming, and the loss of eight valuable nukes with each press of the trigger, and you're left with what is absolutely the most impractical video game weapon of all time. To its credit though, it's a real achievement to cause noticeable damage in a place named the 'Capital Wasteland'. https://www.youtube.com/watch?v=TKCNdjbRao4 Which are your favourite impractical weapons in video game history?
